Noh YH, Jung KI. The Relationship between Myopia and Obesity in Adults. KOREAN JOURNAL OF OPHTHALMOLOGY 2024; 38:137-146. [PMID: 38449306 PMCID: PMC11016688 DOI: 10.3341/kjo.2023.0102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 02/27/2024] [Accepted: 03/05/2024] [Indexed: 03/08/2024] Open
Abstract
PURPOSE To investigate the relationship between myopia and obesity through direct measurements of fat content. METHODS A cross-sectional study used a stratified, multistage survey, the Korea National Health and Nutrition Examination Survey (2008-2010). Subjects 19 years or older (n = 10,305) were included. Participants were divided into three groups according to refractive status: myopia (spherical equivalent [SE] ≤ -1.0 diopter [D]), emmetropia (-1.0 D < SE ≤ 1.0 D), and hyperopia (SE > 1.0 D). Obesity was investigated with assessment of fat mass and body mass index or waist circumference. Fat mass was measured with whole-body dual energy x-ray absorptiometry. Body fat percentage was calculated as (total fat mass / body weight × 100). RESULTS Higher obesity index was found in individuals with myopic eyes after adjustment for age, sex, education level, income status, physical activity, residence, and serum vitamin D level. The significant difference in total body fat percentages among myopia, emmetropia, and hyperopia was significant in the young age group (19-39 years, p < 0.05) but not in the middle age group (40-64 years) and the old age group (≥65 years). Individuals with a higher percentage of total body fat had greater odds ratios for myopia (fourth quartile of body fat; odds ratio, 1.352; 95% confidence interval, 1.178-1.551). CONCLUSIONS An association was found between adiposity and myopia in relatively young adults using direct measurements of fat mass.

Abstract
OBJECTIVES This study evaluated the relationship between acquired cataract's different types and the ABO and Rh blood classes. METHODS Overall, 520 patients, by randomized sampling method, participated in this retrospective cross-sectional study. After reviewing the patient's medical records and laboratory results, the patient's demographics, ABO group, Rh, and cataract type were documented. RESULTS A total of 520 patients were included in the research, with a mean age of 67.57 ± 11.85. Most of them were female (n = 286, 55%). Mix (n = 230, 44%) and nuclear sclerotic (NS) (n = 167, 32%) cataracts were the most common types. The posterior subcapsular cataract (PSC) prevalence in females was significantly higher than in males (16.1% vs.7.3% p = 0.002). Also, men had more NS cataracts than females (89, 38% vs. 78, 27.3%) (p = 0.009). Patients with PSC were significantly younger than others (all p-values < 0.001). Our results showed that cataract types are independent of blood group types and Rh (P > 0.05). CONCLUSION Although our findings showed that cataract types are independent of blood group types and Rh, they can be compared with future studies on the association of other Blood-Group Systems in developing acquired cataracts.

Abstract
Myopia is the leading cause of visual impairment in the world. With ever-increasing prevalence in these years, it creates an alarming global epidemic. In addition to the difficulty in seeing distant objects, myopia also increases the risk of cataract and advances its onset, greatly affecting the productivity of myopes of working age. Cataract management in myopic eyes, especially highly myopic eyes is originally more complicated than that in normal eyes, whereas the growing population of cataract with myopia, increasing popularity of corneal and lens based refractive surgery, and rising demand for spectacle independence after cataract surgery all further pose unprecedented challenges to ophthalmologists. Previous history of corneal refractive surgery and existence of implantable collamer lens will both affect the accuracy of biometry including measurement of corneal curvature and axial length before cataract surgery, which may result in larger intraocular lens (IOL) power prediction errors and a compromise in the surgical outcome especially in a refractive cataract surgery. A prudent choice of formula for cataract patients with different characteristics is essential in improving this condition. Besides, the characteristics of myopic eyes might affect the long-term stability of IOL, which is important for the maintenance of visual outcomes especially after the implantation of premium IOLs, thus a proper selection of IOL accordingly is crucial. In this mini-review, we provide an overview of the impact of myopia epidemic on treatment for cataract and to discuss new challenges that surgeons may encounter in the foreseeable future when planning refractive cataract surgery for myopic patients.

Abstract
Age is the biggest risk factor for cataracts, and aberrant oxidative modifications are correlated with age-related cataracts, suggesting that proper redox regulation is important for lens clarity. The lens has very high levels of antioxidants, including ascorbate and glutathione that aid in keeping the lens clear, at least in young animals and humans. We summarize current functional and genetic data supporting the hypothesis that impaired regulation of oxidative stress leads to redox dysregulation and cataract. We will focus on the essential endogenous antioxidant glutathione and the exogenous antioxidant vitamin C/ascorbate. Additionally, gene expression in response to oxidative stress is regulated in part by the transcription factor NRF2 (nuclear factor erythroid 2-related factor 2 [NFE2L2]), thus we will summarize our data regarding cataracts in Nrf2-/- mice. In this work, we discuss the function and integration of these capacities with the objective of maintaining lens clarity.

Abstract
Background Myopia is an increasingly serious public concern, particularly among primary school students. The prevalence of myopia and its influencing factors in primary school pupils in Eastern China during the COVID-19 pandemic had not been explored. Methods A randomly clustered sampling method was performed, and selected pupils from grade 1 to grade 3 in 15 primary schools in the Fenghua District of Zhejiang Province were included and given myopia screening and uniform questionnaire survey 1 year later. Results A total of 4,213 students completed the myopia screening and questionnaire survey. Myopia was diagnosed in 1,356 pupils, with a myopia incidence of 32.19%. The spherical equivalent (SE) refraction of the included pupils decreased on average by 0.50 ± 2.15 D 1 year later. The myopia rate was positively correlated with the increase of grade, in which the myopia rate among grade 3 students was the highest at 39.69%. The myopia rate among female students was higher than that among male students. Students residing in urban areas had a higher myopia rate than in rural areas. Maintaining an near work distance ≥33 cm was a significant protective factor (OR = 0.84, 95% CI: 0.74-0.96). Students with two myopic parents had a higher risk of myopia (OR = 1.61, 95% CI: 1.34-1.92). Conclusion During the COVID-19 pandemic, the myopia rate among early primary school students in Eastern China was high. More attention and implementation of interventions from health and education departments, such as training the development of good eye behavior, should be considered to strengthen the intervention of myopia in primary school students.

Abstract
Cataracts remain the first or second leading cause of blindness in all world regions. In the diabetic population, cataracts not only have a 3–5 times higher incidence than in the healthy population but also affect people at a younger age. In patients with type 1 diabetes, cataracts occur on average 20 years earlier than in the non-diabetic population. In addition, the risk of developing cataracts increases with the duration of diabetes and poor metabolic control. A better understanding of the mechanisms leading to the formation of diabetic cataracts enables more effective treatment and a holistic approach to the patient.

Abstract
Introduction Anesthesiology is a specialty of medicine that focuses on inducing reversible loss of consciousness, amnesia, muscle relaxation, and analgesia. Anesthesiologists play an important and integral role in pain clinics, operating rooms, and intensive care units (ICU). This study assessed public awareness and knowledge about the specialty of anesthesiology and the role of anesthesiologists in Qassim province, Saudi Arabia. Methods An observational, cross-sectional study was conducted in Qassim province from September 2022 to December 2022. A modified electronic questionnaire was distributed through social media platforms. The questionnaire contained items designated as demographics, knowledge, and experience regarding anesthesia and the importance of anesthesiologists. Saudi participants older than 18 years of age were eligible to complete the survey. Results Of the 405 participants, 375 met the inclusion criteria (48.5% women and 51.5% men), and participants with an undergraduate education level (23.5%, p<.05) had a higher prevalence of having undergone surgery previously. Furthermore, it was found that factors, such as knowledge about the complications of regional anesthesia (p<.001) positively influenced anesthesia knowledge. Moreover, in a linear regression model, an understanding of the complications of regional anesthesia was associated with increased anesthesia knowledge (p<.05). However, the sample demonstrated a poor level of anesthesia knowledge, evidenced by the responses to questions assessing the same. Conclusions Consistent with the literature, there was a poor level of anesthesia awareness and knowledge among the adult population living in Saudi Arabia. Further research is needed to establish the link between anesthesia awareness, knowledge about the role of the anesthesiologist, and knowledge about anesthesiology in the region.

Abstract
PURPOSE To comprehensively determine the associations between systemic medications and surgically treated cataract in the US population. DESIGNS Retrospective cross-sectional study. METHODS Participants aged ≥40 years from the 1999-2008 National Health and Nutrition Examination Survey (NHANES) were included. Surgically treated cataract was defined as cataract requiring a procedure. Data on prescription drug use over the past 30 days were collected via home interviews. Drug categories for ophthalmic indications and those prescribed in less than 0.5% of the participants were excluded from the analysis. Separate logistic regression models were used to explore associations between each drug category and surgically treated cataract. The Benjamin-Hochberg procedure was used to control the false discovery rate. RESULTS A total of 14,931 were included in the present analysis. The weighted prevalence of surgically treated cataract was 9.6% (n=2010). We identified 20 drug categories that had significant associations with surgically treated cataract, of which 8 associations remained statistically significant after further adjustment for pertinent comorbidities. The 3 drug categories with the highest odds ratio (OR) values were tricyclic antidepressants (OR, 2.21; 95% CI, 1.38-3.51; P = .001), insulin (OR, 2.13; 95% CI, 1.48-3.07; P = 9.41×10-5) and group III antiarrhythmic agents (OR, 2.00; 95% CI, 1.25-3.19; P = .004). The use of sex hormone combinations among women reduced the risk of having surgically treated cataract (OR, 0.011; 95% CI, 0.001-0.089; P = 5.98×10-5). Dose-response relationships were observed for all 8 drug categories. CONCLUSIONS Our comprehensive evaluation provides new knowledge on the complex relationships between systemic medications and surgically treated cataract.

Abstract
PURPOSE Although perioperative blood-pressure control is important, especially for high-risk patients, no previous report has examined early monitoring of perioperative blood-pressure changes before cataract surgery. In this single-center, retrospective, observational study, we evaluated the early intervention for perioperative hypertension in cataract surgery with topical anesthesia. METHODS Hospitalized patients who underwent phacoemulsification and intraocular-lens insertion and whose blood pressure was controlled using standardized management to start early monitoring and control (standardized group; 134 eyes of 134 patients) were compared to age- and sex-matched patients who underwent the same cataract surgery and whose blood pressure was controlled using conventional means (control group; 134 eyes of 134 patients). The perioperative blood pressure, pulse pressure, and heart rate were compared preoperatively, upon entering the operation room, and at the beginning, end, and after the operation. RESULTS Although there was no difference before the operation, the changes in systolic pressure in the standardized group were significantly lower at the point of entering the operation room, at the beginning of the operation, and at the end of the operation (P = 0.003, < 0.001, and < 0.001, respectively). No significant difference was observed between etizolam and nicardipine use. CONCLUSION Early monitoring and control of blood pressure in cataract surgery could effectively control perioperative hypertension without additional drug use and could be widely applied in the clinical setting.

Abstract
BACKGROUND The aim of this study is to investigate the prevalence of myopia and high myopia and the associated risk factors in key schools in Xi'an, China. METHODS This cross-sectional study started in September 2021 and was conducted for one month. A total of 11,011 students from 10 key primary schools, five key junior high schools and five key high schools in Xi'an were randomly selected to undergo visual acuity measurement and non-cycloplegic autorefraction. The questionnaire was completed by the students and their parents together. RESULTS The prevalence of myopia and high myopia in key schools were 75.7% and 9.7%, respectively. The prevalence of myopia and high myopia rose significantly as grade or age increased (all P < 0.001), and the prevalence of myopia and high myopia in females was higher than that in males (P < 0.001, P < 0.5). According to the multivariable logistic regression analysis, older age (OR=1.42), female compared with male (OR=1.43), having one myopic parent (OR=1.64), having two myopic parent (OR=2.30) and often taking extracurricular tuition (OR=1.35) were more likely to be associated with develop myopia (P < 0.001). Older age (OR=1.39), having one myopic parent (OR=2.29), having two myopic parent (OR= 3.69), and often taking extracurricular tuition (OR=1.48) were more likely to be associated with high myopia (P < 0.001). CONCLUSIONS The overall rate of myopia and high myopia in key schools in Xi'an, China, is extremely high. Myopia and high myopia are associated with increasing age, parents' myopia, few outdoor exercises, and extracurricular tuition. Myopia is also associated with female and not having the habit of "one punch, one foot, one inch (when reading and writing, 10 cm from the chest to the table, 33 cm from the eye to the book and 3.3 cm from the tip of the pen to the finger)".

Abstract
PURPOSE Unclean cooking fuels such as wood and kerosene have been associated with cataract in cross-sectional studies. This study sought to determine whether exposure to unclean cooking fuels was associated with subsequent cataract progression. DESIGN Prospective cohort study. METHODS This is a secondary observational analysis of the community-based Antioxidants in Prevention of Cataracts trial (ClinicalTrials.gov ID NCT01664819). The exposure of interest was cooking fuel type, measured at baseline. Main outcome measures were baseline cataract severity and self-reported cataract surgery at a 15-year visit. RESULTS Baseline and 15-year follow-up data were available for 798 and 579 participants, respectively. Wood or kerosene was used by 711/798 (89.1%) baseline participants, including 539/579 (93.1%) participants with complete follow-up. Cooking fuel type was not associated with cataract severity at baseline (p=0.443). Out of 8,334 person-years of follow up, 90 cataract surgeries were observed over 15 years (1.08 surgeries per 100 person-years; 95%CI 0.87-1.32). Use of wood or kerosene was not associated with 15-year incidence of cataract surgery relative to individuals using propane (adjusted p=0.154). Cataract surgery was more common in older individuals (HR 1.1 per year, 95%CI 1.1-1.2, p<0.001), those with baseline myopia (HR 2.1, 95%CI 1.2-3.5, p=0.009) and women (HR 3.5, 95%CI 1.2 to 10.1, p=0.019). CONCLUSIONS This study found no association between unclean cooking fuels and cataract progression over a 15-year period. No other modifiable risk factors were associated with incident self-reported cataract surgery.

Abstract
OBJECTIVES To evaluate the risk of developing eye lens opacities and cataracts among physicians and healthcare workers occupationally exposed to radiation. METHODS Our literature search captured articles published in Embase, Web of Science, PubMed, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, and Google Scholar databases until September 2021. Then, we retrieved articles reporting cataracts and eye lens opacities induced by radiation exposure among healthcare professionals. The outcomes of interest were cataracts, nuclear opacity, cortical opacity, posterior subcapsular opacity, and any lens opacity. RESULTS Of the 4123 articles identified, 15 studies met the inclusion criteria. Healthcare workers exposed to radiation had a significantly greater risk of posterior subcapsular cataracts (PSCs), cataracts, and any lens opacities than those of the non-exposed participants (p<0.05). The cortical opacity was not significantly different between the exposed and non-exposed participants (p>0.05). Radiation was not determined to be a risk factor for nuclear opacity as it was significantly greater in the control group than the exposed participants. Subgroup analysis revealed that nurses had the highest risk for PSCs (risk ratio = 4.00), followed by interventional cardiologists (risk ratio = 3.85). CONCLUSION The risk of posterior subcapsular opacities and cataracts is significantly higher in healthcare workers with occupational radiation exposure than in non-exposed workers, highlighting the necessity to enhance and promote the wearing of protective measures with high safety levels.

Abstract
Cataract is the leading cause of blindness worldwide, and metabolic syndrome (MetS) is a known risk factor. In this study, we investigated the association between the risk of cataract with MetS and its components in a large-scale study. Data were derived from the Taiwan Biobank, and 121,380 individuals were included. The NCEP-ATP III criteria modified for use in an Asian population were used to define MetS and its components. The occurrence of cataract was identified through a standardized interview and self-reported questionnaire. Multivariable analysis showed that MetS (OR, 1.129; 95% CI, 1.0175−1.184; p < 0.001), low high-density lipoprotein (HDL)-cholesterol (OR, 1.057; 95% CI, 1.005−1.113; p = 0.032), and hyperglycemia (OR, 1.162; 95% CI, 1.108−1.218; p < 0.001) were significantly associated with cataract. Furthermore, a stepwise increase in the prevalence of cataract corresponding to the number of MetS components was found. The presence of three MetS components (vs. 0; OR, 1.103; 95% CI, 1.024−1.188; p = 0.010), four MetS components (vs. 0; OR, 1.137; 95% CI, 1.040−1.242; p = 0.005), and five MetS components (vs. 0; OR, 1.208; 95% CI, 1.059−1.378; p = 0.005) were significantly associated with cataract. In conclusion, significant associations were found between a high incidence of cataract with MetS and its components, including low HDL-cholesterolemia and hyperglycemia. Further, a stepwise increase in the prevalence of cataract corresponding to the number of MetS components was also found. The results of this study indicate that MetS may increase the development of cataract in Taiwan.

Abstract
Purpose To assess the impact of cataract in ageing population by evaluating the prevalence, incidence, and background factors of cataract and cataract surgery. Patients and Methods Two health examination surveys representing Finnish population in 2000 and 2011 included 7380 and 5930 participants aged 30 years or older with cataract status known. An 11-year follow-up included 4840 persons who participated in both the surveys. The data include information on physician-made diagnoses, socio-demographic factors, and lifestyle factors based on self-reported assessment. Cataract diagnoses and surgeries recorded in the Finnish Care Register for Health Care were linked to the survey data. Cataract patients were compared to those without cataract using logistic regression. Differences in cataract surgery age were evaluated using linear regression. Univariable and multivariable models were included. Results During 2000–2011, the prevalence of cataract increased from 8.8% to 13.6% and cataract surgery from 5.7% to 8.9% in a representative sample of the Finnish adult population. Cataract and cataract surgery were associated with age, smoking, and high alcohol consumption. Cataract was also associated with female gender and low income in 2000, but this association declined during the 11 years. Smoking and high alcohol consumption were associated with younger surgery age. Conclusion The prevalence of cataract and cataract surgery is increasing with the ageing of the population. The increase in cataract surgery is likely also reflecting the improvements in eye care. The possibility to equally use health-care services throughout a country can reduce the impact of socio-demographic status. Healthy lifestyle delays the development of cataract, whereas smoking and high alcohol consumption are associated with earlier cataract development. Therefore, the availability of cataract services and promotion of healthy lifestyle will be the key to prevent the detrimental effects of cataract on patients and the society in countries where the population is rapidly ageing.

Abstract
PURPOSE To evaluate and compare the outcomes of live surgery (LS) and no-live surgery (NLS) on cataract surgery with implantation of different types of intraocular lenses (IOLs). METHODS Retrospective, contralateral eye, case series of patients that underwent cataract surgery in live or non-live view during two consecutive editions of national meetings. Both eyes of the same patients were implanted with the same IOL, one in LS and the other in NLS. RESULTS 108 eyes of 54 patients, aged between 50 and 82 (72 ± 8.2) and implanted with different types of IOLs, were reviewed. Both eyes in each patient were well matched at baseline in terms of intraocular biometric characteristics, corneal curvature and endothelial cell density (ECD) (p > 0.05). There are no statistically significant differences between the biometric and topographic parameters, aberrometric data and the loss of ECD in the post-operative outcomes (p > 0.05). However, comparing the different types of IOLs, there is a significant loss of ECD in eyes implanted with a toric IOL during LS (p = 0.0014 and p = 0.04, in 2017 and 2018 edition respectively). CONCLUSIONS In this series of live cataract surgery, eyes operated in LS or NLS have comparable outcomes, underlying the importance and the benefits of live view in terms of medical education and the low-risk of complications. Nevertheless, we have found a significant increase in ECD loss in patients implanted with toric IOLs during LS.

Abstract
Cataract and blepharoptosis are both commonly encountered ophthalmic problems in older adults. Since they share similar risk factors, it is plausible that there may be an association between the two conditions. We examined data from the Korean National Health and Nutrition Examination Survey (KNHANES) 2010–2012 to determine if there is an association between age-related cataract and blepharoptosis. Multivariable adjusted logistic regression analysis was conducted to examine the odds ratio (OR) and 95% confidence interval (CI) for association of each specific type of cataract with presence of blepharoptosis. Of the 10,387 eligible participants, 4782 (46.0%) had cataract and 1419 (15.8%) had blepharoptosis. There were more participants with blepharoptosis in the cataract group, compared with those in the no cataract group. After adjusting for potential confounders, participants with blepharoptosis had a higher risk of total cataract (OR: 1.557, 95% CI 1.201–2.019) and nuclear subtype cataract (OR: 1.305, 95% CI 1.050–1.620). Blepharoptosis was associated with significantly higher odds of cataract in obese participants when compared with non-obese participants (p for interaction = 0.0236). Our study revealed a positive association between age-related cataract and blepharoptosis; it suggests that thorough ophthalmic assessment is needed when assessing patients who are planning cataract or blepharoptosis surgery.

Abstract
PURPOSE To investigate which patient-related outcomes are dependent on the experience of the cataract surgeon. METHODS The study was designed as a prospective observational study. Novice (<150 surgeries performed) and experienced (>1000 surgeries performed) cataract surgeons from the Department of Ophthalmology, Rigshospitalet - Glostrup and Nordsjaellands Hospital - Hillerød were included in the study. Patients operated by the included surgeons were examined preoperatively, 1 day, 3 days, and 3 weeks after standard, noncomplicated cataract surgery. Primary outcomes were change in central corneal thickness and endothelial cell loss. Secondary outcomes were best-corrected visual acuity, intraocular pressure, aqueous flare, central macular thickness, and surgical complications. RESULTS Surgery performed by novice surgeons resulted in significantly lower visual acuity (mean -3.6 letters (Early Treatment Diabetic Retinopathy Study (ETDRS)); 95% CI: -7.3; -0.4, p = 0.03) and greater corneal thickness (mean 26.7 µm; 95% CI: 6.8; 46.6, p = 0.01) on the first day postoperative than surgery performed by experienced surgeons. CONCLUSION The experience of the cataract surgeon affected visual acuity and central corneal thickness in the immediate postoperative period. In the future, these patient-related outcomes may be used to assess the technical proficiency of surgical trainees and investigate the effect of different training programs.

Design, methodology, and baseline of whole city-million scale children and adolescents myopia survey (CAMS) in Wenzhou, China. EYE AND VISION 2021; 8:31. [PMID: 34407890 PMCID: PMC8373605 DOI: 10.1186/s40662-021-00255-1] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Accepted: 07/30/2021] [Indexed: 01/19/2023]
Abstract
Background Myopia is the most common visual impairment in children and adolescents worldwide. This study described an economical and effective population-based screening pipeline and performed the project of a million scale children and adolescents myopia survey (CAMS), which will shed light on the further study of myopia from the level of epidemiology and precision medicine. Methods We developed a novel population-based screening pattern, an intelligent screening process and internet-based information transmission and analysis system to carry out the survey consisting of school children in Wenzhou, China. The examination items include unaided distance visual acuity, presenting distance visual acuity, and non-cycloplegic autorefraction. Myopia and high myopia were defined as spherical equivalent (SE) ≤ − 1.00 diopters (D) and SE ≤ − 6.00 D, respectively. Next, the reports of the vision checking were automatically sent to parents and the related departments. The CAMS project will be done two to four times annually with the support of the government. An online eyesight status information management system (OESIMS) was developed to construct comprehensive and efficient electronic vision health records (EVHRs) for myopia information inquiry, risk pre-warning, and further study. Results The CAMS completed the first-round of screening within 30 days for 99.41% of Wenzhou students from districts and counties, in June 2019. A total of 1,060,925 participants were eligible for CAMS and 1,054,251 (99.37% participation rate) were selected through data quality control, which comprised 1305 schools, and 580,609, 251,050 and 170,967 elementary, middle, and high school students. The mean age of participants was 12.21 ± 3.32 years (6–20 years), the female-to-male ratio was 0.82. The prevalence of myopia in elementary, middle, and high school students was 38.16%, 77.52%, and 84.00%, respectively, and the high myopia incidence was 0.95%, 6.90%, and 12.98%. Conclusions The CAMS standardized myopia screening model involves automating large-scale information collection, data transmission, data analysis and early warning, thereby supporting myopia prevention and control. The entire survey reduced 90% of staff, cost, and time consumption compared with previous surveys. This will provide new insights for decision support for public health intervention.

Ophthalmic Epidemiol 2021; 28:48-62. [PMID: 32811260 PMCID: PMC10673649 DOI: 10.1080/09286586.2020.1791907] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2018] [Revised: 06/03/2020] [Accepted: 06/28/2020] [Indexed: 10/23/2022]
Abstract
PURPOSE To identify risk factors associated with lens opacities in Chinese Americans. METHODS A cross-sectional population-based study of 4,582 Chinese Americans ≥50 years residing in Monterey Park, California. Participants completed a comprehensive clinical examination with lens assessment using the Lens Opacities Classification System II, with lens opacities defined by a grade ≥2 in either eye. Participants were considered to have nuclear-only, cortical-only, or posterior subcapsular (PSC)-only if that was the only type of opacity present in both eyes. RESULTS Cortical-only opacity was associated with older age, diabetes mellitus (OR 1.5, 95%CI 1.1-2.1), and family history of cataracts (OR 1.5, 95%CI 1.2-1.9). Nuclear-only opacity was associated with older age, diabetes mellitus (OR 1.4, 95%CI 1.1-1.9), greater waist-to-hip ratio (OR 1.2, 95%CI 1.1-1.4), and high-density lipoprotein (OR 1.1, 95%CI 1.02-1.2). Mixed-type opacities were associated with older age, greater waist-to-hip ratio (OR 1.3, 95%CI 1.1-1.6), and higher HbA1 c (OR 1.3, 95%CI 1.1-1.4). Taller height (OR 0.7, 95%CI 0.6-0.8), greater weight (OR 0.98, 95%CI 0.97-0.99), and higher diastolic pressure (OR 0.98, 95%CI 0.96-0.99) were protective. CONCLUSION CHES identified a strong, dose-response association between age and all types of prevalent lens opacities, which suggests an increasing cataract burden in Chinese Americans based on aging populations. CHES results demonstrate general consistency with previous population-based studies in regard to more sedentary lifestyle exposures (e.g., Westernized lifestyle) and prevalent cortical-only, nuclear-only, and mixed-type opacities, yet also identified further sedentary lifestyle exposures associated with prevalent lens opacities. Improved glycemic control and a more active lifestyle that minimizes factors contributing to metabolic syndrome may help reduce the burden of vision loss associated with lens opacities.

Abstract
PURPOSE To investigate the effect of the diabetes on cataract formation by Pentacam Scheimpflug topography system. MATERIALS AND METHODS Thirty diabetic patients and thirty-five healthy control subjects were included in the study. Exclusion criteria were smoking, high refractive error, any systemic disease or drug usage associated with cataract formation and to have diabetic retinopathy. The duration of diabetes and HbA1c level were recorded. A comprehensive ophthalmologic examination was performed in all cases. Pentacam (Oculus, Wetzlar, Germany) three-dimensional lens densitometer module was used to measure density of anterior, nuclear and posterior lens regions. RESULTS Mean age of group 1 and group 2 was 37.80 ± 5.51 years and 36.51 ± 3.77 years, respectively. There were not any difference between groups in the means of age and sex (P = .271; P = .700). The mean duration of diabetes in group 1 was 4.23 ± 3.71 years (6 months-10 year). The mean HbA1c level was 8.12 ± 2.07% (5.4-12.7%). Anterior, nuclear and posterior mean lens densitometry measurements were significantly higher in group 1 (diabetic group) than group 2 (control group) [(8.90 ± 0.59%; 8.05 ± 0.72% P = < .001), (7.52 ± 0.31%; 7.00 ± 0.59% P = < .001), (7.25 ± 0.31%; 6.90 ± 0.73% P = .006), respectively]. CONCLUSION Diabetes may have cataractous effect in anterior, nuclear and posterior regions of the lens.

Global and regional prevalence of age-related cataract: a comprehensive systematic review and meta-analysis. Eye (Lond) 2020; 34:1357-1370. [PMID: 32055021 DOI: 10.1038/s41433-020-0806-3] [Citation(s) in RCA: 121] [Impact Index Per Article: 30.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2019] [Revised: 10/06/2019] [Accepted: 11/29/2019] [Indexed: 12/22/2022] Open
Abstract
The aim of our study was to estimate regional and global cataract prevalence, its prevalence in different age groups, and the determinants of heterogeneity and its prevalence. For that, we used international databases such as PubMed, Web of Science, Scopus, Embase, and other sources of information to conduct a systematic search for all articles concerning the prevalence of age-related cataract and its types in different age groups. Of the 9922 identified articles, 45 studies with a sample size of 161,947 were included in the analysis, and most of them were from the Office for the Western Pacific Region (19 studies). Age- standardized pooled prevalence estimate (ASPPE) and 95% confidence interval (95% CI) of any cataract, cortical cataract, nuclear cataract, and posterior subcapsular (PSC) cataract were 17.20% (13.39-21.01), 8.05% (4.79-11.31), 8.22% (4.93-11.52), and 2.24% (1.41-3.07), respectively. Significant effects on heterogeneity were observed for the WHO region in the prevalence of any cataract (b: 6.30; p: 0.005) and study year in the prevalence of nuclear cataract (b: -0.66, p: 0.042). In general, the prevalence of cataract not only varies by region but also by age group, and most cases are over the age of 60 years. We examined the sources of variance in the prevalence of cataract and its different types, and identified age as a responsible factor in the prevalence of any cataract, cortical cataract, nuclear cataract, and PSC of cataract, WHO region in the prevalence of any cataract, and study year in the prevalence of nuclear cataract.

Abstract
PURPOSE To investigate effect of metabolic syndrome on blood pressure during cataract surgery with topical anesthesia. DESIGN A single-centered, retrospective case series. METHODS Consecutive patients who were hospitalized and underwent phacoemulsification and insertion of intraocular lens with topical anesthesia in October 2016 were included. Perioperative blood pressure and pulse pressure were compared between patients with metabolic syndrome (metabolic group) and sex- and age-matched patients without metabolic syndrome (nonmetabolic group) at six time points: on admission, in the morning of the operation, 2 hours before the operation, at the point of entering the operation room, during the operation, and after the operation. Perioperative use of etizolam and nicardipine was compared between the two groups. RESULTS Thirty patients in the metabolic group and 30 in the nonmetabolic group were included. There was no difference in changes compared with the values on admission in systolic pressure and pulse pressure at any examination point between the two groups. There was no difference in changes in diastolic pressure between the two groups, except for at 2 hours before the operation (1.4 ± 9.6 mm Hg in the metabolic group vs -6.2 ± 8.5 mm Hg in the nonmetabolic group; P = 0.044). The number of patients who were administered etizolam was 5/30 (16.7%) in the metabolic group and 2/30 (6.7%) in the nonmetabolic group, showing no significant difference. No patients were administered intravenous nicardipine in either group. CONCLUSIONS Well-controlled metabolic syndrome did not affect the changes in perioperative blood pressure during cataract surgery with topical anesthesia.

Abstract
PURPOSE To evaluate the relationship between metabolic syndrome and some of its components with the incidence of cataract extraction. METHODS A population-based prospective cohort with a total of 45 049 men, aged 45-79 years, from the Cohort of Swedish Men completed in 1997 a self-administered questionnaire concerning anthropometric measurements and lifestyle factors. The men were followed from 1 January 1998 through 31 December 2012, and the cohort was matched with registers of cataract extraction. The main outcome measure was incident cases of age-related cataract extraction. RESULTS Over the 15-years of follow-up, 7573 incident cases of cataract extraction were identified. After controlling for potential confounders, the association between single components of metabolic syndrome, abdominal adiposity, diabetes and hypertension and risk of cataract extraction was rate ratio (RR): 1.04; 95% confidence interval (CI): 0.99-1.10, RR: 1.77; 95% CI: 1.64-1.92 and RR: 1.06; 95% CI 1.00-1.13, respectively. The risk of cataract extraction increased with increasing numbers of metabolic syndrome components (p < 0.0001). Men aged 65 years or younger at baseline with all three components of the metabolic syndrome had a relative risk of 2.43 (95% CI: 1.95-3.01) for cataract extraction. CONCLUSION In this cohort of middle-aged and elderly men, metabolic syndrome with the combination of abdominal adiposity, diabetes and hypertension was associated with an increased risk for cataract extraction, especially among men aged 65 years or younger. These findings put emphasis on the importance of weight control and healthy lifestyle behaviours in order to prevent cataract.

Abstract
OBJECTIVE The aim of the study was to compare the risk of cataract in smokers and ex-smokers. METHODS A systematic search of observational studies was carried out in Medline, Embase, and Lilacs databases. Studies that have evaluated the association between cigarette smoking and any type of clinically diagnosed cataract were selected. The association estimators were extracted, adjusted at least by age, and were combined using random-effects models, by subtype of study (cohort, case control and cross sectional), subtype of cataract (nuclear, cortical, and posterior subcapsular), and exposure (current smoker or ex-smoker). Statistical heterogeneity, meta-regression analysis and publication bias were assessed. RESULTS A total of 13 cohort studies, 12 case-control studies, and 18 cross-sectional studies were selected. A risk of cataract was found in current smokers: cohort (OR: 1.41; 95%CI: 1.24-1.60), cases and controls (OR: 1.45; 95%CI: 1.08-1.96), and cross-sectional studies (OR: 1.21; 95%CI: 1.09-1.34); risk of nuclear cataract: cohort (OR: 1.71; 95%CI: 1.47-1.98), case-control (OR: 1.79; 95%CI: 1.43-2.25), and cross sectional studies (OR: 1.45; 95%CI: 1.27-1.65). There was no risk of cortical or posterior subcapsular cataract in ex-smokers. CONCLUSIONS There is a risk of cataract in smokers, particularly nuclear type. With cross-sectional studies, similar results are obtained with cohorts and cases and controls.

Abstract
Background To identify risk factors for the development of presenile nuclear cataract in health screening test. Methods The cross sectional study included a total of 532 eyes of 266 participants aged 30 to 49 years of Samsung Medical Center from February 2013 to April 2015. Presence of nuclear cataract was defined when the log MAR visual acuity with correction was greater than or equal to 0.2 and one or more of the following were met: Pentacam Nuclear Staging (PNS) grading score ≥ 1, average value of nuclear density ≥ 15%, maximum value of nuclear density ≥ 30%. Possible risk factors were obtained from blood tests and questionnaires of a health screening test of Samsung Medical Center. Association between nuclear cataract and risk factors was investigated using univariate and multivariate logistic regression analysis by generalized estimating equation (GEE) models. Results Five factors were significantly associated with presenile nuclear cataract: current smoking [odds ratio (OR) = 2.80, 95% confidence interval (CI), 1.10–7.12, p = 0.0310], non-exercise and high amount of daily physical exercise (OR = 3.99, 95% CI, 1.27–12.52, p = 0.0178; OR = 2.92, 95% CI, 1.38–6.22, p = 0.0053), asthma (OR = 8.93, 95% CI, 1.12–71.15, p = 0.0386), tuberculosis (OR = 4.28, 95% CI, 1.36–13.50, p = 0.0131), and higher total iron binding capacity (OR = 1.01, 95% CI, 1.00–1.02, p = 0.0059). Conclusions Presenile nuclear cataract is related to current smoking, non-exercise or high amount of physical exercise, asthma, tuberculosis, and iron deficiency status.

Exp Ther Med 2018; 16:1520-1528. [PMID: 30116401 DOI: 10.3892/etm.2018.6348] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2017] [Accepted: 02/22/2018] [Indexed: 02/06/2023] Open
Abstract
Recent studies have reported that high glucose (HG) conditions may contribute to the acceleration of renal cell apoptosis and renal fibrosis by inducing epithelial-mesenchymal transition (EMT) of tubular epithelial cells, in which c-Src kinase and transforming growth factor (TGF)-β are key modulators. In the present study, the roles of c-Src kinase and TGF-β in EMT of lens epithelial cells (LECs) under HG conditions were investigated. Results indicated human lens epithelial B3 (HLE-B3) cells under HG conditions exhibited significantly increased protein expression levels of phosphorylated c-Src (p-Src418) (P<0.05) and secreted a significantly increased amount of TGF-β compared with HLE-B3 cells under normal glucose conditions (P<0.05). Notably the c-Src inhibitor PP1 and the activin receptor-like kinase 5 (ALK5) inhibitor SB431542 suppressed EMT of HLE-B3 cells. Results indicated that PP1 significantly inhibited the activities of c-Src and ALK5 and the secretion of TGF-β, whereas SB431542 only significantly downregulated the protein expression levels and secretion of TGF-β (P<0.05). Following c-Src knockdown, the protein expression levels of p-Src418, ALK5 and TGF-β were significantly decreased, the secretion of TGF-β was significantly suppressed (both P<0.05) and EMT was decreased in HLE-B3 cells. These results suggest that c-Src and TGF-β may promote EMT of LECs under HG conditions, with c-Src as the upstream regulatory molecule. Thus, the signal axis of c-Src/TGF-β in EMT of LECs may be a potential novel therapeutic target for the prevention of diabetic subcapsular cataract.

Abstract
IMPORTANCE Cataract risk factors data will provide epidemic evidence for cataract prevention. BACKGROUND This study aimed to study the risk factors for age-related cataract in a Chinese adult population. DESIGN This is a population-based, cross-sectional study. PARTICIPANTS A total of 10 234 eligible subjects ≥45 years old (response rate: 78.1%) were included in the study. METHODS We conducted detailed eye examinations including presenting visual acuity, best-corrected visual acuity, slit lamp examination of lens opacities and fundus examination. Questionnaires about lifestyle were administered. Measurements of blood pressure, heart rate and body mass index were collected. Serological metabolic indicators, including fasting blood glucose, triglycerides, cholesterol, lipoprotein, were also evaluated. We used stepwise multivariate logistic regression model to evaluate the association of these risk factors with any cataract and subtypes of cataract. MAIN OUTCOME MEASURES Odds ratios of risk factors for cataract were calculated. RESULTS For any cataract, we found age, gender (female), increased outdoor activity, no outdoor eye protection, high myopia, high low-density lipoprotein, low high-density lipoprotein, lower education level and increased pickled food intake were independent risk factors. When further examined the risk factors of different subtypes of cataract, we found that these risk factors also existed, but there were slight differences among different subtypes. In addition, for cortical cataract, lower annual family income and high diastolic pressure were additional independent risk factors. CONCLUSIONS AND RELEVANCE Reduced outdoor activity, outdoor eye protection, prevention of high myopia, higher education level, controlled blood pressure, improved high-density lipoprotein and low-density lipoprotein levels and reduced pickled food intake may help to reduce the risk of age-related cataract development.

Abstract
An estimated 95 million people worldwide are affected by cataract. Cataract still remains the leading cause of blindness in middle-income and low-income countries. With the advancement of surgical technology and techniques, cataract surgery has evolved to small-incisional surgery with rapid visual recovery, good visual outcomes, and minimal complications in most patients. With the development of advanced technology in intraocular lenses, the combined treatment of cataract and astigmatism or presbyopia, or both, is possible. Paediatric cataracts have a different pathogenesis, surgical concerns, and postoperative clinical course from those of age-related cataracts, and the visual outcome is multifactorial and dependent on postoperative visual rehabilitation. New developments in cataract surgery will continue to improve the visual, anatomical, and patient-reported outcomes. Future work should focus on promoting the accessibility and quality of cataract surgery in developing countries.

Abstract
Purpose We determined the age- and sex-specific prevalence of posterior subcapsular (PSC), nuclear, cortical, and mixed lens opacities in a population-based sample of Chinese-American adults. Methods A population-based sample of Chinese-Americans 50 years and older, from 10 census tracts in Monterey Park, CA, USA, underwent a detailed interview and a comprehensive clinical examination that included assessment of different types of lens opacities by the slit-lamp–based Lens Opacities Classification System II (LOCS II). All lens changes (including pseudophakia/aphakia), PSC, nuclear, and/or cortical opacities, were evaluated and graded. Results Of the 5782 eligible subjects, 4582 (79.2%) Chinese Americans aged 50 years and older completed a comprehensive eye examination. Of the participants with LOCS II grading (n = 4234/4582, 92%), 3.0% had PSC opacities, 38.1% had nuclear opacities, and 23.4% had cortical opacities. The prevalence of all lens changes was 48.0% for all age groups and was higher by 10-year increasing age groups (P < 0.0001). The prevalence of visual impairment in the better-seeing eye with cortical only, nuclear only, PSC only, and mixed opacities was 3.9%, 5.0%, 14.3%, and 9.4%, respectively. A total of 454 (9.9%) individuals had undergone cataract extraction in at least one eye. Conclusions Chinese Americans have a high prevalence of visual impairment associated with lens opacities, and a high prevalence of nuclear opacities. Public health policies and programs designed to improve cataract detection and treatment could help reduce the burden of visual impairment in Chinese Americans.

Antidepressants and risk of cataract development: A population-based, nested case-control study. J Affect Disord 2017; 215:237-244. [PMID: 28342338 DOI: 10.1016/j.jad.2017.03.044] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2017] [Revised: 03/13/2017] [Accepted: 03/17/2017] [Indexed: 11/22/2022]
Abstract
BACKGROUND Previous studies demonstrated increased risk of cataract development among users of selective serotonin reuptake inhibitors (SSRIs). However, it remains unknown whether this risk also prevails with the use of other types of antidepressants. The aim of this study was to investigate whether use of antidepressants is associated with an increased risk of cataract development. Moreover, the relationship between binding affinities of serotonin transporter (SERT) of antidepressant and the risk of cataracts is examined. METHODS We conducted a nested case-control study using National Health Insurance Research Database in Taiwan. A total of 14,288 patients were included; 7651 in the cataract group and 6637 in the control group. Antidepressant exposure was categorized by type, duration of use, and binding affinities of SERT. The association between antidepressant exposure and cataract development was assessed using conditional logistic regression analysis. RESULTS The adjusted odds ratios (AORs) for developing cataracts among continuous users of SSRIs, serotonin norepinephrine reuptake inhibitors (SNRIs), and other antidepressants were 1.26 (95% confidence interval (CI): 1.12-1.41, p<0.001), 1.21 (95% CI: 1.02-1.43, p=0.027), and 1.18 (95% CI: 1.04-1.34, p=0.009) respectively. Specifically, continuous uses of fluoxetine (AOR: 1.21; 95% CI: 1.01-1.46, p=0.042), fluvoxamine (AOR: 1.47; 95% CI: 1.01-2.12, p=0.043), venlafaxine (AOR: 1.44; 95% CI: 1.19-1.74, p<0.001) significantly increased the risk of cataract development. Moreover, continuous users of antidepressants with intermediate SERT binding affinities (AOR: 1.68; 95% CI: 1.10-2.56, p=0.017) were significantly associated with increased risks of cataract development. LIMITATIONS Several confounding factors such as obesity, multiple drug users, family history of cataracts, substance use, and environmental factors (such as sunlight or radiation exposure) were acquired. CONCLUSIONS We found increased risk of cataract development in patients continuously using antidepressants. Regular ocular evaluations in these patients are warranted.

Abstract
AIM To compare the potential protective effects of epi-gallocatechin gallate (EGCG) and ellagic acid (EA) in an experimental cataract model. METHODS Twenty-eight Spraque-Dawley rat pups were assigned into four groups. All the rats, except for those in the control group, were injected subcutaneously sodium selenite to induce experimental cataract on the postpartum ninth day, and between 10th and 14th days. Rats in the sham, EGCG, and EA groups were intraperitoneally administered 50 mg/(kg·d) saline solution, 50 mg/(kg·d) EGCG and 200 mg/(kg·d) EA, respectively. The reduced glutathione (GSH) and malondialdehyde (MDA) levels, total antioxidant status (TAS) and total oxidant status (TOS) in lens supernatants were measured. RESULTS The mean cataract gradings in EGCG and EA groups were found to be significantly lower than that in sham group (P<0.001). The mean GSH levels and TASs in EGCG and EA groups were significantly higher than that in sham group while mean MDA levels and TOSs in EGCG and EA groups were significantly lower than that in the sham group (P<0.001). CONCLUSION EGCG and EA have protective effects on cataract development via the inhibition of oxidative stress.

Abstract
OBJECTIVE Previous research has suggested a link between typical antipsychotic use and the development of cataracts, but the association between atypical antipsychotics and cataracts remains unclear in schizophrenia (SZ). METHODS A retrospective nested case-control study was conducted using data from the National Health Insurance Database of Taiwan between the year of 2000 and 2011. A total of 2144 SZ patients with cataracts and 2222 controls matched for age, sex, and index date were included. Antipsychotic exposure was categorized by type and duration, and the association between antipsychotic exposure and cataract development was assessed using a conditional logistic regression analysis. RESULTS We found that the severity of physical comorbidities, concurrent antidepressant use, and comorbidity with glaucoma or other retinal disorders were associated with an increased risk for cataract development. Alternatively, we did not find significant associations between continuous use of clozapine, risperidone, paliperidone, ziprasidone, olanzapine, quetiapine, amisulpride, zotepine or aripiprazole and risk of cataract development in SZ patients. CONCLUSIONS We did not detect any association between atypical antipsychotic use and risk of cataract development in SZ patients. Future studies with longitudinal ocular evaluations in patients using atypical antipsychotics are warranted to confirm our findings.

Abstract
Glaucoma is a leading cause of irreversible vision loss. Mental health and quality of life (QoL) are important issues for patients with glaucoma because visual impairment can be related to those. Analysis of mental health status or QoL in undiagnosed glaucoma patients can be free of the bias caused by awareness of the disease itself. In this study, the association between mental health status or QoL and undiagnosed glaucoma, along with the effects of visual acuity or visual field damage was investigated. Among individuals in the Korea National Health and Nutrition Examination Survey (KNHANES) V (2010-2012), subjects 40 years or older were included. KNHANES is a cross-sectional study using a stratified, multistage, probability sampling survey. The KNHANES includes questionnaires to assess psychological health, including depression, sleep duration, psychological stress, and suicidal ideations. To evaluate QoL, the KNHANES includes the EuroQoL, which is composed of a health-status descriptive system (EuroQol 5-dimension, EQ-5D) and the EQ visual analog scale (EQ-VAS). The proportion of people reporting symptoms of "some or severe problems" in all 5 dimensions of the EuroQoL-5 instrument, including anxiety/depression, was higher in the glaucoma group than in the nonglaucoma group. The subjective health status reported by the EQ-VAS was lower in the subjects with glaucoma than in those without glaucoma. Suicidal ideation was greater in subjects with glaucoma than in those without glaucoma (P = 0.005). After adjustment for demographic factors, glaucoma subjects were more likely than those without glaucoma to have some or severe problems with anxiety/depression (odds ratio 1.77; 95% confidence interval, 1.26-2.49). Worse best corrected visual acuity was associated with more problems with a lower EQ-5D score in glaucoma subjects. Individuals who had undiagnosed glaucoma were more depressed than those without glaucoma. QoL can be affected by glaucoma, especially in patients with worse visual acuity.

Abstract
Metabolic syndrome is becoming a worldwide medical and public health challenge as it has been seen increasing in prevalence over the years. Age-related eye diseases, the leading cause of blindness globally and visual impairment in developed countries, are also on the rise due to aging of the population. Many of the individual components of the metabolic syndrome have been shown to be associated with these eye diseases. However, the association of metabolic syndrome with eye diseases is not clear. In this review, we reviewed the evidence for associations between metabolic syndrome and certain ocular diseases in populations. We also reviewed the association of individual metabolic syndrome components with ocular diseases due to a paucity of research in this area. Besides, we also summarised the current understanding of etiological mechanisms of how metabolic syndrome or the individual components lead to these ocular diseases. With increasing evidence of such associations, it may be important to identify patients who are at risk of developing metabolic syndrome as prompt treatment and intervention may potentially decrease the risk of developing certain ocular diseases.

Abstract
Background The occurrence and severity of corneal oedema after phacoemulsification is dependent on the integrity of corneal endothelial cells. The function of these cells is affected by diabetes mellitus and consequently the behaviour of the cornea in diabetic patients is of special interest. Aim To compare the frequency of corneal oedema in two age-matched groups of diabetics and non diabetic patients that underwent cataract surgery in the Ophthalmology Department of Xanthi General Hospital in Greece. Methods A retrospective case control study was conducted in a retrospective fashion. Patients in the control and study groups were assessed regarding the severity of corneal oedema at three postoperative visits: days 1, 3–7, 10–14 after the operation. Ultrasound energy consumed during phacoemulsification was also a parameter of interest and possible correlations with the pre-existent cataract severity and the subsequent incidence of corneal oedema were investigated. Results The difference in the incidence of severe corneal oedema between the study and control group was statistically significant: (4.5% non diabetics vs 14.3% diabetics). The consumed ultrasound energy did not define final clinical outcome. Conclusions The existence of diabetes mellitus type 2 appears to be a significant risk factor for the development of persistent corneal oedema. The results of our study led to the modification of the algorithm for postoperative follow-up of patients of this remote area of Greece. Ultrasound energy is not the only defining factor for the development of corneal oedema. Persistent corneal oedema is more frequent in diabetic patients 2 weeks postoperatively. Modern Greek public health system requires modifications in clinical governance issues.

BACKGROUND The aim of this study is to report the 6-year incidence of age-related cataract in a population-based study. DESIGN The design used is a population-based cohort study. PARTICIPANTS A cohort of 2484 phakic subjects, aged 40 years and above at baseline, from a south Indian population was included in the study. METHODS Bilateral phakics with visual acuity of 6/12 or better and cataract less than N2, C2 and P2 on the Lens Opacities Classification System II at baseline were included. Subjects with glaucoma and corneal or retinal diseases were excluded. Incident visually significant cataract was defined as visual acuity of less than 6/18 with a corresponding one grade or greater change in Lens Opacities Classification System II or history of having undergone cataract surgery with evidence of pseudophakia or aphakia at the 6-year follow-up. MAIN OUTCOME MEASURES Six-year incidence of visually significant cataract and associated risk factors data were collected. RESULTS Incident visually significant cataract at 6 years was seen in 158 subjects (6.36%, 95% CI: 5.40-7.32, phakics:pseudophakics/aphakics 70:88). Incidence was higher in the rural cohort as compared with the urban cohort (P < 0.001). Incidence increased with age and was highest in the ≥70 years age group (odds ratio (OR):31.23, 95% CI: 15.20-64.16, P < 0.001). Other associated risk factors included illiteracy (OR 1.75, 95% CI: 1.17-2.61, P = 0.007) and smoking (OR 1.77, 95% CI: 1.08-2.88, P = 0.02). CONCLUSIONS A significant proportion of the population developed visually significant age-related cataract at 6 years. Incident visually significant cataract was significantly greater for the rural cohort between 50 and 69 years old.

[PMID: 26284359 PMCID: PMC4540437 DOI: 10.1371/journal.pone.0135870] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2015] [Accepted: 07/27/2015] [Indexed: 01/15/2023] Open
Abstract
Purpose To study the relationship between outdoor activity and risk of age-related cataract (ARC) in a rural population of Taizhou Eye Study (phrase 1 report). Method A population-based, cross-sectional study of 2006 eligible rural adults (≥45 years old) from Taizhou Eye Study was conducted from Jul. to Sep. 2012. Participants underwent detailed ophthalmologic examinations including uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), intraocular pressure (IOP), slit lamp and fundus examinations as well as questionnaires about previous outdoor activity and sunlight protection methods. ARC was recorded by LOCSⅢ classification system. The prevalence of cortical, nuclear and posterior subcapsular cataract were assessed separately for the risk factors and its association with outdoor activity. Results Of all 2006 eligible participants, 883 (44.0%) adults were diagnosed with ARC. The prevalence rates of cortical, nuclear and posterior subcapsular cataract per person were 41.4%, 30.4% and 1.5%, respectively. Women had a higher tendency of nuclear and cortical cataract than men (OR = 1.559, 95% CI 1.204–2.019 and OR = 1.862, 95% CI 1.456–2.380, respectively). Adults with high myopia had a higher prevalence of nuclear cataract than adults without that (OR = 2.528, 95% CI 1.055–6.062). Multivariable logistic regression revealed that age was risk factor of nuclear (OR = 1.190, 95% CI 1.167–1.213) and cortical (OR = 1.203, 95% CI 1.181–1.226) cataract; eyes with fundus diseases was risk factor of posterior subcapsular cataract (OR = 6.529, 95% CI 2.512–16.970). Outdoor activity was an independent risk factor of cortical cataract (OR = 1.043, 95% CI 1.004–1.083). The risk of cortical cataract increased 4.3% (95% CI 0.4%-8.3%) when outdoor activity time increased every one hour. Furthermore, the risk of cortical cataract increased 1.1% (95% CI 0.1%-2.0%) when cumulative UV-B exposure time increased every one year. Conclusion Outdoor activity was an independent risk factor for cortical cataract, but was not risk factor for nuclear and posterior subcapsular cataract. The risk of cortical cataract increased 4.3% when outdoor activity time increased every one hour. In addition, the risk of cortical cataract increased 1.1% (95% CI 0.1%-2.0%) when cumulative UV-B exposure time increased every one year.

Childbearing May Increase the Risk of Nondiabetic Cataract in Chinese Women's Old Age. J Ophthalmol 2015; 2015:385815. [PMID: 26351572 PMCID: PMC4553188 DOI: 10.1155/2015/385815] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2015] [Revised: 07/23/2015] [Accepted: 07/30/2015] [Indexed: 12/02/2022] Open
Abstract
Backgrounds. Ocular changes may arise during pregnancy and after childbirth, but very few studies have reported the association between childbearing and cataract among older adults. Methods. 14,292 individuals aged 60+ years were recruited in Xiamen, China, in 2013. Physician-diagnosed cataract and diabetes status were assessed by a self-reported questionnaire. Childbearing status was measured by number of children (NOC). Structural equation modeling (SEM) analysis was conducted to examine the relationships among NOC, diabetes, and cataract. Gender-specific logistic models regressing nondiabetic cataract on NOC were performed by adjusting some covariates. Results. 14,119 participants had complete data, of whom 5.01% suffered from cataract, with higher prevalence in women than men (6.41% versus 3.51%). Estimates of SEM models for women suggested that both NOC and diabetes were risk factors for cataract and that no correlation existed between NOC and diabetes. Women who had one or more children faced roughly 2–4 times higher risk of nondiabetic cataract than their childless counterparts (OR [95% CI] = 3.88 [1.24, 17.71], 3.21 [1.04, 14.52], 4.32 [1.42, 19.44], 4.41 [1.46, 19.74], and 3.98 [1.28, 18.10] for having 1, 2, 3, 4-5, and 6 or more children, resp.). Conclusions. Childbearing may increase the risk of nondiabetic cataract in Chinese women's older age.

Abstract
AIM To evaluate the visual outcome and factors influencing visual outcome of manual small incision cataract surgery (MSICS) in the rural area in the Xianfeng County. METHODS Eighty-two eyes of 82 patients who underwent cataract surgery performed by using MSICS technique were identified. Data collected included each patient's age, gender, the level of education. Uncorrected and corrected distance visual acuity (UDVA and CDVA) at presentation and at 1, 6, 8wk postoperatively, pre-existing eye disease, operative findings and complications, the risk factors were evaluated. RESULTS In 82 patients, the average age was 69.6±0.6y, illiterate were 52 (63.4%). Of 82 eyes, pseudophakia was present in 77 eyes (93.9%). At 1wk postoperatively, 47 eyes (57.3%) had the UDVA of ≥6/18, and 52 eyes (63.4%) had the CDVA of ≥6/18. At 6 to 8wk postoperatively, 50 eyes (61.0%) had UDVA of ≥6/18, and 57 eyes (69.5%) had the CDVA of ≥6/18. Postoperative visual status was significantly related to the co-morbidities, such as corneal pathology, glaucoma (P<0.001). Operative complications, such as posterior capsule opacity and cystoid macular edema were main operative cause for the poor visual outcome. CONCLUSION MSICS provides a good visual recovery in our study but the vision outcome did not fulfill the standards proposed by WHO, which highlights the need for an improvement in local socioeconomic understanding, population education and surgery quality.

Abstract
PURPOSE To describe a new association between nonsenile nuclear cataracts and pigmentary glaucoma in patients with controlled intraocular pressure (IOP). DESIGN Retrospective consecutive case series of nonsenile nuclear cataracts seen in patients with pigmentary glaucoma with controlled IOP in a single glaucoma specialist practice. Eight eyes of 7 patients with pigmentary glaucoma and visually significant cataract who underwent cataract removal were reviewed. RESULTS Patients with pigmentary glaucoma developed rapidly progressing, nonsenile nuclear cataracts, with resulting myopic shifts between 4 and 13 D from baseline in <2 years. The patients had controlled IOP and there were no associations between medication use and cataract development. CONCLUSIONS A new association between pigmentary glaucoma and nonsenile nuclear cataracts is described. In these patients, the IOP remains controlled and no association is seen between the cataract and medication use. The cataract is rapidly progressive and can cause a myopic shift between 4 and 13 D. Awareness of the purely nuclear cataract and its' clinical presentation can assist the clinician when approaching the patient with pigment dispersion and decreasing vision. To the best of our knowledge, this is a new association and warrants further investigation.

Abstract
Background Cataract is the major cause of blindness across the world. Many epidemiologic studies indicated that hypertension might play an important role in the development of cataract, while others not. We therefore conducted this meta-analysis to determine the relationship between risk of cataract and hypertension. Methods Retrieved studies on the association of hypertension with cataract risk were collected from PubMed, Web of Science and the Cochrane Library during June 2014 and were included into the final analysis according to the definite inclusion criteria. Odds ratio (OR) or risk ratio (RR) were pooled with 95% confidence interval (CI) to evaluate the relationship between hypertension and cataract risk. Subgroup analyses were carried out on the basis of cataract type, race and whether studies were adjusted for main components of metabolic syndrome (MS). Results The final meta-analysis included 25 studies (9 cohort, 5 case-control and 11 cross-sectional) from 23 articles. The pooled results showed that cataract risk in populations with hypertension significantly increased among cohort studies (RR 1.08; 95% CI: 1.05–1.12) and case-control or cross-sectional studies (OR 1.28; 95% CI: 1.12–1.45). This association was proved to be true among both Mongolians and Caucasians, and the significance was not altered by the adjustment of main components of MS. Subgroup analysis on cataract types indicated that an increased incidence of posterior subcapsular cataract (PSC) resulted among cohort studies (RR 1.22; 95% CI: 1.03–1.46) and cross-sectional/case-control studies (OR 1.23; 95% CI: 1.09–1.39). No association of hypertension with risk of nuclear cataract was found. Conclusions The present meta-analysis suggests that hypertension increases the risk of cataract, especially PSC. Further efforts should be made to explore the potential biological mechanisms.

Abstract
Background Prolong sitting has been found associated with metabolic disorders. Little is known about the self-reported cataract status in general population of Taiwan, not to mention its relation to prolong sitting. We aimed to examine the prevalence of cataract between 2001 and 2013 in Taiwan and to the association between prolonged sitting and cataract. Methods We used three data sets with those aged 40 years and older from the National Health Interview Survey (NHIS) from 2001 (n = 8334), 2009 (n = 11207), and 2013 (n = 10940). Subsequent statistical analyses involved chi-square test, t test, and logistic regression modeling. SUDAAN was used to account for sampling scheme. Results The prevalence of cataract ranged from 10.7% in 2001, 13.13% in 2009, to 11.84% in 2013. Participants who sat for more than 7 hours per day had a significantly higher risk of cataract (OR = 1.20, CI = (1.04-1.39)) compared with those who sat for fewer than 3 hours per day after controlling for age and other risk factors like being older or female, lower education level, not being currently employed, living in a highly urbanized area, having hypertension, diabetes, myopia, and being an former smoker (compared to a never smoker). Conclusion Increased daily sitting time was associated with cataract, especially for people who sat more than 7 hours per day.

Abstract
Cataract is the most common ocular damage in systemic lupus erythematosus (SLE). We analyzed data from the Hopkins Lupus Cohort longitudinally to identify the factors that predict onset of cataract prior to 60 years of age. The Hopkins Lupus Cohort is a clinical cohort of patients with SLE seen quarterly. This analysis was based on the follow-up experience prior to age 60 of 2,109 SLE patients who had not had a cataract prior to cohort entry. Patients saw their ophthalmologist every 6 months. Cataract was defined by the SLICC/American College of Rheumatology Damage Index. The rate of incident cataract was calculated in subsets of the follow-up defined by patient characteristics and history. Multivariable logistic regression models were fit to identify predictors of cataract while controlling for potential confounding variables. The analysis was based on 11,887 persons-years of follow-up, with median follow-up time of 4.1 years per patient. The incidence of cataract was 13.2/1,000 persons-years. Adjusting for other predictors, a cumulative prednisone dose equivalent to 10 mg/day for 10 years was a strong predictor of cataract (RR = 2.9, P = 0.0010). Disease activity measured by SELENA-SLEDAI (P = 0.0004) and higher systolic blood pressure (P = 0.0003) were associated with cataract. Duration of SLE, diabetes mellitus, smoking, cholesterol, renal involvement, immunological profile and medication history other than prednisone were not associated with cataract. Cataract development in SLE patients is multifactorial with prednisone, systolic blood pressure and disease activity all playing a role.

Abstract
PURPOSE To evaluate refractive changes after lens-sparing vitrectomy for rhegmatogenous retinal detachment (RD). DESIGN Retrospective case series. METHODS A retrospective chart review was conducted in 66 eyes of 66 patients (50.0 ± 9.9 years old) who had undergone lens-sparing vitrectomy for rhegmatogenous RD. Spherical equivalent refractive power was evaluated before and 1, 2, 3, 6, 9, 12, and 15 months after vitrectomy. The relation between refractive changes and several parameters was investigated, such as axial length, presence of preoperative hemorrhage, preoperative spherical equivalent, retinal tear size, logMAR best-corrected visual acuity, number of laser photocoagulations, occurrence of postoperative vitreous hemorrhage, and degree of postoperative inflammatory reaction. Surgical parameters examined included operative time, wide-angle viewing system use, intraoperative adjuvant and gas tamponade use, vitrectomy system gauge, and surgeon. RESULTS Significant and continuous myopic shift was observed after vitrectomy throughout the study period. Spherical equivalent was not significantly different between the operated eyes and the fellow control eyes until 3 months after vitrectomy, but the operated eyes were significantly more myopic at 3 months and later postoperatively (P < .05). Of the 58 eyes finally included (8 patients lost to follow-up), 27 (47%) underwent cataract surgery after vitrectomy. Patients who underwent cataract surgery were significantly older than those who did not (P < .05); no other examined parameter was significantly different between groups. CONCLUSIONS A significant myopic progression occurred in eyes after lens-sparing vitrectomy for rhegmatogenous RD. A considerable amount of anisometropia occurred, even in the early postoperative period. Patient age was the only risk factor with the potential to advance the nuclear sclerotic cataract progression after vitrectomy.

Abstract
BACKGROUND In the context of population aging, visual impairment has emerged as a growing concern in public health. However, there is a need for further research into the relationship between visual impairment and chronic medical conditions in the elderly. The aim of our study was to examine the relationship between visual impairment and three main types of co-morbidity: chronic physical conditions (both at an independent and additive level), mental health and cognitive functioning. METHODS Data were collected from the COURAGE in Europe project, a cross-sectional study. A total of 4,583 participants from Spain were included. Diagnosis of chronic medical conditions included self-reported medical diagnosis and symptomatic algorithms. Depression and anxiety were assessed using CIDI algorithms. Visual assessment included objective distance/near visual acuity and subjective visual performance. Descriptive analyses included the whole sample (n = 4,583). Statistical analyses included participants aged over 50 years (n = 3,625; mean age = 66.45 years) since they have a significant prevalence of chronic conditions and visual impairment. Crude and adjusted binary logistic regressions were performed to identify independent associations between visual impairment and chronic medical conditions, physical multimorbidity and mental conditions. Covariates included age, gender, marital status, education level, employment status and urbanicity. RESULTS The number of chronic physical conditions was found to be associated with poorer results in both distance and near visual acuity [OR 1.75 (CI 1.38-2.23); OR 1.69 (CI 1.27-2.24)]. At an independent level, arthritis, stroke and diabetes were associated with poorer distance visual acuity results after adjusting for covariates [OR 1.79 (CI 1.46-2.21); OR 1.59 (CI 1.05-2.42); OR 1.27 (1.01-1.60)]. Only stroke was associated with near visual impairment [OR 3.01 (CI 1.86-4.87)]. With regard to mental health, poor subjective visual acuity was associated with depression [OR 1.61 (CI 1.14-2.27); OR 1.48 (CI 1.03-2.13)]. Both objective and subjective poor distance and near visual acuity were associated with worse cognitive functioning. CONCLUSIONS Arthritis, stroke and the co-occurrence of various chronic physical diseases are associated with higher prevalence of visual impairment. Visual impairment is associated with higher prevalence of depression and poorer cognitive function results. There is a need to implement patient-centered care involving special visual assessment in these cases.

Abstract
There is evidence from epidemiologic data that cataract is more common in women than men. This is not solely due to a higher rate of cataract extraction in women, as is the case in the western world, but several population-based studies show that females have a higher prevalence of lens opacities, especially cortical. There is no firm evidence that lifestyle-related factors are the cause of this gender discrepancy. Focus has therefore been directed towards the role of estrogen in cataract formation. Although data on endogenous and exogenous estrogen involvement in cataractogenesis are conflicting, some studies have indicated that hormone therapy may decrease the risk of cataract and thus be protective. It has been hypothesized that the decrease in estrogen at menopause cause increased risk of cataract in women, i.e. not strictly the concentration of estrogen, but more the withdrawal effect. Estrogens are known to exert several anti-aging effects that may explain the longer lifespan in women, including metabolically beneficial effects, neuroprotection, preservation of telomeres and anti-oxidative properties. Since oxidative stress is considered important in cataractogenesis, studies have investigated the effects of estrogens on lens epithelial cells in culture or in animal models. Several investigators have found protection by physiological concentrations of 17β-estradiol against oxidative stress induced by H2O2 in cultured lens epithelial cells. Although both main types of estrogen receptors, ERα and ERβ, have been demonstrated in lens epithelium, most studies so far indicate that the estrogen-mediated protection in the lens is exerted through non-genomic, i.e. receptor-independent mechanisms, possibly through phosphorylation of extracellular signal-regulated kinase (ERK1/ERK2), a member of the mitogen-activated protein kinase (MAPK)-signaling pathway. Further studies are needed, both epidemiologic as to the role of hormone therapies, and laboratory studies regarding molecular estrogen-mediated mechanisms, in order to comprehend the role of estrogens on cataract formation.

Prevalence of and risk factors for age-related and anterior polar cataracts in a Korean population. PLoS One 2014; 9:e96461. [PMID: 24936893 PMCID: PMC4060994 DOI: 10.1371/journal.pone.0096461] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2013] [Accepted: 04/09/2014] [Indexed: 11/19/2022] Open
Abstract
Objective To investigate the potential risk factors associated with nuclear, cortical, posterior subcapsular, and anterior polar cataracts (APC) in the Korean population. Research Design and Methods This was a population-based, cross-sectional study of 7992 adults (over 40 years of age) from the data of the fourth annual Korea National Health and Nutrition Examination Survey, performed from 2007 to 2009. The presence of lens opacity was examined by slit-lamp biomicroscopy and evaluated according to LOCS II standard photographs. The subtype of cataract present, including nuclear, cortical, posterior subcapsular, and anterior polar cataracts, was noted. Multivariable adjusted logistic regression analysis was conducted to examine the odds ratio (OR) and 95% confidence interval (CI) for association of each specific type of cataract with age, sex, health examination, and medical history. Results The prevalence of nuclear, cortical, and posterior subcapsular cataract increased gradually with increasing age. However, the prevalence of APC peaked in the 50- to 59-year-old subjects. All types of cataract except for APCs were more prevalent in women. Oral steroid use was associated with a lower risk of APC. Conclusions These findings showed the unique characteristics of APC in the Korean population.

Prevalence of and factors associated with lens opacities in a Korean adult population with and without diabetes: the 2008-2009 Korea National Health and Nutrition Examination Survey. PLoS One 2014; 9:e94189. [PMID: 24718421 PMCID: PMC3981769 DOI: 10.1371/journal.pone.0094189] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2014] [Accepted: 03/10/2014] [Indexed: 11/18/2022] Open
Abstract
Objective We examined the prevalence of and factors associated with lens opacities in a Korean adult population with and without diabetes. Research Design and Methods Among the 11,163 adults (≥19 years old) from the fourth Korea National Health and Nutrition Examination Survey in 2008–2009, the data from laboratory tests, nutritional surveys, and slit-lamp examinations of 10,248 persons (4,397 men, 5,851 women) were examined. Cataract was defined as the presence of any nuclear, cortical, subcapsular, or mixed cataract in at least one eye, using the Lens Opacities Classification System III. Results The weighted prevalence of cataracts were 23.5% [95% confidence interval (CI), 21.7–25.4] in a Korean adult population (19–39 years old, 1.8% [1.3–2.5], 40–64 years old, 25.2% [22.5–28.1],≥65 years old, 87.8% [85.4–89.9])and 54.7% [50.1–59.2] in a diabetic population(19–39 years old, 11.6% [4.5–26.5], 40–64 years old, 41.1% [35.4–47.0], ≥65 years old, 88.3% [83.5–91.8]). In a logistic regression analysis, age, myopia, and the presence of diabetes were independent risk factors. For young (age 19–39 years) and middle aged (age 40–65 years) adults with diabetes, the OR of having a lens opacity is 5.04 [1.41–17.98] and 1.47 [1.11–1.94], respectively, as those without diabetes, whereas for adults aged 65 and older, there was no difference in the prevalence of cataract. Conclusions According to these national survey data, ∼ 24% of Korean adults and ∼ 55% of people with diabetes have cataracts. The presence of diabetes was independently associated with cataracts in young and middle aged adults.

[PMID: 24410920 PMCID: PMC3928645 DOI: 10.1186/1471-2415-14-4] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2013] [Accepted: 01/02/2014] [Indexed: 11/15/2022] Open
Abstract
Background To assess the socio-demographic and health-related risk factors associated with cataract subtypes in Korea. Methods A total of 11,591 participants (aged ≥40 years) were selected from the Korean National Health and Nutrition Examination Survey between 2008 and 2010. The Korean Ophthalmologic Society conducted detailed ophthalmologic examinations on these participants based on the Lens Opacity Classification System III. Risk factors for developing any type of cataract, and its subtypes (nuclear, cortical, posterior subcapsular and mixed), were identified from univariate and multivariate logistic regression analysis. Results The prevalence of cataracts was 40.1% (95% CI, 37.8 − 42.3%) in participants over 40 years old. Older age, lower monthly household income, lower education, hypercholesterolemia, hypertension, and diabetes mellitus (DM) were independent risk factors for development of any cataract. Older age, lower monthly household income, lower education, hypercholesterolemia, and DM were independent risk factors for development of pure cortical cataracts. Older age, lower education, metabolic syndrome, and DM were independent risk factors for development of pure nuclear cataracts. Older age and DM were independent risk factors for development of pure posterior subcapsular cataracts. Older age, lower monthly household income, lower education, and DM were independent risk factors for development of mixed cataracts. Conclusion Although socioeconomic disparities are related to cataract development, this study identified several “modifiable” risk factors that may help to lower the incidence of cataracts and associated vision loss. Improved control of blood pressure, blood, glucose, and cholesterol may help to reduce the incidence of cataracts in the general Korean population.
