Two Hours vs Six Hours Occlusion Regimen: A Comparative Study for Anisometropic Ambylopia
Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 10
Abstract
Aim: To compare two hours vs. six hours occlusion regimen in moderate anisometropic amblyopia in combination with one hour near vision activities in children aged 4-9 years. Materials and Methods: a cross sectional study was conducted in the department of Ophthalmology, ASCOMS for a period of six month post refractive error correction involving 30 children aged 4-9 years with moderate anisometropic amblyopia. The children were randomly divided into two equal groups: Group A was put on two hours occlusion of the better eye and Group B on six hours occlusion per day along with one hour of near vision activities. The data was analyzed by paired T-test method. Results: The visual acuity in both the groups showed significant improvement, the mean LogMAR BCVA in Group A improved from 0.39 to 0.12 and Group B showed improvement from 0.40 to 0.12 respectively, both the difference being stastically significant (p=0.001) respectively. However, no significant difference was observed between Group A and Group B in post occlusion visual acuity after six months of follow up.(p=1.000) Conclusion: In moderate anisometropic amblyopia, both two and six hours of occlusion after refractive error correction and when combined with one hour near vision activities produce equivalent amount of improvement in children of younger age group (4-9 years) provided there is good compliance.
