Impact of Monocular Enucleation on Functional Vision in Retinoblastoma Patients

Introduction:Purpose is to assess the impact of monocular enucleation in children with retinoblastoma on the development of their functional vision Methodology: Children diagnosed with retinoblastoma during 2018-2023 in Pediatric Ophthalmology Services in Tertiary Hospital, Lahore, Pakistan and underwent monocular enucleation & completed their chemotherapy were enrolled in this study.Functional vision of patients was assessed on a self-developed proforma.According to the age at the time of enucleation, the children were divided into 2-groups (Group A: 1-5years & Group B: 5.1-10 years).Quantitative variables were analyzed in terms of mean S.D. Results:Out of the 44 children included in the study, 24 were aged 1-5 years, and 20 were aged 6-10 years.Functional vision assessment revealed, 34% had very good and only 6.8% showed very poor ability of primary functions of vision.In Group A, 2.3% of the patients showed "very good" contrast and depth perception while 29.5% showed only "acceptable" primary cardinal components of visual function.In contrast, 5% showed a "very good" response to depth perception while 80% were "good" and 15% had "acceptable" ability in the older age group (Group B).Moreover, in group B, 60.9% demonstrated "good" ability of secondary functions of vision.With regards to Visual fields, only 8.7% had a "very good" visual field while 28.3% showed "acceptable" visual fields in Group A, contrarily 15% showed "very good" response and 20% showed having "acceptable" visual fields in Group B.
