Efficacy of Treatment of Diabetic Macular Edema through Frequency-Doubled ND:YAG Laser (532NM) Green Laser

Abstract

Objective: To determine the efficacy of Frequency-doubled Nd: YAG laser (532 nm) green laser in treatment of diabetic macular edema Study Design: This is a descriptive case series study. Setting: Study carried out at Ophthalmology Department, Shaheed Mohtarma Benazir Bhutto Medical University Larkana, from 01-10-2019 to 31-03-2020 (06 months). Materials and Methods: The patients with diabetic macular edema and were advised focal laser photocoagulation with help of frequency doubled Nd: YAG laser (532 nm) green laser. Improvement in visual acuity >2 lines after 3 months on snellen’s chart from the baseline was labeled as efficacy positive. Results: The total of 150 patients were included to assess efficacy of frequency doubled Nd: YAG laser (532 nm) green laser in treating diabetic macular edema as a result improvement in visual acuity of 98 (65.33%) and no improvement or same vision in 52 (34.67%) patients was observed. Conclusion: It is to be concluded that frequency doubled Nd: YAG laser (532 nm) green laser is an effective, useful and non-invasive diagnostic tool in treating diabetic macular edema.
