Retinal Detachment and Epiretinal Membrane Development in Fellow-Eye Laser Prophylaxis
Maxwell J. Wingelaar, Bradley T. Smith- General Medicine
Purpose: To determine the safety and efficacy of fellow-eye laser prophylaxis (FELP) in reducing the rate of retinal detachment (RD) in patients undergoing repair of a primary RD. Methods: Retrospective data were collected on the fellow eyes of consecutive patients undergoing primary RD repair. Patients lacking peripheral retinal pathology in the fellow eye or with less than 3 years of follow-up were excluded. Ninety-eight consecutive patients were identified who underwent FELP as compared with 28 who did not. No patient had symptoms in their fellow eye upon presentation. Rates of RD and epiretinal membrane (ERM) formation in the treatment group were compared with the control group. Results: Three of 98 (3.1%) patients developed RD despite having FELP compared with 5 of 28 (17.9%) in the control group ( P = .005). In the FELP group, 16 (16.3%) patients developed ERM vs 7 of 28 (25.0%) in the group that did not receive prophylactic laser ( P = .29). No patients in either the FELP or control group required surgery for ERM. Conclusions: Prophylactic laser to the fellow eye of patients undergoing primary RD repair reduced the risk of RD without significant risk of ERM formation.
