Abstract:
Correlation between delay time of surgery of congenital cataract and postoperative visual acuity:Introduction: Worldwide, child cataract is 1 to 15 cases per 100,000 children are diagnosed. In the International Classification of Diseases, pediatric cataracts are classified as congenital (Q12) and developmental (H26.0). Congenital cataract occurs in 1–3 out of 10,000 children, and if diagnosed, surgery is required without delay. International researchers report that congenital cataracts require semi-emergency surgery. It is also recommended that children with congenital cataracts be diagnosed after 3 months of age without surgery. Congenital cataracts are recommended for surgery in one eye within 6 weeks and in both eyes within 10 weeks. Early detection of congenital cataracts and emergency surgical treatment are important to improve postoperative visual outcome and quality of life. To investigate the correlation between the surgical delay time and postoperative visual acuity in children diagnosed with congenital cataracts.
Material and methods: This study conduct based on the ophthalmic surgery department of the National Center for Maternal and Child Health, performed for a retrospective longitudinal study design. The study examined cases of congenital cataracts in both eyes and retrospectively follow patients who had congenital cataract surgery in 2018-2020 from the onset of symptoms to the postoperative period. The sample size was calculated using open.epi. We sampled participants for non-probabilistic purposes. The study included children 1 year of age and younger or with nystagmus, cataract with nuclear and polar morphology , and bilateral cataracts Statistical analysis was performed using STATA 16.0 software. The risk of delay time to visual acuity was determined by an ordinal regression model.
Results: The study included 46 cases of congenital cataracts, under the age of 16. 61 percent of the children were male and 58.7 percent were from rural areas. The postoperative visual acuity of the children in the study was <0.09 in 52.2% (n = 24) and 0.1
