Role of Panretinal Photocoagulation in Improvement of Visual Acuity of Patients with Proliferative Diabetic Retinopathy

Abstract

Objective: To determine the improvement of visual acuity in patients having proliferative diabetic retinopathy undergoing panretinal photocoagulation therapy. Study design: This is a descriptive case series study. Setting: Study carried out at Ophthalmology Department, ShaheedMohtarma Benazir Bhutto Medical University Larkana, from 01-10-2019 to 31-03-2020 (06 months). Materials and methods: We selected patient with proliferative diabetic retinopathy from the retina clinic after taking a careful history and clinical examination including visual acuity anterior and posterior segment examination and then patient selected for panretinal coagulation with the  help of frequency-doubled Nd: YAG laser in three or four sittings. Results: The total of 158 eyes of 110 patients with proliferative diabetic retinopathy were included in this study out of which improvement of visual acuity was found in 38 (24%) eyes and 120 (76%) eyes have no improvement or same vision. Conclusion: Proliferative Diabetic Retinopathy (PDR) can successfully be treated with panretinal coagulation with the help of frequency doubled Nd: YAG laser therapy.
