Anatomical and visual outcomes after two-port pars plana vitrectomy reoperation under silicone oil for epimacular membrane or recurrent retinal detachment.

PURPOSE To describe the anatomical and visual outcomes in a series of patients undergoing two-port pars plana vitrectomy reoperation under silicone oil for recurrent retinal detachment (RD) due to proliferative vitreoretinopathy or epimacular membrane (EMM) after RD repair. METHODS This study is a prospective, consecutive, interventional case series of patients presenting with recurrent RD or EMM under silicone oil. Two-port 25-gauge pars plana vitrectomy reoperation without an infusion port was performed in all cases. RESULTS Thirty-nine patients were included. Reoperation pathology included recurrent RD with proliferative vitreoretinopathy (n = 33) and EMM alone (n = 6). The mean number of previous retinal surgeries was 2.4 ± 1.1 (range, 1-5). The mean overall follow-up was 24 ± 3.7 months. The mean visual acuity change from baseline at final follow-up was an improvement of 0.74 ± 0.63. Macular reattachment was achieved in 29 of 33 patients with RD, and EMMs were successfully removed in all patients. CONCLUSION Two-port pars plana vitrectomy reoperation is an efficacious method for repair of consecutive RD due to proliferative vitreoretinopathy or EMM in patients with previous RD repair with silicone oil. Significant visual improvement with a low complication rate may be achieved in patients with advanced proliferative vitreoretinopathy or EMM under silicone oil.
