Abstract
Cataract is a significant cause of visual disability in the pediatric population worldwide. Early diagnosis and prompt surgical intervention is critical to prevent irreversible amblyopia. Ocular evaluation, including the onset, duration, and morphology of cataract is essential to determine the timing for surgical intervention The aim of the study was to study the prevalence, the epidemiological aspects and clinical profile of pediatric cataract in Mansoura ophthalmic center, Mansoura University, Dakahlia, Egypt.This retrospective, analytical study was conducted on children attending Mansoura Ophthalmic Center, Mansoura University, Egypt within the period from January 2016 to January 2021. The study Included all children (≤18 years) diagnosed with cataract and underwent cataract extraction with or without IOL implantation. 124 patients of pediatric cataract were included in this study after fulfillment of the inclusion criteria. Their mean age was 7.6 years and ranged from 2 months to 17 years; 8.1% aged 2 to 6 months, 14.5% aged 6 months to 2 years, 23.4% aged from 2.5 to 6 years and 54% aged from 7 to 17 years. They were 81 males (65.3%) and 43 females (34.7%).The present study showed that 41.3% of cases had congenital cataract, 53.1% had traumatic cataract and 5.6% had complicated cataract. 30.3% had total cataract, 15.1% had anterior polar cataract, 13.6% had posterior polar cataract, 12.1% had lamellar cataract, 9.0% had nuclear cataract, 7.5% had blue dot cataract, and 9.0% had nuclear and posterior subcapsular cataract. Most of cases were free of nystagmus or strabismus (86.2% (. While 2.5% had nystagmus. Exotropia was found in 5.0%; esotropia was found in 6.2%. examination of the studied cases was done using slit lamp without anesthesia in 62.5% and under general anesthesia in 37.5% of all studied cases. Among all studied cases, 71% had unilateral cataract, while 29% had bilateral cataract.Anterior chamber examination showed that 85.0% were normal depth with normal content, 5.0% had anterior and posterior synechiae, 1.2% had iris atrophy, 1.8% had iridodialysis, 1.2% had persistent pupillary membrane, 5.6% had lens matter in anterior chamber. Posterior segment examination showed that it was normal in 86.8% of all studied cases, 8.7% had tigroid fundus. Other findings included myopic changes, pale optic disc, PHPV, retinal hemorrhage.All studied cases were subjected to B-scan ultrasonography, most of them were normal (91.8%), vitreous opacity in 2.5%, opened posterior capsule in 4.3%, minimal vitreous Hge in 0.6% and epiretinal membrane in 0.6% Treatment mainly was surgical approaches, anterior approach in 88.7% and posterior approach in 11.2%. Out of those subjected to anterior approach, 50.6% with vitrectomy and 38.1% without vitrectomy. 74.3% were associated with IOL implantation and 25.6% without IOL implantation. Special steps in certain cases were used as iridoplasty in (2.5%) and Synechiolysis in (11.2%) of the cases. Limitation of the study:The limitations of this study include the retrospective design and the relatively small sample size, this is take of insufficient data and inability to collect all the needed information during the follow up of the patients.
