Outcomes and Complications of In-Office Laser Demarcation of Peripheral Rhegmatogenous Retinal Detachments.

Background and objective To evaluate the outcomes of in-office laser demarcation (LD) for peripheral rhegmatogenous retinal detachments (RRDs). Patients and methods This was a retrospective analysis of peripheral RRDs treated with LD. Patient demographics, visual acuity (VA), and RRD characteristics were recorded. Complications requiring additional procedures were recorded. Multiple logistic regression was used to characterize the association of RRD anatomy to treatment complications. Results A total of 112 eyes of 107 patients were analyzed with mean follow-up of 20 ± 12 months. VA at baseline and last follow-up was equivalent (0.16 logMAR, Snellen equivalent 20/29). Ninety-five (84.8%) eyes were successfully treated without an additional procedure. In multivariate analysis, the presence of VH (odds ratio [OR] = 4.0; 95% confidence interval [CI], 1.1-17; P = .04) and RRDs in the inferior 6 clock hours (OR = 6.2; 95% CI, 1.5-29; P = .01) were associated with complications. Conclusions LD is successful in treating peripheral RRDs. RRD characteristics less conducive to laser include presence of VH and inferior RRD.
