Abstract

Aim-to evaluate the outcome of simultaneous & sequential patching in unilateral amblyopia

Method-102 children with unilateral amblyopia (VA- 20/40-20/200), age 3-12 years were evaluated prospectively. Visual acuity (VA), Interocular difference & stereopsis were measured. Patients (51 in each group) were grouped as simultaneous treatment (concurrent glasses & patching at first visit)or sequential treatment (glasses alone at first visit followed by patching at subsequent visit)

Result-Mean VA improved similarly between both the groups. Patients without stereopsis at 1st visit had better stereopsis with sequential treatment compared to simultaneous treatment (p ≤ 0.05)

Conclusion-VA improved approximately 4 lines regardless of treatment type.For children without stereopsis at first presentation, sequential patching yielded better stereopsis outcome proving that the uninterrupted spectacle correction helps to stimulate binocular fusion, fostering binocularity& an appreciation of stereopsis
