Purpose: To compare baseline biometry measurements in eyes with pediatric cataract versus age-matched controls METHODS: This is a cross-sectional study conducted at a tertiary care hospital that included two arms-prospective arm to collect data from normal eyes and retrospective arm for eyes with pediatric cataract. In the prospective arm, biometry measurements were obtained in healthy children aged 0 to 10 years. Children under the age of four had measurements under anesthesia for an unrelated procedure, while older children had in-office measurements using optical biometry. For comparison, biometric data was collected in children with pediatric cataract through record review. One eye of each patient was randomly selected. Axial length (AL) and keratometry (K) were compared by age and laterality. The medians were compared using Wilcoxon rank-sum tests and variances using Levene's test., Results: There were 100 eyes in each arm, 10 eyes in each age bin of 1-year interval. There was more variability in baseline biometry in eyes with pediatric cataract and a trend for longer AL and steeper K in cataract eyes than aged-matched controls. The difference in AL means was significant in age group 2-4 years, and variances were significant across all age groups (p=0.018). Unilateral cataracts (n=49) showed a trend toward greater variability in biometry than bilateral cataracts, but this did not reach statistical significance., Conclusion: Baseline biometry measures are more variable in eyes with pediatric cataract compared to age-matched controls with a trend toward longer AL and steeper K., (© 2023.

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., (© 2022.

Purpose: This study aims to report long-term outcomes of secondary intraocular lens (IOL) implantation after early cataract surgery in children., Methods: This is a retrospective case series that included children undergoing secondary IOL implantation. The patients had either in-the-bag (ITB) or sulcus implantation; alternative methods of IOL fixation were excluded. Single-piece acrylic IOL was used for ITB and 3-piece acrylic or PMMA IOL for sulcus implantation. The visual acuity outcomes and rate of complications at the last follow-up visit were evaluated., Results: One hundred six eyes (70 patients) were analyzed. The mean follow-up was 5.5 ± 3.8 years. Sixty-two eyes (58.5%) had ITB; 44 eyes (41.5%) had sulcus IOL. All but 3 eyes (97.2%) showed stable or improvement in visual acuity. Early inflammation > grade 2 + was noted with sulcus IOL (84% vs 34%, p = 0.01); late inflammation requiring vitrectomy occurred in one eye with sulcus IOL. Mild decentration was seen in 2 eyes with sulcus IOL; one additional subluxed sulcus IOL was exchanged. Sixteen out of 106 eyes (16%) had glaucoma. Eyes that developed glaucoma had early primary surgery (mean, 0.2 years, p < 0.001, significant); there was no difference in glaucoma rates based on implantation site., Conclusion: Early postoperative inflammation is higher in eyes with sulcus implantation, but good visual acuity outcomes are noted after secondary IOL implantation in children. Glaucoma is the main complication that requires close monitoring and is associated with early age at primary surgery., (© 2021.
