Abstract:

Objective: To study the effects of supervisedocclusion treatment for amblyopia in children aged 5-9 years. Design: Descriptive Study. Place &Duration: Military Hospital, Rawalpindi (Aug, 2001 to June, 2002). Materials and Methods: Fifty childrenwho failed to respond occlusion therapy previously, were given two weeks of supervised intensive occlusiontherapy for 09 hours daily during waking hours directly under staff supervision. Visual acuity of amblyopicand fellow eye was recorded at each clinic visit before admission, daily during admission and at eachoutpatient visit after discharge. Appropriate spectacles have been prescribed. Visual acuity was recordedusing Snellen chart. After discharge visual acuity was checked at 1 week, 2 weeks, 1 month and at mostrecent clinic visit if still receiving treatment or at final clinic visit if discharged. Results: Depending uponthe age and improvement of the visual acuity after two weeks of occlusion therapy we have divided thepatients into two groups. Group-1 between 5-7 years of age included 37 patients showed an improvement of3-4 lines of the visual acuity. Group – 2 between 7-9 years of age included 13 patients showed animprovement of 1-2 lines. Conclusion: The acuity of amblyopic eyes did not improve without effectivetreatment. Subsequent supervised occlusion therapy was effective in majority of children.
