Abstract
Purpose: To assess the clinical effects of Grid laser photocoagulation in Diabetic macular edema.
Materials & Methods: A total of 100 eyes of 50 patients with Diabetic Macular edema attending the Department of Ophthalmology at Rajah Muthiah Medical College and Hospital, Chidambaram were the target population of the study. Visual acuity for all patients was evaluated by Snellen’s chart. Baseline BCVA was ≥ 6/60. Macular Grid laser photocoagulation was done for all the patients using 532nm Diode pumped solid state laser (DPSS) delivered by Slit lamp by modified ETDRS criteria. Patients were followed up for a period of 3 months.
Results: Among the 50 patients 26 were Male (52%) and 24 were Female (48%). The mean age of the study population was 55yrs. The mean BCVA BE of the patients; Pre & Post laser showed no change (p > 0.5). On 3 month follow up, 86% of eyes had a stable vision, 4% had improved vision of 1 line and 10% showed decreased vision of 1 line in Snellen’s chart.
Conclusion: Diabetic macular edema is a potentially sight threatening complication of people affected by DM worldwide. Grid laser photocoagulation reduces the risk of moderate vision loss when treated early.
