ABSTRACT
OBJECTIVE: The purpose of this study was to evaluate the 1-year incidence of retinal tear or retinal detachment following 23-gauge pars plana vitrectomy (PPV) for epiretinal membrane (ERM), macular hole (MH), or vitreomacular traction (VMT). METHODS: A retrospective chart review of all patients who underwent 23-gauge PPV for ERM, MH, or VMT between January 1, 2007, and December 31, 2007, was performed. Inclusion criteria included age greater than 50 years and absence of other significant ocular pathology. Exclusion criteria included confounding retinal pathology, laser treatment at the time of surgery, previous laser treatment of the retina, or previous PPV. RESULTS: A total of 272 eyes of 268 patients were eligible for inclusion: 159 eyes (58%) had the diagnosis of ERM; 108 (40%) had MH; and 5 (2%) had VMT. The average patient age was 70 years. Of the patients, 15 required additional surgery related to persistent macular pathology within 1 year (5 with ERM, 10 with MH). The incidence of retinal detachment after surgery was 1.1% (3 eyes of 3 patients). The mean time duration prior to development of retinal detachment was 159 days (range, 19 to 333 days). CONCLUSIONS: The 1-year incidence of rhegmatogenous retinal detachment post 23-gauge vitrectomy for repair of macular pathology without prophylactic laser of sclerotomy sites is approximately 1%.
