Abstract
Purpose To study and describe clinical characteristics of congenital and developmental cataract at a tertiary eye care facility. Methods In this retrospective study, 942 children (1311 eyes) presenting with congenital/developmental cataract over a 10-year study period were included. Gender, age at surgery, main presenting complaint, morphologic type of cataract, laterality, family history, and associated findings were recorded. Results The overall proportion of boys and girls undergoing cataract surgery was approximately equal (P = 0.110). However, in the cases of bilateral cataract, the proportion of boys was larger than girls (P = 0.028). More than half (62.3%) of the patients underwent surgery at the age of >3 years. The main presenting complaint was white pupils, accounting for 48.1% of cases. Total cataract was the most common morphologic type in all age groups. In total, 133 children out of 942 (14.1%) had a positive family history of congenital/developmental cataract. Strabismus and nystagmus were seen in 27.2% and 19.3% of the eyes, respectively. Additional ocular dysmorphology was found in 97 (10.3%) of patients. Coexisting systemic disease was found in 149 (15.8%) cases. Among syndrome-associated cataracts, Down syndrome accounted for the majority of cases. Conclusion High prevalence of total cataracts as well as frequent association with strabismus and nystagmus are likely to be the consequences of delayed presentation.

Abstract
BACKGROUND AND OBJECTIVES Congenital cataract is a condition compromising the eye's crystalline lens in infants and is usually diagnosed at birth. It can lead to irreversible vision loss if not promptly detected and treated, especially in unilateral cases. Nowadays, children with congenital cataracts can undergo surgical removal of their opacified crystalline lenses, and visual rehabilitation is mandatory to prevent deep amblyopia. Contact lenses, predominantly of rigid gas-permeable (GP) type, are gaining more popularity for this matter. METHOD In this retrospective cohort study, unilateral aphakic children younger than 6 years referred to the Contact Lens Clinic at Farabi Eye Hospital from November 2011 to September 2019 were included. RESULTS Seventy-six unilateral aphakic children with congenital cataracts (57.9% boys and 42.1% girls) rehabilitated with GP were studied. The mean age of diagnosis and referral to the contact lens clinic were 20.0±19.8 and 32.0±24.4 weeks, respectively, while the mean follow-up time was 12.44±26.28 months. The mean visual acuity for children capable of cooperating at the last follow-up was 0.98±0.62 log MAR. Among the participants, eight children (9.7%) were diagnosed as glaucoma suspects. The mean initial base curve and power of GP lenses were 7.86±0.39 mm and 23.29±5.52 diopters, respectively. Only 21 parents (27.6%) reported nonadherence to the scheduled part-time patch program. CONCLUSION The results of this study showed GP-based optical treatment after early diagnosis, surgical removal of congenital cataracts, and a long-term close follow-up to be well tolerated by children and their parents, with acceptable parents' compliance and can thus be introduced as a safe and effective method to achieve desirable visual outcomes.

Abstract
PURPOSE To report the surgical outcomes of children with cataract associated with microphthalmia, microcornea, or persistent fetal vasculature (MMP) and children with isolated cataract. METHODS The study included 111 children (cataract associated with MMP: n = 25) who underwent cataract surgery at younger than 16 years. Exclusion criteria were duration of follow-up less than 5 years, intraindividual differences in age at surgery, eye disorders other than MMP, secondary cataract, and syndromal diseases. Main outcome measures were proportion of eyes with glaucoma and best corrected visual acuity (BCVA). Both groups were dichotomized by age at surgery (early intervention group: ≤ 48 days). Descriptive analysis was performed throughout. RESULTS Median age at surgery was 3.9 months for cataract associated with MMP and 23.3 months for isolated cataract. The median (interquartile range [IQR]) duration of follow-up was 95.9 months (range: 76.0 to 154.5 months). In children with bilateral cataract associated with MMP, the proportion of eyes with final BCVA worse than 0.3 logMAR was similar regardless of age at surgery (early intervention: 80%, later intervention: 78%). In bilateral isolated cataract, the proportions were 56% and 33%, respectively. Children with cataract associated with MMP had a high prevalence of glaucoma (28%). Glaucoma prevalence was lower in the later intervention group. CONCLUSIONS In the presence of MMP, early cataract surgery is associated with a high risk of post-lensectomy glaucoma, but does not offer the benefit of better visual outcomes.

THE LANCET CHILD & ADOLESCENT HEALTH 2018; 2:863-871. [PMID: 30389448 DOI: 10.1016/s2352-4642(18)30317-1] [Citation(s) in RCA: 72] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Revised: 09/28/2018] [Accepted: 09/28/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND International initiatives to prevent childhood blindness have highlighted the importance of early, effective intervention for congenital and infantile cataract. In the UK, intraocular lens implantation has been widely adopted by surgeons to treat these conditions. However, evidence about the benefits and risks of this technique in different age groups is limited. The IoLunder2 study assessed outcomes following primary intraocular lens implantation in children aged 2 years and younger with congenital or infantile cataract. METHODS The IoLunder2 study was a prospective observational cohort study done at 31 sites in the UK and Ireland. Eligible children were aged 2 years or younger who had cataract surgery concurrently with intraocular lens implantation or conventional treatment (aphakic correction with contact lenses or glasses) after cataract surgery between Jan 1, 2009, and Dec 31, 2010. Children with significant ocular comorbidity precluding lens implantation, defined by the presence of complex persistent fetal vasculature, other ocular structural anomalies, severe microcornea (horizontal corneal diameter <9·5 mm), or severe microphthalmos (axial length <16 mm), were excluded from the analysis of the key outcomes. Postoperative visual rehabilitation was assessed at 1, 3, and 5 years after surgery with a 4m logarithm of the minimum angle of resolution (logMAR) notation test. Best corrected visual outcome (acuity) overall was assessed 5 years after surgery for children with bilateral and unilateral cataract. We also used multivariable logistic and linear regression to model the association between intraocular lens implantation and outcomes of interest (vision, glaucoma, and visual axis opacity). FINDINGS A total of 256 eligible children were recruited; two had incomplete data and were excluded. 158 of the 254 included children (102 [65%] with bilateral cataract and 56 [35%] with unilateral cataract) had no significant ocular morbidity and were analysed for the key outcomes. Primary intraocular lens implantation was done in 88 (56%) of 158 children (50 children with bilateral cataract and 38 children with unilateral cataract). 70 (44%) of 158 children had conventional treatment (52 with bilateral cataract and 18 with unilateral cataract). Overall median visual acuity at 5 years was 0·34 logMAR (IQR 0·20-0·54) for children with bilateral cataract and 0·70 logMAR (IQR 0·3-1·3) in the operated eye for children with unilateral cataract. Primary intraocular lens implantation was not associated with better visual outcome than conventional treatment in children with bilateral cataract (adjusted coefficient -0·1, 95% CI -0·5 to 0·3, p=0·48) or unilateral cataract (adjusted coefficient -0·3, -0·6 to 0·2, p=0·36), or reduced incidence of postoperative glaucoma in children with bilateral cataract (adjusted odds ratio [OR] 0·5, 0·10 to 1·80, p=0·28), but was associated with a five times higher risk of reoperation for visual axis opacity requiring general anaesthesia in children with bilateral cataract (adjusted OR 5·94, 95% CI 2·14-16·47, p=0·001) and a 20 times higher risk in children with unilateral cataract (20·15, 3·01-134·00, p=0·001). INTERPRETATION The findings of this cohort study indicate that intraocular lens implantation does not confer better vision or protection against postoperative glaucoma, and conversely increases the risk of requiring early reoperation in children younger than 2 years with bilateral or unilateral cataract. The routine use of intraocular lens implantation in this age group cannot be recommended. FUNDING National Institute for Health Research, Ulverscroft Foundation, and the Academy of Medical Sciences.

Abstract
Purpose To determine and to analyze the outcome of pediatric cataract surgery. Methods A retrospective chart review of individuals aged up to 10 years who underwent cataract surgery between January 1, 2004, and December 31, 2014, at the UniversityHospital Zurich, Switzerland. Results 63 children (94 affected eyes) with bilateral (68/94) or unilateral (26/94) cataract were identified. Surgery was performed at a median age of 1.5 months (IQR: 1.3–2.6 months) for the aphakic group (45/94) and of 50.7 months (IQR: 38.0–78.4 months) for the IOL group (49/94). At the last follow-up visit (median 31.1 months, IQR: 18.4–50.2 months), visual acuity was better in bilateral than in unilateral cataract cases. Posterior capsular opacification (PCO) was diagnosed in 30.9% of eyes without a significant difference in the IOL and aphakic groups (p = 0.12). Aphakic glaucoma was diagnosed in 12/45 eyes at a median of 6.8 months (IQR 2.1–13.3 months) after surgery. Microcornea (5/12) and anterior segment anomalies (8/12) were associated with glaucoma development (p < 0.05). Conclusion Laterality and timing of surgery influence the outcome of pediatric cataract surgery. PCO was the most frequent postoperative complication. Aphakic glaucoma is often associated with ocular developmental abnormalities and a poor visual outcome.

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
Congenital cataract is a leading cause of visual deprivation which can damage the developing visual system of a child; therefore early diagnosis, management and long-term follow-up are essential. It is recommended that all neonates be screened by red reflex examination at birth and suspected cases be referred to ophthalmic centers. Early surgery (<6 weeks of age, based on general neonatal health) is important for achieving the best visual outcome particularly in unilateral cases. In bilateral cases, surgery is highly recommended before appearance of strabismus or nystagmus (<10 weeks of age) with no longer than a one-week interval between the fellow eyes. Parents should be informed that surgery is a starting point and not the endpoint of treatment. Appropriate postoperative management including immediate optical correction in the form of aphakic glasses or contact lenses, or intraocular lens (IOL) implantation at the appropriate age (>1 year) is highly recommended. After surgery, amblyopia treatment and periodic follow-up examinations should be started as soon as possible to achieve a satisfactory visual outcome. Practitioners should consider the possibility of posterior capsular opacity, elevated intraocular pressure and amblyopia during follow-up, especially in eyes with microphthalmia and/or associated congenital anomalies. All strabismic children should undergo slit lamp examination prior to strabismus surgery to rule out congenital lens opacities. From a social point of view, equal and fair medical care should be provided to all children regardless of gender.
