The Effects of Cataract Surgery on Children's Vision: A Systematic Review. JOURNAL OF PHARMACY AND BIOALLIED SCIENCES 2024; 16:S67-S71. [PMID: 38595431 PMCID: PMC11000933 DOI: 10.4103/jpbs.jpbs_995_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Revised: 10/10/2023] [Accepted: 10/22/2023] [Indexed: 04/11/2024] Open
Abstract
Background Five-fifths of all incidents of blindness in Saudi Arabia may be attributed to cataracts. Cataracts are the second major cause of blindness, responsible for 35.5% of cases. Therefore, the purpose of the research was to measure the visual acuity improvement after cataract surgery in children. Materials and Methods This systematic review followed PRISMA guidelines for reporting systematic reviews. All procedures followed the recommendations of the Cochrane handbook. Studies of varying study designs, both published and unpublished, are included. Retrospective studies with outcomes of pediatric cataract surgery were identified from various databases. Result After an initial screening, 108 out of 167 items were deemed unsuitable for publication. There were 59 full-text papers assessed for inclusion, and only seven matched the criteria. All the articles included were of a very high standard. Both the duration of therapy and the target population varied widely between the studies. Conclusion The results indicated that the majority of childhood cataracts are hereditary. Primary posterior capsulectomy and anterior vitrectomy combined with cataract extraction and intra-ocular lens implantation is the treatment of choice for pediatric cataracts. It is recommended that surgery be performed in a properly equipped facility staffed by trained, cooperative personnel and that different procedures be used to enhance post-operative follow-up.

Abstract
BACKGROUND Child eye health is a serious public health issue in Ethiopia, where children under the age of 15 account for over half of the population. Our aim was to review Ethiopian health policy and practice to reveal approaches and commitment to promotion and delivery of child eye health services. METHODS We conducted a mixed-methods situational analysis employing documentary analysis and key informant interview methods. Government publications touching on any element of child eye health were included. Key informants were eligible if they were leaders, authorities, researchers or clinicians involved in child health. Data was combined and analysed by narrative synthesis, using an adaptation of the Eye Care Situation Analysis Tool as a framework. FINDINGS Eleven documents developed by the Ministries of Health and Education were included and interviews with 14 key informants were conducted. A focus on child eye health was lacking in key health policy documents, demonstrated by limited allocation of funds, a shortage of human resources, and a subpar referral system across all levels of child eye care. CONCLUSION The study identified several gaps and limitations in child eye health in Ethiopia. There is a need for health policies that strengthen ownership, finance and partnerships for improved coordination, and collaboration with line ministries and other stakeholders to improve child eye health services in Ethiopia.

Abstract
BACKGROUND The majority of childhood blindness causes in low-income countries are treatable or avoidable. Parents or guardians are responsible for making decisions regarding a child's eye care. Understanding parents' awareness and perception of eye problems in crucial in helping to know parents' eye care-seeking behavior. OBJECTIVE To determine parental knowledge, attitudes and practice regarding child eye health. METHODS Seven focus groups were carried out in Northwest Ethiopia on knowledge, attitude and practice of parents towards child eye health. Their responses were tape-recorded and later transcribed. A thematic phenomenological approach was used for the analysis. RESULT Seventy-one parents participated in the focus groups. Participants were aware of common eye problems like trachoma, trauma, and glaucoma. However, they were unaware of the causes and etiologies of childhood blindness. Participants perceived that eye problems could be treated with hygiene and food, and often held misconceptions about the cause of strabismus and utilization of wearing spectacles. CONCLUSION The study revealed that parents are often unaware of the causes and etiologies of common childhood eye diseases, which has downstream effects on health-seeking behavior. Health promotion efforts, potentially through mass and social media, could be helpful to raise awareness, coupled with training of health professionals at primary and secondary health facility levels.

[PMID: 37749375 DOI: 10.1038/s41433-023-02755-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Revised: 09/08/2023] [Accepted: 09/13/2023] [Indexed: 09/27/2023] Open
Abstract
OBJECTIVE To describe the practice patterns for the management of paediatric cataracts among ophthalmologists practising in Nigeria. METHODS A cross-sectional study of fully trained Nigerian ophthalmologists who perform cataract surgery in children aged 16 years and below. An online questionnaire was distributed via e-mail and social media platforms to respondents. Data on socio-demographic characteristics, type, location and years of practice, status and preferred approach to management of childhood cataracts were obtained and analysed. RESULTS A total of 41 ophthalmologists responded that they perform paediatric cataract surgery. Of these, 25 (61.0%) were paediatric ophthalmologists while 7 (17.0%) were general ophthalmologists. Most respondents (92.7%) practise in urban settings and 30 (73.2%) work in tertiary hospitals. Most respondents (90.2%) routinely insert intraocular lenses (IOLs) in children aged 2 years and above while 32 (78.0%) routinely under-correct the IOL power. Thirty-four (82.9%) have an anterior vitrectomy machine, 31 (75.6%) routinely perform posterior capsulotomy and anterior vitrectomy, and 17 (58.5%) routinely perform same-day sequential bilateral cataract surgery. Twenty-six (63.4%) respondents routinely give near correction in aphakic children, while 24 (58.5%) respondents routinely give bifocals in pseudophakic children. Compared to other sub-specialists, paediatric ophthalmologists were 24 times more likely to routinely under-correct IOL power (p = 0.001) and 4 times more likely to routinely correct near vision in aphakic children (0.036) as well as prescribe bifocals for pseudophakic children respectively (0.029). CONCLUSION The practice of paediatric cataract surgery in Nigeria is mainly in line with expected standards, but there is a need for the development of detailed practice guidelines.

Abstract
CONTEXT This study aimed to know the clinical and demographic profile of pediatric cataracts in Oman. AIMS The aim of this study was to describe the demographic and clinical profile of pediatric cataracts in a tertiary care hospital, Oman. SETTINGS AND DESIGN This was a hospital-based, retrospective observational study. SUBJECTS AND METHODS A retrospective cross-sectional study of all Omani children presented to ophthalmology outpatient at a tertiary hospital, between January 2012 and December 2016. All patients aged <18 years presented with lens opacity were included in the study. Traumatic cataract cases were excluded from the study. STATISTICAL ANALYSIS USED SPSS version 22.0 International Business Machines, (Armonk, New York, Unites States of America, dated 8/13/13) used for statistical analysis. RESULTS Among 379 eyes of 239 patients, 58.6% (140 patients) had bilateral cataracts. Male-to-female ratio was 1.38:1. We arrived at prevalence of 4.32 with 95% confidence interval (3.85, 4.77) of congenital cataract cases/10,000 Omani Children. Most patients (54%) were from either Muscat (28.9%) or A'Sharqiyah (25.1%). The median age of cataracts first noticed by parents was 3 months and the median age of presentation to the eye care unit was 15 months. Patients with positive family history significantly (P = 0.007) presented with bilateral cataracts (75%). About 22.2% of the patients had associated systemic diseases. Among those with systemic association, 77.4% of cases had bilateral cataracts. About 35.4% of eyes had another ocular association. The most common ocular association was squint (11.1%). The most common cataract morphologies at presentation were 20.1% presenting with total lens opacities and 19.8% with posterior subcapsular/posterior lenticonus. CONCLUSIONS A higher demographic distribution of pediatric cataracts was found in Muscat governorate. There was a significant median delay in presentation to the pediatric ophthalmology clinic by 12 months since lens opacity was first noticed by parents.

Abstract
Objective To describe a cohort of paediatric patients who underwent unilateral or bilateral lens extractions at Ghent University hospital using the Dutch Ophthalmic Research Center (D.O.R.C.) ultra-short 27G vitrectomy system. Methods Retrospective analysis of the medical and surgical records of all children that underwent lens extraction between September 2016 and September 2020 using the D.O.R.C. ultra-short 27G vitrectomy system. Results Seventy-two eyes of 52 patients were included. The most important aetiologies in this study were of secondary (25.5%), developmental (13.7%), or genetic (13.7%) nature. No definitive cause could be established in more than a quarter of cases (27.5%) despite extensive work-up, them being deemed idiopathic. The remainder of cases (19.6%) was not assigned a final aetiologic designation at the time of the study due to contradicting or missing diagnostic data. This study could not identify any cataract cases related to infection or trauma. Surgical complications rate was 61.1% of which posterior capsule opacification was the most frequent with a rate of 25%. A significant short-term postoperative best-corrected visual acuity gain (≤ -0.2 LogMAR) was observed in 60.5% of eyes for which usable acuity data were available (n = 38). Conclusion Many different instruments and techniques have been described and used in the context of paediatric lens extractions, each with its advantages and disadvantages. This study illustrates that an ultra-short 27G vitrectomy system can be used to perform paediatric lens extractions with good surgical outcomes. Further studies and comparative trials are needed to ascertain this further.

Abstract
PURPOSE Evaluation for systemic diagnosis is an important part of pediatric cataract management. While there are reports on associated systemic and ocular associations in children with infantile cataracts, reports specifying associations in large cohorts of children undergoing cataract surgery are lacking. METHODS Retrospective chart review of consecutive patients undergoing cataract surgery at a pediatric tertiary referral center during 30-year period was performed. Associated systemic and ocular associations were recorded. The etiologies were analyzed depending on laterality, age, and gender. RESULTS Seven-hundred twenty-seven patients (1135 eyes) were included for analysis: 408 (56%) with bilateral and 319 (44%) with unilateral cataract. An identifiable cause for cataract was identified in 66% (270/408) bilateral and 55% (176/319) unilateral cataract patients. Hereditary cataract accounted for 22% of bilateral cataracts. An underlying syndrome or genetic diagnosis was found in 24% bilateral (97/408, 86 genetic/syndromic, 11 metabolic) but only in 2% of unilateral cases (5/319). Cataracts were the result of treatment for cancer, or other systemic conditions requiring steroids, in 60/408 bilateral (15%) and 15/319 (5%) unilateral cataract patients. In contrast, unilateral cataracts had higher ocular associations (49%, 156/319) than bilateral cataracts (6%, 23/408) primarily ocular trauma (20%, 64/319) and persistent fetal vasculature (20%, 62/319). CONCLUSION Clinicians should be aware of potential systemic and ocular associations among children with visually significant cataracts. Those with no family history of juvenile cataract should be evaluated for systemic associations, and referral to genetics may be warranted in select cases.

Abstract
Purpose To analyze intraoperative difficulties and visual and surgical outcomes following pediatric cataract surgery. Methods This five-year retrospective study (2014-2019) included 138 eyes (85 children) with cataract aged between 12 months and 18 years (either sex). All children had undergone best-corrected visual acuity (BCVA), anterior and posterior segment evaluation, intraocular lens (IOL) power calculation, superior manual-small-incision cataract surgery (MSICS) with or without posterior capsulotomy/anterior vitrectomy and IOL implantation under general or local anesthesia, visual rehabilitation, and had been followed up for a minimum period of 12 months. Results The mean age was 111.27 ± 4.84 months. Preoperative BCVA distance: 113 (81.88%)eyes had BCVA < 6/60; near BCVA: 114 (82.6%) eyes had ≤N36. At last postoperative follow-up (mean: 20.98 ± 13.08 months): distant BCVA- ≥6/60 had been recorded in 120 (86.96%) eyes; near BCVA- >N36 in 123 (89.13%) eyes. Improvement in BCVA was statistically significant. Intraoperative scleral tunnel difficulties were seen in three eyes (thin flap in two, and buttonhole in one eye); in the majority of the eyes 113 (81.88%), IOL was placed in the bag. Twenty eyes had early postoperative inflammation. At last follow-up: posterior capsular opacity was recorded in six eyes, IOL decenteration in two eyes, secondary glaucoma in six eyes, and severe amblyopia in 36 (26.09%) eyes. The mean myopic shift was - 1.11 ± 0.89 D and was statistically significant. Conclusion Superior MSICS as a treatment for pediatric cataract has minimal intraoperative complications and satisfactory visual and surgical outcomes.

Abstract
PURPOSE The final refraction after intraocular lens (IOL) implantation remains a challenge in the management of paediatric cataracts. No consensual guidelines exist for the choice of IOL power. The aim of this study was to validate a method of IOL power calculation by evaluating the final refractive error in all patients with IOL implantation operated at our institution. METHODS We retrospectively studied all children under 7 years of age who underwent cataract surgery with IOL implantation at our institution between 2010 and 2015. Intraocular lens (IOL) power was calculated as follows: After B-scan determination of the emmetropic IOL power, a reduction of 40%, 35%, 30%, 25%, 20%, 15%, 10% and 5% was applied to children 0-3, 3-6, 6-12, 12-18, 18-24, 24-30, 30-36, 36-48 months, respectively. The following data were collected: follow-up, age at surgery, uni- or bilaterality, implanted IOL power and final refraction. RESULTS During this period, 81 children (125 eyes) met the inclusion criteria with a median follow-up of 60 months (36-97). The median age at surgery was 6.61 months (0.76-48). We included 52 children with bilateral cataract (96 eyes) and 29 children with unilateral cataract (29 eyes). The mean implanted IOL power was 23.3 ± 4.6 diopters (D). The mean spherical equivalent at last follow-up was 0.07 ± 3.5 D. CONCLUSION Our undercorrection formula for IOL implantation after congenital cataract surgery leads to long-term refractive results globally close to emmetropia.

Abstract
ObjectivesTo evaluate the eye-related quality of life (ER-QOL), functional vision, and their determinants in children following congenital and developmental cataract surgery, as the impact on their families, using the Pediatric Eye Questionnaire (PedEyeQ).Materials and MethodsThis was a retrospective cross-sectional study involving 107 children (aged 0–11 years) with congenital and developmental cataracts who had undergone surgery, as well as 59 visually healthy controls (aged 0–11 years). One parent for each child completed either the Proxy 0–4 PedEyeQ, the Proxy 5–11 PedEyeQ, or the Parent PedEyeQ, depending on their child's age. Mann-Whitney U and Kruskal-Wallis tests were then conducted to compare the differences between groups and to analyze their determinants.ResultsPedEyeQ scores were found to be lower in postoperative children with congenital and developmental cataracts compared with the control group across all study domains. The PedEyeQ Proxy 0 to 4 years' greatest mean difference was 27 points worse in the Functional Vision domain (95% CI −34 to −19; p < 0.001). We also found that the occurrence of nystagmus (p < 0.005) and strabismus (p < 0.005) were the major factors affecting participants' functional vision. The PedEyeQ Proxy 5 to 11 years' greatest mean difference was 23 points worse in this same domain (95% CI −30 to −15; p < 0.001), with nystagmus (p < 0.05) being the main determinant herein. Parent PedEyeQ 0 to 4 years' greatest difference was 46 points worse on the Worry about their Child's Eye Condition domain (95% CI −57 to −36; p < 0.001). Similarly, parents of children with ophthalmologic abnormalities, including nystagmus (p < 0.001) and strabismus (p < 0.05), were significantly more worried about their children's eye condition. Parent PedEyeQ 5 to 11 years' greatest difference was also found to be 30 points worse on the Worry about their Child's Eye Condition domain (95% CI −43 to −17; p < 0.005).ConclusionsChildren who have undergone congenital and developmental cataract surgery experience a lower quality of life and reduced functional vision. Their families are also significantly and adversely affected herein. Thus, more attention is needed on these groups, with more focused measures being administered to both children and their families.

Boonstra N, Haugen OH. Bag-in-the-lens intraocular lens in paediatric cataract surgery: intraoperative and postoperative outcomes. Acta Ophthalmol 2022; 100:e135-e141. [PMID: 33949791 DOI: 10.1111/aos.14878] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 03/27/2021] [Accepted: 04/04/2021] [Indexed: 01/22/2023]
Abstract
PURPOSE To report intra- and postoperative surgical outcome using the bag-in-the-lens (BIL) technique in paediatric cataract surgery. METHODS In a retrospective case series, we studied the outcomes of children aged <12 years operated for cataract with the bag-in-the-lens intraocular lens (IOL), with a minimum of 6 months of follow-up. RESULTS Since 2013, 50 eyes in 30 patients <12 years (20 bilateral and 10 unilateral) have been operated at our department with the BIL technique, with a median follow-up time of 33.5 months (range 6-77). Median age at surgery was 49.5 months (4-139). In one case, the IOL luxated through the capsulorhexes to the vitreous, but could be secured and repositioned as planned without further difficulties. Anterior vitrectomy was necessary in one case due to prolapse of vitreous to the anterior chamber during surgery. No other intraoperative complications occurred. Visual axis opacification (VAO) developed in four eyes (8%). So far, only one of these has needed a reoperation with clearing of the secondary cataract. A complete absence of VAO was thus seen throughout the study period in 92%. In two eyes, postoperative iris capture occurred. In both cases, surgical repositioning of the iris was needed. No eyes developed secondary glaucoma during the study period. CONCLUSION The BIL technique seems to be a safe surgical procedure in paediatric cataract, with significantly less complications and need for additional surgery compared with the conventional lens-in-the-bag technique.

BMC Ophthalmol 2021; 21:441. [PMID: 34949177 PMCID: PMC8697431 DOI: 10.1186/s12886-021-02184-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Accepted: 11/21/2021] [Indexed: 11/10/2022] Open
Abstract
Background To identify the capsule enlargement index after femtosecond laser-assisted anterior capsulorhexis in 2–6-year-old children who underwent congenital cataract surgery. Methods In this prospective case series study, femtosecond laser-assisted anterior capsulorhexis was performed in patients with congenital cataract, aged 2–6 years. The actual achieved capsulorhexis diameters were measured with Digimizer version 4.2.6. Correlation coefficient (r) and multiple linear regression analysis were used to evaluate the variables that could potentially influence anterior capsulorhexis enlargement index (E). Results This prospective study enrolled 28 eyes of 22 patients with congenital cataract. The mean age of the patients at surgery was 4.67 years ±1.54 (standard deviation [SD]). “E” of the 28 cases was 1.211 ± 0.039 (SD). Correlation analysis showed that “E” correlated significantly with the anterior chamber depth (ACD) (r = − 0.469, p = 0.021) and axial length (AL) (r = 0.452, p = 0.027). The following formula was developed by using multivariable linear regression analysis: Predicted E = 1.177–0.052 × ACD + 0.009 × AL, R2 = 0.346 (F = 4.396, p = 0.046). Conclusions The anterior capsulorhexis enlargement index and its calculation formula could help to set up an accurate programmed capsulorhexis diameter for femtosecond laser-assisted congenital cataract surgery in children aged 2–6 years. Thus, an appropriate actual capsulorhexis diameter could be achieved.

Abstract
The aim of this study was to analyze the use of the diagnostic B-scan ultrasound. Should it be made accessible to all surgical centers in Sub-Saharan Africa in order to (i) avoid unnecessary cataract surgery and (ii) evaluate extraocular pathology? This study was conducted in Kinshasa from 2006 to 2019. Three hundred and twenty-three patients were included and separated into two groups. Group 1 included 262 patients with dense cataract. Group 2 consisted of 61 patients with pathologies of the ocular adnexa, and all were examined with a B-scan ultrasound. In group 1, there were 437 systematically screened eyes. Three hundred and ninety-eight eyes (91.08%) showed no abnormalities, 13 (2.97%) retinal detachments were identified, and 15 (3.43%) demonstrated a detached posterior hyaloid membrane. In the second group, 61 patients were examined (group 2). In 20 of them, surgery was performed for biopsy, tumor excision, mucoceles drainage, and palliative treatment. The need for routine B-scan examinations in dense cataract patients seems to be limited and can most likely be replaced by a thorough application of locally available examination techniques. B-scan application is recommended to manage orbital patients in the most cost-effective way.

Abstract
INTRODUCTION The leading cause of childhood blindness globally is paediatric cataract. Bilateral cataract surgery can help to improve visual performance and to diminish the burden of childhood blindness. OBJECTIVE To report in a retrospective observational cohort study the long-term outcomes of 298 children who had bilateral cataract surgery with IOL implantation from 2001-2016 in Kinshasa. METHODS A standardized surgical treatment of paediatric cataract was practiced on 298 children. Patient's follow-up, complications, and visual outcomes were recorded and analysed. RESULTS The mean age was 5.7 ± 4.3 years and males were predominant (64.9%). Most of children were living mainly in urban poorest areas (96.3%). Strabismus, nystagmus and microcornea were encountered in 20.1%, 25.1% and 8.7% of children, respectively. Using WHO criteria most of patients were classified as blind preoperatively and 81.9% of them had improved visual outcomes after surgery. Main reasons for reduced vision during follow-up were secondary cataract (5.7%), IOL decentration (1.2%), retinal detachment (1.2%), and secondary glaucoma (1.5%). CONCLUSION In spite of the post conflict challenges, elimination of cataract blindness in children remains a priority. Children present at a late age for surgery and long term follow-up is poor. There is need for program strengthening in these areas.

Abstract
PURPOSE To evaluate the precision of bag-in-the-lens intraocular lens (BIL IOL) power calculation in different age groups of pediatric cataract patients. SETTINGS Department of Ophthalmology, Justus-Liebig-University Giessen, University Hospital Giessen and Marburg GmbH, Campus Giessen, Giessen, Germany. DESIGN Retrospective nonrandomized consecutive case series. METHODS Pediatric patients diagnosed with cataract and operated with BIL IOL implantation were divided into 4 age groups: Group 1 (0 to 3 months), Group 2 (>3 months, <12 months), Group 3 (12 to 36 months), and Group 4 (>36 months to 17 years). BIL IOL power was calculated with the SRK/T formula. The prediction error (PE) was defined as the absolute difference between the preoperative selected target and postoperative achieved refraction. The impact of age at the time of surgery, axial length (AL), keratometry, and corneal astigmatism on PE was analyzed. RESULTS The study comprised 87 eyes of 56 pediatric patients. The mean and median PEs for the entire group were 1.79 diopters (D) and 1.23 D, respectively. The mean PE in each age group was: 3.43 D in Group 1, 2.14 D in Group 2, 1.60 D in Group 3, and 1.33 D in Group 4. The mean PE in eyes with ALs shorter than 20 mm was 2.67 D, and 1.44 D in eyes with an AL of 20 mm or longer. The mean PE in eyes with corneal radii less than 7.3 mm was 2.45 D, and 1.66 D in eyes with corneal radii of 7.3 mm or more. In the age and AL subgroups, the PE differences were statistically significant (P < .05). CONCLUSIONS The PE was larger in the youngest study group, and it decreased gradually with age and in eyes with ALs shorter than 20 mm. The PE has to be considered during BIL IOL power calculation in children.

Abstract
Background Recent reports have suggested a significant change in the causes of blindness in children in low-income countries cataract becoming the leading cause. We aimed to investigate the presentations and surgical outcomes in children with cataract operated at different ages in Tanzania. Methods We conducted a prospective study of 228 children aged ≤192 months at three tertiary centres, 177 with bilateral cataracts and prospectively followed them for 1-year postsurgery. We collected demographic, surgical, preoperative and postoperative clinical characteristics using the standard childhood cataract surgical assessment questionnaire. Families were encouraged to return for follow-up by phone with travel reimbursement where necessary. Results Preoperatively, 76% bilateral children were blind in the better eye. 86% of children were followed up at 1 year and 54% bilateral children achieved visual acuity of 0.48 logMAR or better in the better eye and 5% were blind. 33% of unilateral children achieved visual acuity of 0.48 logMAR or better and 17% were blind. Preoperative blindness (adjusted OR (AOR) 14.65; 95% CI 2.21 to 97.20), preoperative nystagmus/strabismus (AOR 9.22; 95% CI 2.66 to 31.97) and aphakia (AOR, 5.32; 95% CI 1.05 to 26.97) predicted poor visual outcome in bilateral cases. 9% of 342 refracted eyes had initial postoperative cylinder of 1.5 D or more, as did a similar proportion (11%) of 315 eyes refracted 1 year after surgery. Acute fibrinous uveitis occurred in 41 (12%) eyes. Conclusion Three-quarters of children were blind preoperatively whereas over half had good vision 1-year postoperatively. Preoperative blindness, nystagmus/strabismus and aphakia predicted poor visual outcome, suggesting that cataract density determines density of amblyopia.

Abstract
PURPOSE To report the characteristics and longitudinal visual outcomes of traumatic cataracts and retinal detachments in children with self-inflicted injury. METHODS A retrospective case series of pediatric patients at a tertiary care center who sustained ocular trauma due to self-inflicted injury between 2000 and 2014. RESULTS A total of 11 children, all with an intellectual disability and a mean age of 10 ± 4.8 years (range, 2.8-16.2), were identified with traumatic cataract secondary to ocular self-inflicted injury over the study period. Five eyes had a concurrent unilateral retinal detachment. Over the course of follow-up, one additional eye developed a cataract and five eyes developed a retinal detachment. Patients underwent an average of 2.5 ± 2.3 procedures and 17.1 ± 10.7 eye examinations over 11.7 ± 4.2 years of follow-up; 36% required general anesthesia for examination. Visual acuity was improved or preserved in 77% of the eyes that underwent surgical interventions, but was worse in the remaining cases due to development of traumatic retinal detachment. The use of protective helmets, eye shields, and immobilizing orthoses were essential in management of active self-inflicted injury. CONCLUSION Traumatic cataracts and retinal detachments due to self-inflicted injury may cause severe visual loss. Visual prognosis although poor in children with severe intellectual disabilities may be optimized with risk awareness for early detection and customized interventions.

Abstract
PURPOSE To report the rate and management of intra- and early postoperative complications of bag-in-the-lens intraocular lens (IOL) implantation technique for cataract treatment in paediatric patients of different age groups. SETTINGS Department of Ophthalmology, Justus-Liebig-University Giessen, University Hospital Giessen and Marburg GmbH, Campus Giessen, Giessen, Germany. DESIGN Retrospective non-randomized consecutive case series. METHODS Ninety eyes of 60 paediatric cataract patients were enrolled to this retrospective non-randomized observational consecutive case series single-centre study. All patients underwent cataract surgery with bag-in-the-lens IOL implantation between January 2008 and December 2018, performed by two experienced surgeons. The entire cohort was divided into four age groups: first - 0-<3 months, second - 3-<12 months, third - 12-<36 and fourth - >36 months-17 years of age. The intra- and postoperative complications were based on the clinical records. The description of management of complications related specifically to bag-in-the-lens IOL technique was based on the 39 consecutive cases operated since 1 Jan 2016 by one single surgeon that were all video documented. The early postoperative period was defined as 12 months after surgery. RESULTS Overall, there were 27 unilateral and 33 bilateral surgical cases of 24 female and 36 male children. The mean age at surgery was 45.25 months (range 1-200 months). The most common intraoperative events were vitreous prolapse and anterior capsule rupture with 28.9% and 13.3%, respectively. Within 12 months of follow-up, five eyes (5.6%) were re-operated because of visual axis reo-pacification (VAR). Intraocular hypertension was diagnosed in seven eyes (7.8%), including two cases that required surgical treatment. In all cases with intra- and early postoperative complications related specifically to bag-in-the-lens technique, it was possible to manage them and successfully implant bag-in-the-lens IOL. CONCLUSIONS Implementation of bag-in-the-lens technique in the treatment of paediatric cataract was associated with a relatively low rate of intra- and postoperative complications, including rare cases of VAR. The correct management of complications related specifically to bag-in-the-lens IOL implantation technique shall to be considered during the learning curve.

Abstract
BACKGROUND To describe factors which influence the age at detection and age at presentation of patients with childhood cataract at a tertiary eye care facility in Southwest Nigeria. METHODS A retrospective review of children who presented with cataract between 2011 and 2015. Case notes were reviewed and data on age at detection and presentation as well as other clinical information was collected and analyzed using Stata 12 statistical software. RESULTS A total of 164 cases were reviewed, 52.4% of them were boys. Median age at presentation was 48 months while the median age at detection was 13.5 months. Seventy-four (45.1%) children had congenital cataract, 31.1% had developmental cataract, and 21.3% had traumatic cataract. The child's mother detected the cataract in 116 (70.7%) of the patients. Median age at presentation for patients with congenital cataract was 18 months and 84 months for developmental cataract. The median age at presentation for congenital cataracts that were noticed by the mother was 17 months compared with 72 months for those noticed by other caregivers (p = 0.0085). The median age at presentation for developmental cataracts that were noticed by the mother was 72 months compared with 114 months for those noticed by other caregivers (p = 0.0065). Gender of the child did not significantly influence the age at detection or presentation. The source of referral and the location of domicile did not significantly affect the time interval between detection of the cataract and presentation to hospital. CONCLUSION The average age of children presenting with cataracts in our setting is older than in high income countries. Detection of the cataract by the mother increases the likelihood of early presentation; thus, focused maternal education may promote earlier detection and presentation.

BACKGROUND The role of optometrists in paediatric visual assessment must compliment the role of other eye-care practitioners at all levels of care. This study was undertaken to determine if optometrists in Ghana screen, diagnose and manage paediatric ocular conditions (for example, strabismus, amblyopia), and further assessed if optometrists in Ghana have the requisite paediatric instrumentation in their practices. METHODS This was a cross-sectional descriptive survey involving optometrists in both public and private eye-care sectors in Ghana. A paediatric visual assessment questionnaire was sent to all registered optometrists in Ghana. The contents of the questionnaire evaluated areas of vision assessment, refraction, and previous diagnosis and management, which were matched with practice characteristics such as location, type of practice and type of employment. Chi-squared statistic was used to test associations between variables. RESULTS Responses were obtained from 140 optometrists out of the 326 registered optometrists, representing a response rate of 46 per cent. Overall, less than half of respondents (64 which represents 46 per cent) assessed themselves as practising full-scope paediatric eye care. These self-assessment views were more common among optometrists at the regional level (111: 79.3 per cent), followed by the district (20: 14.3 per cent) and sub-district levels (nine: 6.4 per cent) (χ2 = 4.774, p < 0.05), but was not influenced by type of employment, type of practice and level of training (p > 0.05). In addition, the study revealed that many respondents were more likely to assess pre-schoolers' visual acuity (VA) (121: 96.0 per cent), do refraction (109: 88.6 per cent) and perform binocular vision (BV) assessment (93: 76.9 per cent) compared to the toddlers' VA (72: 55.4 per cent), refraction (57: 46 per cent) and BV assessment (68: 56.2 per cent). CONCLUSION Full-scope paediatric eye care services among optometrists in Ghana is limited.

Abstract
PURPOSE To compare short-term visual outcomes (best corrected visual acuity [BCVA]), visual axis opacification, anterior (ACCC) and posterior (PCCC) continuous curvilinear capsulorhexis size, shape, and extension, and their decentration between manual capsulorhexis and 25-gauge vitrectorhexis in pediatric cataract surgery with intraocular lens (IOL) implantation. METHODS Thirty eyes of children aged 3 to 8 years with developmental cataract were randomly selected for ACCC and PCCC by manual capsulorhexis forceps and 25-gauge vitrectomy cutter followed by IOL implantation and limited anterior vitrectomy. The size of the ACCC and PCCC was measured intraoperatively with calibrated capsulorhexis forceps. Patients were followed up for 3 months postoperatively and were evaluated for BCVA and visual axis opacification. Slit-lamp photographs of operated eyes were taken in retroillumination. The size in millimeters and decentration of the ACCC and PCCC from the center of the IOL were measured with the help of the Python imaging library. RESULTS There was no statistically significant difference between BCVA (P > .05), visual axis opacification (P > .05), size of the ACCC (P > .05) and its decentration (P > .05), extension of the rhexis (P > .05), and size of the PCCC (P > .05) and its decentration (P > .05) between the two methods. CONCLUSIONS In both groups, BCVA, visual axis opacification, and ACCC and PCCC size, shape, and decentration from the center of the IOL were comparable, making 25-gauge vitrectorhexis a good alternative to manual capsulorhexis.

Abstract
AIM To assess visual acuity outcomes, and factors associated with the outcome, of paediatric cataract surgery at the Child Eye Health Tertiary Facility, Gondar, Northwest Ethiopia. METHODS The medical records of children aged below 16 years who underwent cataract surgery between September 2010 and August 2014 were reviewed for preoperative, surgical and postoperative data. RESULTS One hundred and seventy-six eyes of 142 children (mean age 7.9 years±4.2 SD, 66% male) who had cataract surgery were included. Twenty-five per cent (35/142) of children had bilateral cataract, 18 (13%) had unilateral non-traumatic cataracts and 89 (63%) had unilateral traumatic cataracts. An intraocular lens was implanted in 93% of eyes. Visual acuities at last follow-up: bilateral cases in the better eye: good (≥6/18 or fix and follow) in 21/34 eyes (62%), borderline (<6/18-6/60) in 4 eyes (12%) and poor (<6/60) in 9 eyes (26%). In unilateral non-traumatic cases: good in 6 eyes (33%), borderline in 3 eyes (17%) and poor in 9 eyes (50%). In unilateral traumatic cases: good in 36 eyes (40%), borderline in 20 eyes (23%) and poor in 33 eyes (37%). In bilateral cataract, worse outcomes were associated with preoperative nystagmus/strabismus. In traumatic cases, worse outcomes were associated with the preoperative trauma-related complications. CONCLUSIONS Visual acuity improved significantly after surgery, with better outcomes in bilateral cases. Early detection and surgery by a trained surgeon with good follow-up and postoperative rehabilitation can lead to better visual outcomes.

Abstract
Pediatric cataract is often diagnosed and managed late. This delay may be due to the ignorance on the part of the community, financial constraints, delay in the diagnosis and lack of tertiary care facilities. There is an urgent need to include rubella vaccination in the universal immunization program. A Simple Red Reflex test to detect a cataract and guiding the parent for early intervention will go a long way in achieving the target of eliminating cataract as a cause of childhood blindness. The importance of early detection and quick referral to a multispecialty center can save the child of lot many blind-years. These children have the potential to achieve the best possible visual acuity if managed early.

Abstract
Pediatric cataract is a leading cause of childhood blindness. Untreated cataracts in children lead to tremendous social, economical, and emotional burden to the child, family, and society. Blindness related to pediatric cataract can be treated with early identification and appropriate management. Most cases are diagnosed on routine screening whereas some may be diagnosed after the parents have noticed leukocoria or strabismus. Etiology of pediatric cataract is varied and diagnosis of specific etiology aids in prognostication and effective management. Pediatric cataract surgery has evolved over years, and with improving knowledge of myopic shift and axial length growth, outcomes of these patients have become more predictable. Favorable outcomes depend not only on effective surgery, but also on meticulous postoperative care and visual rehabilitation. Hence, it is the combined effort of parents, surgeons, anesthesiologists, pediatricians, and optometrists that can make all the difference.

Abstract
PURPOSE To determine the characteristics and risk factors for the development of glaucoma after cataract surgery in children seen at a major referral tertiary eye centre in South India. METHODS This is a retrospective review of the medical records of consecutive patients seen at the glaucoma/paediatric eye clinic of the centre, with a diagnosis of glaucoma secondary to aphakia/pseudophakia over a 5-year period. RESULTS There were 21 eyes of 14 children that developed glaucoma and 23 eyes of 12 children were selected as control. The mean age (standard deviation SD) at the time of cataract surgery for the glaucoma group was 7.4 (± 10.1) months and 39.13 (± 41.2) months for the control. The mean follow-up (SD) period was 114.29 (± 61.9) months and 97.61 (± 43.5) months for the glaucoma and control, respectively. The mean duration from cataract surgery to onset of glaucoma was 81.19 (± 52.4) months (median 66 months, range 21-172 months). Multivariate analysis detected age at surgery younger than 12 months (OR 10.45, 95%CI 1.76-62.03, p = 0.010) and ocular anomalies mainly microcornea (OR 7.11, 95%CI 1.14-44.46, p = 0.036) as risk factors for development of glaucoma after paediatric cataract surgery. CONCLUSION Glaucoma can develop several years after childhood cataract surgery. Surgery in the first year of life and microcornea are risk factors for the development of glaucoma post-surgery. Signs of glaucoma should specifically be looked for during follow-up visits.

Abstract
Advances in technology have made surgery in children safer and faster. The management of pediatric cataract has made rapid progress in the past decade with the availability of safer anesthesia, newer technique's, more predictable intraocular lens (IOL) power calculation, a better understanding of neurobiology, genetics, amblyopia management, improved IOL designs for preventing visual axis opacification, and adjuvant postoperative care. Modern vitrectomy machines with minimally invasive instruments, radiofrequency, diathermy, and plasma blades help immensely in complicated cases. Preoperative evaluation with ultrasound biomicroscopy and optical coherence tomography (OCT) allows better planning of surgical procedure. The future holds good for stem cell research, customized OCT, and Zepto (precision pulse capsulotomy).

Abstract
BACKGROUND/PURPOSE To evaluate outcomes in pediatric patients undergoing lensectomy, posterior capsulotomy, and triamcinolone-assisted vitrectomy for congenital cataract. METHODS This retrospective study included 34 patients younger than 72 months who underwent lensectomy, posterior capsulotomy, and triamcinolone-assisted vitrectomy with or without intraocular lens (IOL) implantation for cataract at the National Taiwan University Hospital from July 2006 to December 2012. RESULTS Fifty-one eyes from 34 patients with cataract (unilateral in 17 patients, bilateral in 17 patients) were included. The mean age at surgery was 26.74 months (range: 2-72 months). The mean postoperative follow-up was 27.8 months (range: 6-72 months). Primary IOL implantation was performed in 25 eyes, 21 of which had the IOL implanted in the capsular bag. Fifty eyes had a central round pupil. The median logarithm of the minimum angle of resolution visual acuity was 0.3 in patients with unilateral cataract and 0.1 in those with bilateral cataract. Three eyes (5.9%) developed visual axis opacification (VAO) and required further surgery. Univariate analysis using Fisher's exact test indicated that surgery in the first 12 months of life was significantly associated with development of VAO (p=0.047). The incidence of postoperative VAO was approximately 15.8% in this age group. CONCLUSION Triamcinolone-assisted vitrectomy can be used in pediatric cataract surgery without serious long-term adverse effects. While the incidence of VAO is low, it appears unavoidable in approximately one-sixth of patients who undergo surgery before 12 months of age.

Abstract
αB-crystallin acts as an anti-apoptosis protein in human lens epithelial (HLE) cells. We recently identified a missense mutation in αB-crystallin that changes proline 20 to an arginine (P20R) in a Chinese family with autosomal dominant congenital posterior polar cataract. The impact of the P20R mutation on the anti-apoptosis function remains unclear. To explore the anti-apoptotic activity of αB-crystallin wild type (αB-wt) and its P20R mutant under oxidative stress, HLE cells were transfected with αB-wt and αB-P20R constructs and expression was measured by western blotting. Flow cytometry and terminal deoxynucleotidyl transferase (TdT)-mediated dUTP digoxigenin nick end-labelling (TUNEL) staining were performed to investigate apoptosis. We found that αB-wt performed a dominant role in inhibiting stress-induced apoptosis, but this function was impeded in cells expressing αB-P20R. The P20R mutant of αB-crystallin exhibits diminished anti-apoptotic activity compared with the native protein.

Abstract
The aim of this study was to report feasibility, the visual outcomes and complications of pediatric cataract surgery with primary intraocular lens implantation in children aged 5 to15 years in local anesthesia. This retrospective interventional case series included 62 eyes from 50 children who underwent pediatrc cataract surgery with primary intraocular lens implantation at the Mana eye Clinic Nkongsamba between 2006 and 2015 Main outcome measures were: best-corrected post operative visual acuity, and intraoperative and postoperative complications. Mean age at surgery was 10.18 ± 3.21 years. Mean follow up length was 15.75 ± 3.36 weeks. Etiology included: 10 congenital cataracs (16.12%). 35 developmental cataracts (56.45%) and 17 traumatic cataracts (27.41%). The mean preoperative BCVA was logMAR 1.19 ± 0.33. (range 0.6-2.3). After cycloplegia refraction 2 weeks after surgery, the mean postoperative BCVA was log MAR 0.58 ± 0.88 ( range 0.5-1.8). The mean implanted IOL power was 22.01 ±3.16 D. IOL was succefuly implanted in 54 eyes (87.07%). Eight eyes (9.67%) were left aphakic. Increase in BCVA of 4 logMAR lines and above was recorded in 27 patients (43.55%). Intraoperative complications included: 4 posterior capsule holes with vitrous lost, 3 lenses subluxation and 1 case of iris dialyse. Late postoperative complications included: posterior capsular opacity which occurred in 16 patients, 3 posterior synechia, 2 retinal detachment. Peribulbar anaesthesia can be considered as a viable option in selected patients presenting developmental cataract undergoing cataract surgery in developing countries. Effort should be made to improve the early identification of congenital cataract and its early surgical intervention and prompt optical rehabilitation to prevent amblyopia.

Abstract
Childhood cataract is an avoidable cause of visual disability worldwide and is a priority for VISION 2020: The Right to Sight. There is a paucity of information about the burden of cataract in children and the aim of this review is to assess the global prevalence of childhood cataract. The methodology for the review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We performed a literature search for studies reporting estimates of prevalence or incidence of cataract among children (aged<18 years) at any global location using the Cochrane Library, Medline and Embase up to January 2015. No restrictions were imposed based on language or year of publication. Study quality was assessed using a critical appraisal tool designed for systematic reviews of prevalence. Twenty prevalence and four incidence studies of childhood cataract from five different geographical regions were included. The overall prevalence of childhood cataract and congenital cataract was in the range from 0.32 to 22.9/10000 children (median=1.03) and 0.63 to 9.74/10000 (median=1.71), respectively. The incidence ranged from 1.8 to 3.6/10000 per year. The prevalence of childhood cataract in low-income economies was found to be 0.42 to 2.05 compared with 0.63 to 13.6/10000 in high-income economies. There was no difference in the prevalence based on laterality or gender. This review highlights substantial gaps in the epidemiological knowledge of childhood cataract worldwide, particularly from low and lower middle-income economies. More studies are needed using standard definitions and case ascertainment methods with large enough sample sizes.

Abstract
PURPOSE The purpose of this study was to look at the visual outcomes of bilateral congenital cataract surgery. DESIGN A prospective study was conducted. METHODS A total of 102 eyes of 51 children aged between 2 and 12 months undergoing bilateral congenital cataract surgery from January 2008 to December 2008 with a 3-year follow-up were included in this study. The study was performed at a tertiary public hospital. Data were analyzed using SPSS version 17. Chi-square (χ²) tests were performed to identify the association between visual outcome and age at surgery. P values less than 0.05 were considered statistically significant. RESULTS Among the 102 eyes, 32 (31.4%) eyes were operated on when the subjects were aged between 2 and 3 months, and 70 (68.6%) eyes were operated on at the age of 3 to 12 months. The subjects were followed up for 3 years after surgery. Postoperative best-corrected visual acuity was measured. Visual outcomes were significantly poor in children aged 3 months or older (P < 0.001) as compared with children aged between 2 and 3 months. CONCLUSIONS Early detection and treatment with long-term postoperative rehabilitation is vital to improve visual outcomes of children with congenital cataract.

Abstract
PURPOSE To assess the outcomes of congenital/developmental cataract from a tertiary eye care hospital in Northwest Nigeria. MATERIALS AND METHODS A retrospective chart review was performed of all patients diagnosed with congenital or developmental cataract who underwent surgery from January 2008 to December 2009. Data were collected on patient demographics, preoperative characteristics, intraoperative complications, and postoperative outcomes as well as complications. RESULTS A total of 181 eyes of 102 patients underwent surgery. There were 95 (52.5%) right eyes. There were 64 (62.7%) males. The mean age of the patients was 6.88 ± 7.97 years. Fifty-four (51.3%) patients were below 3 years old. Most (62%) patients had congenital cataract with a history of onset within the first year of life [39 (62.9%) patients]. Amblyopia, nystagmus, and strabismus were the most frequent ocular comorbidities accounting for 50.3%, 36.5%, and 35.4% of eyes respectively. The majority (84.3%) of the patients had surgery within 6 months of presentation. All patients underwent manual small incision cataract surgery (MSICS). Seventy-nine (77.5%) patients underwent simultaneous bilateral surgery. Intraocular lens implantation was performed in 83.4% eyes. The most common early and late postoperative complication was, posterior capsular opacity which occurred in 65 eyes of 43 children. In these cases, moderate visual acuity was predominant visual outcome. CONCLUSION Treatment of pediatric cataract in our setting is complicated by demographic factors which results in late presentation and consequently, late treatment of children. Short-term visual outcome is fair. Data on long term postoperative outcomes could not be acquired due to poor follow-up.

Abstract
Childhood cataracts have become a leading cause of preventable childhood blindness in many areas of the world. Here we summarize regional focus group discussions from the 4th Annual International Congenital Cataract Symposium on the current situation, challenges, and recommendations for the management of congenital cataracts in sub-Saharan Africa, the Middle East and North Africa, South Asia, Central America, South America, and developed nations. Strategies for managing congenital cataracts must be adapted and developed according to regional conditions. A basic framework for acceptable outcomes must focus on developing systems to address the critical components of education, access, quality care, and good follow-up.

Abstract
To determine the avoidable causes of childhood blindness in Malaysia and to compare this to other middle income countries, low income countries and high income countries. Data were obtained from a school of the blind study by Patel et al. and analysed for avoidable causes of childhood blindness. Six other studies with previously published data on childhood blindness in Bangladesh, Ethiopia, Nigeria, Indonesia, China and the United Kingdom were reviewed for avoidable causes. Comparisons of data and limitations of the studies are described. Prevalence of avoidable causes of childhood blindness in Malaysia is 50.5 % of all the cases of childhood blindness, whilst in the poor income countries such as Bangladesh, Ethiopia, Nigeria and Indonesia, the prevalence was in excess of 60 %. China had a low prevalence, but this is largely due to the fact that most schools were urban, and thus did not represent the situation of the country. High income countries had the lowest prevalence of avoidable childhood blindness. In middle income countries, such as Malaysia, cataract and retinopathy of prematurity are the main causes of avoidable childhood blindness. Low income countries continue to struggle with infections such as measles and nutritional deficiencies, such as vitamin A, both of which are the main contributors to childhood blindness. In high income countries, such as the United Kingdom, these problems are almost non-existent.

Abstract
CONTEXT Bilateral pediatric cataracts are important cause of visual impairment in children. AIM To study the outcome of bilateral pediatric cataract surgery in young children. SETTING AND DESIGN Retrospective case series in a tertiary center. MATERIALS AND METHODS Records of pediatric cataracts operated between January 2001 and December 2003, with a minimum follow-up of 3 months, were reviewed retrospectively. STATISTICAL METHODS Independent sample t-test, Fisher's exact test, and logistic regression using SPSS (Statistical Package for Social Science, Chicago, USA) version 12. RESULTS 215/257 (83.7%) patients had a minimum follow-up of 3 months. The mean age of presentation to the hospital was 53 months (range: 0-168 months). Congenital cataract was present in 107 patients (58.2%) and developmental cataract in 77 patients (41.8%). The mean age at surgery was 55.2 months (range: 1-168 months). Out of 430 eyes, 269 (62.6%) had an intraocular lens implanted. The mean duration of follow-up was 13.1 months (range: 3-38 months). Pre-operatively, 102 patients (47.3%) had visual acuity <6/60, in the better eye, compared to 37 patients (17.2%) post-operatively ( P < 0.001). Eighty-five patients (39.5%) had visual acuity >6/18. The most common early post-operative complication was fibrinous uveitis in 57 eyes (13.3%) and the most common delayed post-operative complication was posterior capsular opacification in 118 eyes (27.4%). The most important prognostic factor for poor outcome was congenital cataract (odds ratio [OR]: 26.3; 95% confidence interval [CI], 4.4-158.5) and total cataract (OR: 4.8; 95% CI, 1.3-17). CONCLUSION Nearly half of the eyes had visual acuity >6/18. The outcome was poorer in congenital cataracts, especially those operated after >1 year of age.

Abstract
PURPOSE To compare visual outcome results among traumatic and nontraumatic groups of eyes with cataract in the pediatric age group. METHOD This is a retrospective cohort study. This study comprised a consecutive series of pediatric patients under 5 years of age with unilateral congenital, developing, or traumatic cataract who underwent surgery between January 1999 and April 2012 at Drashti Netralaya, Dahod. Records were retrieved from the medical record department. Patients were grouped as traumatic or nontraumatic and their demographics, cataract type, presenting symptoms, surgical intervention, and postoperative visual acuity follow-up refractive changes were recorded and compared. RESULTS A total of 128 eyes of 128 children under 5 years of age were included with unilateral cataract. A total of 85 (66.4%) were traumatic and 43 (33.3%) nontraumatic. The age at surgery ranged from 1 to 60 months. Eyes were grouped by etiology: group 1- traumatic 85 (66.4%) eyes that had traumatic cataracts. Group 2 non-traumatic 43 (33.3%) eyes that had congenital, developmental or complicated cataracts. The mean follow-up time was 117 days. Finally, 22 (51.1%) group 1 patients and 40 (47.1%) group 2 patients achieved visual acuity better than 20/200 (p = 0.000). CONCLUSIONS Surgical treatment with intraocular lens implantation for children with congenital, developmental, or traumatic cataract is an effective treatment for visual rehabilitation. Visual outcome is significantly better (p = 0.005) in case of nontraumatic cataracts than traumatic cataracts.

Abstract
Background: We compared vision and quality of life (VQL) of children aged 5-15 years and operated for unilateral and bilateral cataract between 2008 and 2010 in western India. Materials and Methods: In this cohort study, ophthalmologists assessed vision, anterior and posterior segment of eyes with cataract. Children completed a functional vision questionnaire (LVP-FVQ). Follow up at 6 months after surgery included the best corrected visual acuity (BCVA), FVQ and eye assessment. The improvement of BCVA and quality of life were compared in group of unilateral and bilateral cataract. Result: A total of 20 (70%) bilateral and 7 (39%) unilateral cataract were operated within 1 month of detection. All 48 eyes with bilateral cataract were congenital and 12 (67%) unilateral cataract were traumatic. Among bilateral group, 27 eyes [56.2% (95% confidence interval (CI) 44.4-72.2)] and in unilateral group 11 eyes [61.1% (95% CI 38.6-83.6)] had vision ≥ 20/60 at 6 months follow up. The visual gain was significantly higher in children who were operated between 1 month and 1 year of detection (adjusted Odds ratio (OR) = 15.6 P = 0.03). Positive impact on VQL in bilateral group was noted in 50%, 27%, and 13% children for subscale of distant vision, near vision, and field of vision, respectively. There was positive impact in these subscales among children with unilateral cataract. Thirty percent eyes with bilateral cataract and 22% of eyes with unilateral cataract improved their vision. Surgery within 1 month of cataract was significant predictor of improved vision (OR = 16.6 P = 0.02). Conclusion: Vision and VQL improved in children with unilateral and bilateral cataract. However, it was better 6 months following surgery in children with bilateral cataract than in children with unilateral cataract.

Abstract
PURPOSE To investigate the cost implications, safety, and refractive outcomes of simultaneous bilateral cataract surgery (SBCS) with intraocular lens implantation in pediatric patients in a developing world setting. METHODS Children aged 3 months to 10 years with bilateral congenital or developmental cataracts who underwent surgery between January 1, 2007, and December 31, 2009, were eligible for inclusion in this retrospective study. Cost data were compared for simultaneous and sequential cases. Postoperative complications and refraction data were analyzed. RESULTS Ninety-six children (192 eyes) were included, 48 in the SBCS group and 48 in the sequential group. The mean age of the SBCS group and the sequential group was 3.4 and 4.7 years, respectively (P = .04). The total estimated surgical cost was $274 per child for SBCS and $344 for sequential surgery, a reduction of 20.3% for cases of SBCS. Fibrin formation of any amount occurred in 52 of 192 eyes (27.1%), 25 in the SBCS group and 27 in the sequential group (P = .75). Twenty-one eyes (10.9%) had additional surgery to remove visual axis obstruction, 14 in the SBCS group and 7 in the sequential group (P = .11). The incidence of early endophthalmitis in all cases of pediatric cataract surgery in an 11-year period was 0.16%. The incidence of anesthetic-related death during the same period was 0.11%. CONCLUSION Bilateral simultaneous pediatric cataract surgery with intraocular lens implantation may be a safe alternative to sequential surgery, with advantages in cost reduction and no difference in sight-threatening complications.

Abstract
PURPOSE To report clinical characteristics and early postoperative outcomes of pediatric cataract surgery with intraocular lens (IOL) implantation from Lahan, Nepal. METHODS Demographics and surgical, preoperative, and postoperative clinical characteristics data were collected and analyzed. RESULTS Of 2,633 eyes with primary IOL implantation, 2,003 eyes were in the non-traumatic group, whereas 630 eyes were from trauma. Median age at surgery was 7 and 9 years in the non-traumatic and traumatic groups, respectively. Boys comprised 74.2% of the non-traumatic and 85.4% of the traumatic cataract patients. Unilateral cataracts accounted for only 7.7% (154 of 2,003) of the non-traumatic group. Average follow-up was 35 days with greater than 6 months follow-up in 134 of 2,633 (5.1%) eyes. Most (68.5% [1,804 of 2,633]) of the lens opacities were described as total cataract. Although early postoperative best-corrected visual acuity improved from the preoperative recording in 95.0% (2,495 of 2,626) of eyes, 78.1% (2,050 of 2,626) remained in the poor (20/100 or worse) category. Median preoperative and early postoperative best-corrected visual acuity was hand motions and 20/200, respectively. CONCLUSION A high-volume cataract surgical center in Lahan, Nepal, is able to provide cost-effective and high-quality pediatric surgery. Most of the patients in this series were noted to have complete cataracts and were boys. Visual improvement was achieved, but excellent visual outcomes were rarely documented due to late referral and inadequate follow-up. Educating families and primary caregivers with regard to the importance of earlier referral and postoperative optical correction and tracking will improve outcomes.

Abstract
PURPOSE To identify mutations in 12 genes in Chinese families with congenital cataracts. METHODS Twenty five families with congenital cataracts involved in this study. The coding exons and adjacent intronic regions of 12 genes were analyzed by cycle sequencing, including the alpha A crystallin (CRYAA), alpha B crystallin (CRYAB), beta A1 crystallin (CRYBA1), beta A4 crystallin (CRYBA4), beta B1 crystallin (CRYBB1), beta B2 crystallin (CRYBB2), beta B3 crystallin (CRYBB3), gamma C crystallin (CRYGC), gamma D crystallin (CRYGD), gamma S crystallin (CRYGS), alpha 3 gap junction protein (GJA3), and alpha 8 gap junction protein (GJA8) genes. Novel variants were further evaluated in 96 normal controls. RESULTS Nine mutations were identified in 10 of the 25 families (40%), including 5 novel (c.350_352delGCT in CRYAA, c.205C>T in CRYAB, c.106G>C in CRYGD, c.77A>G in CRYGS, c.1143_1165del23 in GJA3) and 4 known (c.292G>A in CRYAA; c.215+1G>A and c.272_274delGAG in CRYBA1, and c.176C>T in GJA3). All novel mutations were predicted to be pathogenic and were not present in 96 controls. CONCLUSIONS Mutations in the 12 genes encoding crystallins and connexins were responsible for 40% Chinese families with congenital cataracts. Our results enriched our knowledge on the molecular basis of congenital cataracts in Chinese population.

Abstract
Cataracts (opacities of the lens) are frequent in the elderly, but rare in paediatric practice. Congenital cataracts (in industrialized countries) are mainly caused by mutations affecting lens development. Much of our knowledge about the underlying mechanisms of cataractogenesis has come from the genetic analysis of affected families: there are contributions from genes coding for transcription factors (such as FoxE3, Maf, Pitx3) and structural proteins such as crystallins or connexins. In addition, there are contributions from enzymes affecting sugar pathways (particularly the galactose pathway) and from a quite unexpected area: axon guidance molecules like ephrins and their receptors. Cataractous mouse lenses can be identified easily by visual inspection, and a remarkable number of mutant lines have now been characterized. Generally, most of the mouse mutants show a similar phenotype to their human counterparts; however, there are some remarkable differences. It should be noted that many mutations affect genes that are expressed not only in the lens, but also in tissues and organs outside the eye. There is increasing evidence for pleiotropic effects of these genes, and increasing consideration that cataracts may act as early and readily detectable biomarkers for a number of systemic syndromes.

Abstract
PURPOSE To identify mutations in 6 genes of 9 Chinese families with congenital cataract and microcornea. METHODS Nine unrelated families with congenital cataract and microcornea were collected. Cycle sequencing was used to detect variants in the coding and adjacent regions of the crystallin alpha A (CRYAA), crystallin beta B1 (CRYBB1), crystallin beta A4 (CRYBA4), crystallin gamma C (CRYGC), crystallin gamma D (CRYGD), and gap junction protein alpha 8 (GJA8) genes. RESULTS Upon complete analysis of the 6 genes, three mutations in 2 genes were detected in 3 families, respectively. These mutations were not present in 96 normal controls. Of the three mutations, two novel heterozygous mutations in GJA8, c.136G>A (p.Gly46Arg) and c.116C>G (p.Thr39Arg), were found in two families with congenital cataract and microcornea. The rest one, a heterozygous c.34C>T (p.Arg12Cys) mutation in CRYAA, was identified in three patients from a family with nuclear cataract, microcornea with axial elongation. No mutation in the 6 genes was detected in the remaining 6 families. CONCLUSIONS Mutations in GJA8 and CRYAA were identified in three families with cataract and microcornea. Elongation of axial length accompanied with myopia was a novel phenotype in the family with the c.34C>T mutation in CRYAA. Our results expand the spectrum of GJA8 mutations as well as their associated phenotypes.

Abstract
Childhood blindness has an adverse effect on growth, development, social, and economic opportunities. Severe visual impairment (SVI) and blindness in infants must be detected as early as possible to initiate immediate treatment to prevent deep amblyopia. Although difficult, measurement of visual acuity of an infant is possible. The causes of SVI and blindness may be prenatal, perinatal, and postnatal. Congenital anomalies such as anophthalmos, microphthalmos, coloboma, congenital cataract, infantile glaucoma, and neuro-ophthalmic lesions are causes of impairment present at birth. Ophthalmia neonatorum, retinopathy of prematurity, and cortical visual impairment are acquired during the perinatal period. Leukocoria or white pupillary reflex can be cause by congenital cataract, persistent hyperplastic primary vitreous, or retinoblastoma. While few medical or surgical options are available for congenital anomalies or neuro-ophthalmic disorders, many affected infants can still benefit from low vision aids and rehabilitation. Ideally, surgery for congenital cataracts should occur within the first 4 months of life. Anterior vitrectomy and primary posterior capsulotomy are required, followed by aphakic glasses with secondary intraocular lens implantation at a later date. The treatment of infantile glaucoma is surgery followed by anti-glaucoma medication. Retinopathy of prematurity is a proliferation of the retinal vasculature in response to relative hypoxia in a premature infant. Screening in the first few weeks of life can prevent blindness. Retinoblastoma can be debulked with chemotherapy; however, enucleation may still be required. Neonatologists, pediatricians, traditional birth attendants, nurses, and ophthalmologists should be sensitive to a parent's complaints of poor vision in an infant and ensure adequate follow-up to determine the cause. If required, evaluation under anesthesia should be performed, which includes funduscopy, refraction, corneal diameter measurement, and measurement of intraocular pressure.

Abstract
AIM To determine the causes of childhood blindness and severe visual impairment (BL/SVI) in schools for the blind in Malaysia. METHODS All children ≤ 15 years attending 24 schools for the blind throughout the country were examined using the WHO Prevention of Blindness Programme (WHO/PBL) eye examination record for children, and visual loss was classified according to the International Classification of Disease (ICD). RESULTS In all, 469 children were examined, of whom 448 (95.6%) had BL/SVI. The major causes of visual loss were retinal disorders (n=148, 33%; mainly retinopathy of prematurity (n=78, 17.4%)), cataract/pseudophakia/aphakia (n=77, 17.2%), and anomalies affecting the whole globe. (n=86, 19.2%). The major underlying etiology was undetermined (n = 193, 43.1%), followed by hereditary factors, 21.7% (mainly retinal dystrophies), and perinatal factors, 20.5%. More than 34 (7.6%) cases were considered potentially preventable and 192 (42.9%) potentially treatable. CONCLUSION Diseases of the retina are the major cause of visual impairment, with retinopathy of prematurity being an important avoidable cause. This reflects expansion of neonatal services in Malaysia, and improved survival of very low birth weight and preterm babies. Lens-related causes of visual impairment reflect the need to further improve pediatric ophthalmology services in Malaysia.
