PURPOSE: To evaluate the role of first operation anatomic success compared with success after reoperation and preoperative characteristics in achieving ambulatory vision (≥4/200) and good vision (≥20/100) after repair of complex retinal detachment with vitrectomy and silicone oil tamponade. METHODS: A prospective, observational, multicenter study of patients who underwent vitrectomy with silicone oil for retinal detachments associated with cytomegalovirus necrotizing retinitis or a non-cytomegalovirus necrotizing retinitis etiology, including proliferative diabetic retinopathy, giant retinal tear, proliferative vitreoretinopathy, and ocular trauma. RESULTS: A higher rate of ambulatory vision was achieved in the first operation anatomic success cases, compared with the reoperation cases, for eyes with cytomegalovirus necrotizing retinitis (72% vs 50%, P < 0.01) and eyes without cytomegalovirus necrotizing retinitis (51% vs 38%, P = 0.04). For eyes with cytomegalovirus necrotizing retinitis, preoperative ambulatory vision (RR = 2.3, P < 0.0001) and reoperation (RR = 0.4, P = 0.05) were independent predictors of postoperative ambulatory vision. For eyes without cytomegalovirus necrotizing retinitis, preoperative ambulatory vision (RR = 4.0, p < 0.0001) and retinal detachment etiology (P = 0.02) were prognostic factors. Compared to eyes with trauma, eyes with giant retinal tear, proliferative vitreoretinopathy and proliferative diabetic retinopathy were 2.8 (P < 0.003), 2.2 (P = 0.01) and 1.6 (P = 0.17) times as likely to achieve postoperative ambulatory vision, respectively. Within the giant retinal tear group, a higher rate of ambulatory vision was achieved in the first operation anatomic success cases compared with the reoperation cases (66% vs 31%, P = 0.03). Although not statistically significant, similar outcomes occurred in the proliferative diabetic retinopathy (48% vs 25%) and proliferative vitreoretinopathy groups (54% vs 45%). Similar prognostic relationships were found for good visual acuity outcomes. CONCLUSIONS: First operation anatomic success, preoperative visual acuity, and giant retinal tear or proliferative vitreoretinopathy as the retinal detachment etiology are important factors that predict visual outcome.
