Brief Summary

Lacunae in Knowledge No study is available in literature regarding visual field impairment in proliferative diabetic retinopathy comparing conventional double frequency Nd:YAG panretinal photocoagulation with PASCAL panretinal photocoagulation AIMS \& OBJECTIVE

1. 1.To compare visual field impairment in conventional double frequency Nd: YAG panretinal photocoagulation with PASCAL panretinal photocoagulation.
2. 2.To examine the effect of these modalities of laser on macular edema
