PURPOSE: To evaluate the incidence of retinal redetachment after the removal of silicone oil endotamponade for complicated retinal detachment and identify possible factors affecting outcome. METHODS: This is a retrospective review of 173 patients who underwent pars plana vitrectomy with silicone oil tamponade for complex retinal detachment and subsequent removal of silicone oil (ROSO). The outcome factors studied included anatomical success, best-corrected visual acuity and intraocular pressure pre- and post-ROSO. RESULTS: Anatomical success was achieved in 167 of the 173 eyes (96.5%) after ROSO. The mean duration of silicone oil tamponade was 70 ± 48 weeks (median, 56 weeks; mode, 48 weeks). The cause for primary retinal detachment was proliferative diabetic retinopathy in 36 (20.8%) and proliferative vitreoretinopathy in 137 of 173 cases (79.2%). Best-corrected visual acuity of greater than 20/100 was achieved in 83 cases (49.4%) at 3 months after ROSO. Levene's test for equality of variances was used to determine the association between previous unsuccessful retinal surgeries and redetachment (P = 0.523) and between duration of endotamponade and anatomical success (P = 0.451). CONCLUSION: The incidence of retinal redetachment after ROSO in our study was 3.46%. Aggressive removal of the vitreous base, performing retinotomies, ensuring complete silicone oil filling for adequate tamponade, and argon retinopexy can lead to low complication rates and improved outcomes.
