Purpose To report long‐term results and estimate long‐term prognostic factors for visual acuity following modern diabetic vitrectomy. Methods Retrospective review of patient files from a large diabetes center between 1996 and 2010. Surgical history was obtained from the Danish National Patient Register. Follow‐up intervals were 3 months and 1, 3, 5 and 10 years after surgery. Results In total, 167 patients had diabetic vitrectomy. Surgery indications were non‐clearing vitreous hemorrhage (47%) or tractional retinal detachment (53%). Median visual acuity increased from 0.06 before surgery to 0.21 after surgery (p<0.001) and stabilized. The proportion of patients with reading ability stabilized as from the 3‐month follow‐up. After 10 years, 66% of the operated eyes were pseudophakic or aphakic and 13% carried silicone oil. Preoperative iris rubeosis was correlated with inability to read after 1 and 3 years (p<0.04). Use of silicone oil was correlated with inability to read at all follow‐up examinations (p<0.05). Conclusion After diabetic vitrectomy, visual acuity improved and stabilized as from the 3‐month follow‐up. The most consistent long‐term predictor of unfavorable visual acuity was use of silicone oil as tamponade agent. The results can be used to counsel patients on the risk of complications after surgery.
