Awareness of eye complications and prevalence of retinopathy in the first visit to eye clinic among type 2 diabetic patients

Awareness of Diabetic Retinopathy Among Patients With Type 2 Diabetes Mellitus in Primary Healthcare Centers in Madinah, Saudi Arabia: A Cross-Sectional Study

Background The prevalence of diabetes mellitus (DM) in Saudi Arabia is among the highest in the Middle East and North Africa (MENA) regions. Various complications of DM can cause problems in the long term. One of the most prevalent microvascular problems and the primary cause of blindness is diabetic retinopathy (DR), and a significant proportion of the population with diabetes eventually develop diabetes retinopathy. Recognizing and understanding DR may be crucial for patients in identifying and averting this complication.  Objectives The objective of this atudy is to assess the awareness of DR among patients with type 2 DM at primary healthcare centers in Madinah, Saudi Arabia.  Methods This cross-sectional study involved a survey of patients with diabetes who attended Madinah primary care clinics between August and September 2023. The study was conducted in Madinah, Saudi Arabia, from May to November 2023.  Results A total of 240 patients participated with a median age of 49.7 years and a gender distribution of 121 (50.4%) men. Overall, less than half of patients had a fair level of knowledge (47.1%) and a good level of knowledge (42.1%) about DR, whereas 10.8% had poor knowledge. Physicians were the primary source of information for patients, followed by the internet, family, and friends. Higher levels of education, diabetes that had been present for a longer period, and regular eye exams were associated with better understanding. This study emphasizes the importance of improving patient knowledge and awareness of DR.  Conclusions We observed a high level of awareness of DR among participants. Furthermore, higher awareness was associated with longer disease duration and compliance with diabetes treatment.

Determination of Factors Influencing the Health Belief Model (HBM) and Adherence to Intravitreal Anti-vascular Endothelial Growth Factor (VEGF) Among Patients With Diabetic Macular Edema (DME)

Background Diabetic macular edema (DME) is becoming one of the leading causes of blindness worldwide with a significant impact on quality of life. The effectiveness of intravitreal (IVT) anti-vascular endothelial growth factor (VEGF) therapy has been established by clinical trials and has become the treatment of choice in the majority of DME patients in reducing macular edema and improving visual acuity. Frequent drop-out and discontinuation of treatment are major issues. Lack of compliance can lead to worsening outcomes and be a burden to patients and the healthcare system. Purpose The purpose of this study is to assess multiple factors that affect adherence to IVT anti-VEGF treatment among patients with DME, including socioeconomic causes and the Health Belief Model (HBM) domains, in addition to exploring the relationship between them. Methods This cross-sectional study was conducted among DME patients in Hospital Canselor Tuanku Muhriz, Kuala Lumpur, Malaysia, from December 2020 to June 2021. We identified eligible patients using a retrospective chart review of clinical findings and optical coherence tomography (OCT) findings. Included subjects were of Malaysian nationality, aged 18 years and above, who were initiated or re-initiated IVT anti-VEGF treatment regime and on follow-up for at least six months from initial injection from January 2019 onwards. A translated and validated self-administered questionnaire was given to the respondents. Data were analyzed using IBM SPSS Statistics for Windows, Version 26.0 (Released 2019; IBM Corp., Armonk, New York, United States). Demographics of the patient were summarized using descriptive statistics, independent sample t-test was used to compare the difference in components of the HBM questionnaire. Linear regression was further used to explore the relationship between patients' demographics and the HBM component. Results A total of 141 patients participated in this study, of whom 56.2% patients were adherent to treatment. The majority were aged 60 years and above (56.7%), male (52.5%), Malay (38.9%), and married (71.6%). There was a significant statistical difference in patients who were adherent to treatment, in terms of life entourage (p=0.004, Fisher Exact test). HBM domains that influenced adherence to treatment included perceived severity, perceived barriers, perceived benefits, cues to action, and self-efficacy (p<0.05, independent sample t-test). Further, multiple logistic regression tests on sociodemographic factors and HBM domains after eliminating confounding factors narrowed down the significant variables to perceived susceptibility (p= 0.023), perceived benefits (p< 0.001), and self-efficacy (p< 0.001). Conclusion Patients' adherence to IVT anti-VEGF is influenced by perceived susceptibility to complications from DME, perceived benefits to the treatment, and self-efficacy.

An Assessment on the Awareness of Diabetic Retinopathy Among Participants Attending the Diabetes Awareness Camp in Saudi Arabia

Aim The objective of this study is to assess the level of awareness of the effect of diabetes and diabetic retinopathy (DR) on the eye among a sample of the Jeddah community. Methods A cross-sectional study was conducted among those attending a diabetes awareness camp in Jeddah, Saudi Arabia, in November 2021. Participants were asked to answer questions in a structured questionnaire that was already used in a previous study. Responses were analyzed using Statistical Package for the Social Sciences (SPSS) version 25 (IBM SPSS Statistics, Armonk, NY, USA). Results A total of 352 participants were included in this study, 184 (52.3%) of them were females. Of the participants, only 74 (21%) had diabetes mellitus (DM). The vast majority (94%) of the participants believed that diabetes could affect the eyes, and 94.3% believed that maintaining the level of blood sugar could maintain the eye and the level of vision. Moreover, 77.3% were aware that diabetes could lead to visual impairment and blindness. Around one-third of the total participants and less than half of the diabetic group were found familiar with DR. Although 96% of diabetic participants reported the need for diabetics to get their eyes checked annually, only 70% did so. Lack of awareness of the effect of diabetes on the retina was the main barrier preventing diabetic groups from getting their eye checked. Conclusion Despite the good level of awareness among the community and diabetics about diabetes and its effect on the eyes, there is less awareness that DR is one of the most dangerous complications that lead to visual impairments. These findings assure the importance to raise awareness of DR among the community and diabetics and increase awareness of the importance of annual eye examinations.

Awareness of Diabetic Retinopathy Among Patients With Type 2 Diabetes Attending the Outpatient Clinic in the General Hospital in Rabigh, Saudi Arabia: A Cross-Sectional Study

Introduction: Diabetic retinopathy (DR) is a common microvascular complication of type 2 diabetes (T2D) and a major cause of blindness. DR awareness is important for early identification and management in patients with T2D. This study aimed to estimate the level of awareness of DR and its risk factors among patients with T2D in Saudi Arabia.

Methods: We conducted a cross-sectional study to analyze data collected from 291 patients with T2D attending outpatient clinics in the General Hospital in Rabigh during 2020-2021. We collected demographic information and level of awareness about T2D and DR.

Results: Among 291 patients with T2D, 42.3% had T2D for more than five years, and 37.8% had T2D for two to five years. In our study population, 32.3% of participants obtained high school education, and 42.3% had moderate income. Over half of respondents (56.4%) had their last eye exam within the past year, and 68.4% of participants believed high blood glucose levels might cause vision problems. The mean ± standard deviation of the DR awareness score was 7.23 ± 2.74. Most participants had moderate level of awareness (39.5% of participants), 31.6% had good level of awareness, and 28.9% had poor level of awareness about T2D and DR. Participants without DR or who had DR for less than two years and those who had their eyes checked by a doctor last year had a significantly higher DR awareness level. 

Conclusion: We asked patients with T2D to assess their level of DR awareness. Most patients had moderate awareness levels, indicating a need for improved awareness of T2D complication on retina and treatment options. Patients should also be motivated for retinal screening to reduce the risk of visual complications. Furthermore, DR screening programs should not be limited to eye care centers. Improved awareness and access to screening programs will help patients and their healthcare providers achieve optimal outcomes in prevention of DR.

Is the Duration of Diabetes Diseases Positively Associated With Knowledge About Diabetic Complications? Knowledge of Diabetes Mellitus Complications and Associated Factors Among Type-2 Diabetic Patients in Public Hospitals of Addis Ababa, 2020

Background

Although the importance of educational programs in the prevention and control of diabetes mellitus (DM) and its complication is well-recognized, there are concerns about whether these programs are achieving the desired goal of increasing knowledge of DM and its complication in developing countries. Therefore, this study assessed knowledge of DM complications and associated factors among type-2 diabetic patients in public hospitals of Addis Ababa.

Method

Simple random sampling technique was used to select 422 participants. Data were entered to EpiData Version 4.6.0.1 and analyzed using SPSS Version 25 software. Multicollinearity and model goodness-of-fit was checked. A multivariate logistic regression model at 95% CI was used to identify the predictors.

Result

The overall knowledge of diabetes complications among diabetic patients in the Hospitals of Addis Ababa was 54.9%. In the fitted model, being a profession of governmental workers [adjusted odds ratio (AOR) = 3.12, 95% CI (1.33, 7.34)] and merchants [AOR = 2.54, 95% CI (1.16, 5.56)]; DM duration 5–10 years [AOR = 0.41, 95% CI (0.23, 0.73)] and ≥10 years [AOR = 0.36, 95% CI (0.19, 0.69)]; family history of DM [AOR = 1.68, 95% CI (1.03, 2.75)]; and participating in diabetic counseling [AOR = 2.41, 95% CI (1.50, 3.86)] were significantly associated with knowledge about DM complications.

Conclusion and Recommendation

The overall knowledge of diabetes complications among diabetic patients in the Hospitals of Addis Ababa was 54.9%. It was determined by the duration of DM, current profession, family history, and participation in diabetes counseling. Hence, emphasis on sustaining knowledge about diabetes complications for patients who are more than 5 years since diagnosis and attention is needed about knowledge diabetic farmers.

Diabetic retinopathy awareness and eye care behaviour of indigenous women in Saskatoon, Canada

Diabetes is a public health challenge in Canada with a disproportionate number of Indigenous people, especially women, living with diabetes. Diabetic retinopathy is a diabetes ocular complication and a common cause of blindness in Canadian adults. Many individuals living with diabetes do not have regular diabetic eye screening. This study sought to determine the diabetic retinopathy awareness and eye care behaviour of Indigenous women with diabetes or at risk of diabetes. This was a quantitative study among 78 Indigenous women (First Nations and Métis) in Saskatoon, Canada. Data on diabetic retinopathy awareness and eye care behaviour were collected via a knowledge, attitude, and practice survey. Participants had high diabetic retinopathy practice mean scores (32.16) than knowledge (30.16) and attitude scores (22.56). Sub-group analysis showed a significant difference in knowledge scores between age, education, and diabetes status, and differences in practice scores between age and education. Although our regression analysis indicated an association between education and knowledge scores (p = 0.024), and diabetes status and attitude scores (p = 0.044), the associations are not conclusive. Indigenous peoples with or at risk of diabetes may benefit from targeted interventions on diabetes and eye care, which could improve eye care awareness and behaviour.

Awareness of diabetic retinopathy among patients with type 2 diabetes mellitus in Qassim, Saudi Arabia

Introduction:

Diabetic retinopathy (DR) is a well-known complication of diabetes mellitus (DM) and a major cause of vision loss. Increased awareness of DR is crucial for the prevention and early diagnosis of the disease and preservation of vision. The objective of this study is to assess the level of DR awareness in the Qassim region among type 2 diabetic patients.

Materials and Methods:

A cross-sectional study was conducted among patients who visited diabetic clinics between January and March 2019 in the Qassim region, Saudi Arabia. This study used structured questionnaires to assess awareness and knowledge of DR. The patients were considered to have a good level of DR awareness if they answered more than 60% of the questions correctly.

Results:

A total of 307 patients with type 2 DM, 201 males (65.5%) and 106 females (34.5%), participated in the current study. The results revealed that 63.5% of the participating patients involved in this study had good knowledge about DR; 86% of the patients had knowledge about the correlation between retinopathy and DM, and 89.9% believed that DR can be prevented by good control of diabetes.

Conclusion:

The study showed that about two-thirds of the participants were aware of DR, and most of them had knowledge about the relationship between retinopathy and DM. Younger patients and the group with a higher level of education were found to be more aware of DR. Awareness of DR should be correlated with behavioral practices to improve a patient's compliance in attending annual eye examinations.

Diabetic retinopathy screening barriers among Palestinian primary health care patients: a qualitative study

PURPOSE

Diabetic Retinopathy (DR) screening among Palestinian diabetic patients is limited. To improve the care of our patients, we explored the barriers to DR screening with a qualitative study.

METHODS

Three focus groups were conducted in the northern West Bank. Patients noncompliant with DR screening were recruited from Primary Health Care clinics. Questions were adapted from similar published studies. Informed consent was obtained and group discussions were audio recorded, transcribed, and analyzed for themes by three researchers.

RESULTS

Most patients reported financial barriers including the costs of the exam and additional treatments, and transportation to the referral clinic. System related issues were the difficulty of getting appointments and long wait times due to inadequate numbers of ophthalmologists or screening facilities, and physicians failing to recommend screening. Personal concerns related to patients having other priorities, fears about the results, and the negative experiences of family members. Finally, cultural aspects included the stigma of wearing glasses and not doing a test for a condition without symptoms.

CONCLUSIONS

Barriers to completing retinopathy screening are multidimensional with financial, personal, educational, health system, and cultural factors. These should be taken into consideration by policy makers in order to increase the uptake and quality of service.

<p>Self-Reported Awareness of Retinopathy Severity in Diabetic Patients</p>

Background

Diabetic retinopathy (DR) may be asymptomatic in both mild and advanced stages. A patient’s accurate perception of their DR severity may therefore be critical for effective self-management behaviors and understanding the need for timely intervention and follow-up.

Purpose

To evaluate the relationship between self-reported and actual retinopathy severity in diabetic patients.

Methods

This study was a single-center cross-sectional survey. Diabetic patients identified by enterprise data warehouse were sent an online questionnaire where they were asked to self-assess for presence of DR and grade their severity. Actual DR grading was determined via chart review. The primary outcome measures were patient-assessed DR severity and agreement with actual DR severity.

Results

Of 3208 invitations sent, 324 (10%) patients responded and 319 responses were analyzed. The data showed that 39 of 253 (15%) with no DR, 26 of 40 (65%) with mild/moderate DR, and 24 of 26 (92%) with severe DR believed they had DR (p<0.001). Of those with no DR, 214 of 253 (85%) accurately assessed absence of DR. Of those with mild/moderate DR, 25 of 40 (63%) accurately assessed their severity, 14 of 40 (35%) believed they had no DR, and 1 of 40 (3%) believed they had severe DR. In patients with severe DR, 9 of 26 (35%) correctly assessed their severity, 15 of 26 (58%) believed they had mild/moderate DR, and 2 of 26 (8%) believed they had no DR.

Conclusion

Patients with severe DR were the most likely to report presence of DR, but often underestimated their disease severity. Many with mild/moderate DR did not realize they had DR. This consistent underestimation of severity across all a significant barrier to timely follow-up and treatment necessary to prevent future visual impairment.

Awareness of diabetic retinopathy among Saudis with diabetes type 2 in Riyadh city

Objective:

To assess awareness of diabetic retinopathy (DR) for Saudis with diabetes mellitus (DM) type 2 in Riyadh City.

Methods:

A cross-sectional study that used self-administered questionnaires conducted in primary healthcare centers in Riyadh City between October and December 2019.

Results:

There were 267 Saudi participants with diabetes mellitus type 2 visiting primary healthcare clinics. (52.4%) were aged 40 years or above at time of diagnosis with diabetes. (73%) had diabetes for at least 5 years. Most of the participants have a good blood glucose control and they do home measurements. In regard to DR, (64.4%) of participants had no subjective or objective indicators of retinopathy, and (70%) had visited ophthalmology clinics. Majority of the participants were advised about DR or referred to an ophthalmologist by their primary physician, with the percentages being (64.8%) and (59.6%), respectively. Regarding other risk factors of DR, (19.5%) had a family history of DR, (23.2%) of participant are smokers and (41.6%) were hypertensives. Majority of the participants were aware about all the aspects of DR, its consequences, and appropriate management except the laser therapy. In terms of area of living and education respondents, who lived in the center of Riyadh City and the secondary level or less educated participants had the lowest level of education.

Conclusions:

Awareness of DR is acceptable but should not lead this information to reduced awareness and educational programs. Outreach researchers' efforts should cover other directions instead awareness of DR.

Knowledge, attitudes, and practices regarding diabetic retinopathy among primary health care physicians in Al-Hasa, Saudi Arabia

Background

Diabetic retinopathy (DR) has been shown to be the third most observed cause of visual loss in Saudi Arabia. In the Al-Hasa region in particular, the prevalence of DR has been shown to be 30%. Primary health centre (PHC) physicians play a central role in the early detection and prevention of DR. The aim of this study was to evaluate the knowledge, attitudes, and practices regarding DR of PHC physicians in Al-Hasa, Saudi Arabia.

Methods

A cross-sectional descriptive study was conducted at PHCs in Al-Hasa, Saudi Arabia. A self-administered questionnaire was provided to every participant along with a consent form. Out of 71 centres in the region, 63 were included in this study. The questionnaire consisted of three sections and a total of 18 questions. Statistical analysis was carried out using the Statistical Package for the Social Sciences version 21 software program (IBM Corp., Armonk, NY, USA).

Results

One hundred forty-one of 209 physicians completed the questionnaire for a response rate of 67%. The mean of overall knowledge score for all participants was 2.6 ± 1.16 points out of four points. Only 34 (24.1%) of the participants correctly referred their diabetic patients according to the guidelines of the American Academy of Ophthalmology. Additionally, only 52 (36.9%) physicians educated their patients regarding the early detection of diabetic complications.

Conclusion

The present study concluded that there exist gaps in applying the correct guidelines. Physicians’ attitudes toward patient education were overall satisfactory. Further medical symposiums and workshops are warranted to teach physicians about diabetic complications and screening schedules, including DR.

Prevalence, Incidence and Ecological Determinants of Diabetic Retinopathy in Iran: Systematic Review and Meta-analysis

Purpose

To estimate the pooled prevalence and incidence of diabetic retinopathy (DR) in Iran and to investigate their correlations with the Human Development Index (HDI), healthcare access (i.e., density of specialists and sub-specialists), and methodological issues.

Methods

Electronic databases such as PubMed, Embase, Scopus, Web of Science, Google Scholar, and local databases were searched for cohort and cross-sectional studies published prior to January 2018. Prevalence and incidence rates of DR were extracted from January 2000 to December 2017 and random effects models were used to estimate pooled effect sizes. The Joanna Briggs Institute critical appraisal tool was applied for quality assessment of eligible studies.

Results

A total of 55,445 participants across 33 studies were included. The pooled prevalence (95% CI) of DR in diabetic clinics (22 studies), eye clinics (4 studies), and general population (7 studies) was 31.8% (24.5 to 39.2), 57.8% (50.2 to 65.3), and 29.6% (22.6 to 36.5), respectively. It was 7.4% (3.9 to 10.8) for proliferative DR and 7.1% (4.9 to 9.4) for clinically significant macular edema. The heterogeneity of individual estimates of prevalence was highly significant. HDI (P < 0.001), density of specialists (P = 0.004), subspecialists (P < 0.001), and sampling site (P = 0.041) were associated with heterogeneity after the adjustment for type of DR, duration of diabetes, study year, and proportion of diabetics with controlled HbA1C.

Conclusion

Human development and healthcare access were correlated with the prevalence of DR. Data were scarce on the prevalence of DR in less developed provinces. Participant recruitment in eye clinics might overestimate the prevalence of DR.

Identification of population characteristics through implementation of the Comprehensive Diabetic Retinopathy Program

Background

Diabetic retinopathy is the most common cause of blindness in working-age adults. Characteristics of patients with diabetes presenting to a retina subspecialty clinic have not been adequately studied, limiting our ability to risk stratify patients with diabetic retinopathy. Our goal is to describe an innovative program that collects structured, longitudinal data on patients with diabetes in a retina clinic, and identifies population characteristics to define patient risk stratification.

Methods

Demographics, body-mass index, blood pressure, hemoglobin A_1c, smoking history, diabetes type, diabetes duration, kidney disease history, and diagnosis codes were collected on all patients with diabetes at the Kellogg Eye Center retina clinic. A mixed effects negative binomial regression was then performed to assess visit frequency as a function of these variables. Visit frequency was used as a marker for cost of care. A subgroup of patients was surveyed about knowledge of diabetes management goals and barriers to better self-management.

Results

There were 2916 patients in the cohort with 1014 in the subgroup. The cohort was predominantly Caucasian (74.5%), with a mean age of 64 years (range 13–99) and a relatively even distribution of sex (53.2% men). The mean maximum hemoglobin A_1c was 8.0% (range 4.3–15.7%), and 57.1% had a diagnosis of diabetic retinopathy. Patients averaged 3.9 visits (range 1–27) during the 18-month study period. Blood pressure and duration of diabetes were positively associated with visit frequency (p < 0.0001, p < 0.0001, respectively). Of the surveyed patients, 87.6% knew their goal hemoglobin A_1c, while only 45.9% identified the correct blood pressure goal. The most common reported barrier to better self-management was “it’s just not working” (47.1%).

Conclusions

Implementation of this program enables the creation of a longitudinal dataset on patients with diabetes. Resulting data can be used to improve quality of care provided to patients at a retina clinic. The findings suggest considerable healthcare resources are being directed to a small patient population. This enhanced understanding of characteristics of patients with diabetes will improve efforts to preserve vision and utilize health system resources efficiently.

Diabetic patients' awareness of diabetic retinopathy symptoms and complications

Background:

Diabetes is a very common chronic endocrinological disease. A total of 8.8% of the adult population worldwide was diabetics. Diabetic retinopathy is a silent disease, early detection and intervention is essential for its management and prognosis.

Aim:

To assess the diabetic patients’ awareness of diabetic retinopathy symptoms and complications.

Methods:

This is a cross-sectional community-based study which was conducted in Saudi Arabia using a survey from the period between June and September 2018 on all diabetic Saudi participants between 15 and 75 years of age.

Results:

This study involved 385 participants. The average age of the participants was 47.82 ± 14.49. The study only involved patients who were diagnosed with type 1 diabetes mellites (DM) or 2 DM. And 81% of the samples were diagnosed with type 2 DM. A total of 311 participants were aware of the DM effect on the eye. There was a significant difference between gender regarding the effect of DM on the retina in good control patients. On the subject of the source of participants’ knowledge of DM and its complication, there was a notable difference between groups.

Conclusion:

An acceptable level of knowledgewas noted among patients. However, some points of knowledge should be increased.

Awareness of diabetic retinopathy among patients with type 2 diabetes mellitus in primary health care in security forces hospital Riyadh, Saudi Arabia

Background

Diabetes mellitus (DM) is a metabolic disease that is characterized by distortion in the metabolism of carbohydrates, lipids, and proteins and involves hyperglycemia. DM has different types. Several complications are associated with diabetes including diabetic retinopathy (DR). DR can further results in bad outcomes that can be avoided by early diagnosis and management.

Aim

The aim of this paper is to assess the awareness and knowledge level about DR among type 2 DM patients in primary health care in security forces hospital.

Methods

This is a cross-sectional study that was conducted on Saudi patients with type 2 DM who visited primary health care in security forces hospital.

Results

This study included 174 participants, with equal male to female ratio was 1:1, there were 64.9% participants who reported controlled blood glucose level, and 47.1% reported that eye was affected by diabetes. There were 82.8% participants who had awareness about DR; the level of awareness differs significantly with sex (P value = 0.04) and the level of DM control (P value = 0.02).

Conclusion

There was high level of knowledge regarding DR; however, there were few percent of participants who had no awareness and still at risk.

Awareness, knowledge, and practices related to diabetic retinopathy among diabetic patients in primary healthcare centers at Riyadh, Saudi Arabia

Context

Diabetic retinopathy (DR) is a microvascular complication for diabetes mellitus (DM), with around 35% of diabetic patients developing some form of DR.

Aims

This study assessed the awareness toward DR, practice of regular eye examination, and DM control among diabetic patients.

Settings and Design

This was a cross-sectional study among diabetics at two primary healthcare centers in Riyadh, Saudi Arabia, who were selected by convenience sampling.

Methods and Materials

The questionnaire contained sections for demography, knowledge, attitude, and practice toward DR, and compliance to DM treatment. The association of awareness about retinopathy with demographics was compared.

Statistical Analysis Used

The association of awareness about retinopathy and education level with demographics and compliance with treatment were compared using Chi-square test.

Results

In total, 280 diabetic patients were included, 187 (67%) were males, mean age was 58.9 ± 10.1 years, and median duration of diabetes was 10 years. There was good awareness about DR, diabetes was well controlled in 170 (61%) patients, but less than half (45%) had their eyes checked within 1 year. Patients with education level of high school and above had higher awareness than those with no formal education (P < 0.001). Also, those with income level >10,000 SR had higher awareness than those with income ≤5,000 SR (P < 0.05).

Conclusion

There was high awareness among the diabetic patients regarding DR but annual check-up was done in less than half of the patients. Improvement is required for scheduling annual eye examinations for the early detection of DR.

Knowledge, Awareness, and Eye Care-Seeking Behavior in Diabetic Retinopathy: A Cross-Sectional Study in Jeddah, Kingdom of Saudi Arabia

Introduction

Diabetes mellitus (DM) is common metabolic disorder that is characterized by increased circulating blood glucose levels. Long-term, continuous hyperglycemia leads to vasculature-related disorders, including those affecting the eyes, such as retinopathy. The objective of this study was to assess the awareness of diabetic complications, specifically diabetic retinopathy, among diabetic patients attending the Jeddah Eye Hospital.

Methods

This was a cross-sectional study targeting the outpatient clinics of Jeddah Eye Hospital for a period of 2 months. A total of 380 participants were randomly selected based on sample size calculations. A closed-ended questionnaire, generated after an extensive literature review, was distributed among the selected individuals. The questions focused on the participants’ clinical status of DM, socio-demographic characteristics, awareness of eye complications secondary to DM, eye screening, and eye care-seeking behavior.

Results

The mean age of the patients was 58.3 (standard deviation 10.9) years, and 52.4% of patients were female. The majority (89.7%) of participants had type II DM (T2DM). The level of awareness was satisfactory (92.4%); however, only 10.5% of participants knew the recommended frequency for eye check-ups. The level of awareness of related complications was directly influenced by education level, source of patient information, place of residence, and frequency of follow-up visits.

Conclusion

The results of this study indicate that although the awareness of diabetes-related eye complications was satisfactory in the patient population, eye care-seeking behavior and frequency of eye check-ups were not optimal. Efforts are needed to promote eye care-seeking behavior in this patient group.

Awareness of diabetic retinopathy among people with diabetes in Jeddah, Saudi Arabia

BACKGROUND

Diabetic retinopathy (DR) is the most common microvascular complication of diabetes mellitus (DM) and the foremost cause of blindness. This study aimed to assess the level of awareness of DR and its related risk factors among patients with DM in Jeddah, Saudi Arabia.

METHODS

A cross-sectional study was conducted among patients with DM attending primary health care centers at the Ministry of Health in Jeddah. A structured, pretested, self-administered questionnaire was used to collect information on the sociodemographic and DM- and DR-related characteristics of the patients.

RESULTS

A total of 377 patients were enrolled. About 82.6% of the patients were aware that DM can affect their eyes, and they listed physicians, ophthalmologists, television, and family members as common sources of information on the topic. About 36% of the patients reported that their doctors had not advised them about it. More than half responded that they did not feel their vision to be affected by DM. More than 58% had never been diagnosed with DR. About 35% did not go to their eye checkups, even though around 59% thought that DR could lead to blindness. Of the 64% of patients whose DM was well controlled, 11% and 25% listed surgery and laser treatment, respectively, as available treatment options for DR. The following factors were found to be significant in relation to the subjects' awareness that DM can affect their eyes: the patients' perception of their doctors' advice about DR; the experience of having their vision affected by DM; the knowledge that DR may lead to blindness; the practice of going to eye checkups.

CONCLUSIONS

Despite having good awareness about DM and its effects on eyes, the patients exhibited a relative lack of awareness about DR. Considering the association of DR with DM, its increasing magnitude is a potential burden on the community and health systems.

Assessment of visual morbidity amongst diabetic retinopathy at tertiary eye care center, Nepal: a cross-sectional descriptive study

BACKGROUND

Diabetic retinopathy (DR) is one of the leading causes of preventable blindness in low and middle income countries. In Nepal, there are less studies regarding DR and they too are limited around Kathmandu valley. This study was done to assess visual morbidity in patients with DR at a peripheral tertiary eye care center of Nepal.

METHODS

This was a prospective, hospital based, cross-sectional study in which all consecutive cases of DR were evaluated. DR was classified according to Early Treatment Diabetic Retinopathy Study Research Group - report no. 10 Table A5-1 (Modified Airlie House Classification). Data entry and analysis was done in an SPSS unit version 20. Wherever applicable, variables were set as 100 eyes.

RESULTS

Total number of patients included in this study was 50. Commonest age group was 50-69 yrs. (43/77 yrs.; min/max) comprising 80% of the total population (n = 50) and the predominant population was male (76%). Non proliferative diabetic retinopathy (NPDR) was found in 69%, proliferative diabetic retinopathy (PDR) in 31% and advanced diabetic eye disease (ADED) in 3% (n = 100).

CONCLUSIONS

All the stages of DR were present at significant proportions in this study, noteworthy was the percentage of PDR. This study shows an urgency to gather a national data on DR, raise awareness among diabetics and train effective man power at a local level to diagnose DR at an early stage.

Predictive factors of visual outcome of Malaysian cataract patients: a retrospective study

AIM

To explore the associations between various characteristics of Malaysian cataract patients and their management, and their post-operative visual outcomes, to inform relevant bodies to reduce cataract-related blindness.

METHODS

We conducted a descriptive secondary data analysis of cataract surgery patients in Melaka Hospital, from 2007 to 2014 using the National Eye Database (NED). Patient-related factors (demographic features, systemic and ocular comorbidities) and management-related factors (surgical duration, type of surgery, type of lens) were analysed for their association with visual outcome (acuity).

RESULTS

Most patients were Malays (48.23%) and Chinese (38.55%) aged 60-79y (range 0-100y). Hypertension (58.61%) and diabetes (44.89%) were major systemic comorbidities. Glaucoma (6.71%) and diabetic retinopathy (10.12%) were the main ocular comorbidities. Other comorbidities were age-related macular degeneration, pterygium, corneal opacities, macula diseases, vitreous haemorrhage, retinal detachment and pseudoexfoliation (0.70%-1.60%). Preoperatively 7150 (55.03%) eyes presented with poor vision. Uncomplicated phacoemulsification performed quickly with foldable lenses gave good results.

CONCLUSION

Primary care physicians should initiate early detection to prevent late presentation of cataracts causing poor vision and should discuss the risks and benefits of cataract surgery while emphasizing the role of pre-existing comorbidities which may affect the visual outcomes. For good results, phacoemulsification should be done within 30min, without complications, using foldable posterior chamber intraocular lens.

Awareness and practices regarding eye diseases among patients with diabetes: a cross sectional analysis of the CoDiab-VD cohort

BACKGROUND

The increasing prevalence of diabetes is leading to a rise of eye diseases, augmenting the risk of sight-threatening complications. The aim of this study was to evaluate prevalence, awareness and practices regarding eye diseases among patients with diabetes in the canton of Vaud, Switzerland.

METHODS

A cohort of 323 patients with diabetes completed a self-administered questionnaire assessing prevalence, awareness and practices regarding eye diseases, besides health status and quality of care measures. Descriptive analyses followed by exploratory subgroup analyses and linear regressions were performed to investigate factors associated with awareness and practices.

RESULTS

While diabetic retinopathy was reported by 40.9% of patients with type 1 diabetes and 9.8% of patients with type 2 diabetes, 35.8% and 12.6% of all participants reported cataract and glaucoma, respectively. Awareness that diabetes could damage the eyes was reported by almost all participants; the majority was also aware of the importance of glycemic control and regular eye examination in preventing eye diseases. In contrast, only 70.5% of participants underwent an eye examination by an ophthalmologist during the past year. Eye examination was associated with better patients' awareness. Barriers mentioned by patients revealed a lack of knowledge about screening guidelines, in particular regarding the preventive nature of eye examinations.

CONCLUSIONS

Despite high levels of awareness regarding diabetic eye diseases, a significant proportion of patients with diabetes did not report annual eye examination. Both healthcare strategic efforts targeting the promotion of regular eye examination and initiatives aiming at improving knowledge of screening guidelines should be encouraged.

Awareness of diabetic retinopathy among patients with type 2 diabetes mellitus in Jordan

BACKGROUND

Increasing the level of awareness of diabetic retinopathy among individuals with type 2 diabetes mellitus is considered an important factor for early diagnosis and management of diabetic retinopathy. The aim of this study was to evaluate awareness of diabetic retinopathy among a sample of type 2 diabetes mellitus patients in Jordan.

PATIENTS AND METHODS

The study period was from August to December 2015. The sample was selected randomly from patients with type 2 diabetes mellitus from the general population in three main cities of Jordan (Amman, Irbid, and Zarqa). A questionnaire was distributed to 237 participants with diabetes to assess their awareness and knowledge of diabetes and diabetic retinopathy. The questionnaire included questions to assess awareness about diabetic retinopathy, sources of knowledge about the disease, and patients' knowledge and compliance with available treatments and routine eye examinations. Patients were also questioned about the barriers that may interfere with early eye examination.

RESULTS

A total of 237 participants (107 [45.1%] females and 130 [54.9%] males) with type 2 diabetes were interviewed. Mean age±SD for the study population was 54.51±10.28 years. Of the study population, 88.2% were aware that diabetes can affect the eyes and 81% reported that diabetic retinopathy can lead to blindness. Higher level of patients' awareness of diabetic retinopathy was related to higher level of formal education (p<0.05). The main source of information about diabetic retinopathy as reported by 47.3% patients was general practitioners. Patients' compliance with diabetes management was relatively high; however, their compliance with routine retinal assessment was poor, with only a total of 29.5% of participants having had an eye examination in the previous year.

CONCLUSION

Awareness of the nature and consequences of diabetic retinopathy among patients with diabetes in Jordan is relatively high. However, patients' motivation to undergo retinal assessment was poor in the sample, thus hindering early diagnosis and management.

Diabetic care initiatives to prevent blindness from diabetic retinopathy in India

It is estimated that 65 million (17%) of 382 million persons with diabetes mellitus (DM) globally reside in India. While globally 35% persons with DM have diabetic retinopathy (DR), this proportion is reportedly lower in India, other countries in South Asia and China. We reviewed published data from 2008 onwards from PubMed, which ascertained DR in population-based representative samples. We also reviewed the risk factors for DR, on awareness regarding eye complications and on accessing an eye examination. Thirteen research studies have reported on the prevalence of DR among persons with DM; this prevalence was lower than the global level in China, India, and Nepal. Eleven studies reported DR risk factors association. The duration of diabetes and level of glycemic control were universally acknowledged DR risk factors. We identified 7 studies in the Asia region that researched the level of awareness about diabetes eye complications and the practice of accessing an eye examination. Excepting 1 study in China, others reported a significant proportion being aware that diabetes leads to eye complications. But the awareness was not translated into a positive practice-most studies reported only 20-50% of the persons with diabetes actually having had their eyes examined. The present review highlights the observation that the risk factors for DR need an integrated diabetic care pathway where the eye care team has to work in close collaboration and partnership with a diabetic care team has to reduce the risk of blindness from DR.

Perception of care and barriers to treatment in individuals with diabetic retinopathy in India: 11-city 9-state study

BACKGROUND

Diabetic retinopathy is a leading cause of visual impairment. Low awareness about the disease and inequitable distribution of care are major challenges in India.

OBJECTIVES

Assess perception of care and challenges faced in availing care among diabetics.

MATERIALS AND METHODS

The cross-sectional, hospital based survey was conducted in eleven cities. In each city, public and private providers of eye-care were identified. Both multispecialty and standalone facilities were included. Specially designed semi-open ended questionnaires were administered to the clients.

RESULTS

376 diabetics were interviewed in the eye clinics, of whom 62.8% (236) were selected from facilities in cities with a population of 7 million or more. The mean duration of known diabetes was 11.1 (±7.7) years. Half the respondents understood the meaning of adequate glycemic control and 45% reported that they had visual loss when they first presented to an eye facility. Facilities in smaller cities and those with higher educational status were found to be statistically significant predictors of self-reported good/adequate control of diabetes. The correct awareness of glycemic control was significantly high among attending privately-funded facilities and higher educational status. Self-monitoring of glycemic status at home was significantly associated with respondents from larger cities, privately-funded facilities, those who were better educated and reported longer duration of diabetes. Duration of diabetes (41%), poor glycemic control (39.4%) and age (20.7%) were identified as the leading causes of DR. The commonest challenges faced were lifestyle/behavior related.

CONCLUSIONS

The findings have significant implications for the organization of diabetes services in India.
