Abstract
Long‐term visual results in the first 124 consecutively vitrectomized eyes of 105 diabetic patients in our department were evaluated. The indications for vitrectomy were unresorbable vitreous haemorrhage (77 eyes, 62%) (group A), central traction retinal detachment (21 eyes, 17%) (group B), and a combination of both (26 eyes, 21%) (group C). Initially visual acuity (VA) improved at least by one category in 83 eyes (67%). The latest post‐operative VA after the mean follow‐up of 3.7±0.2 years was > = 0.3 in 36 eyes (29%), 0.1‐0.25 in 15 eyes (12%), 0.05‐0.08 in 9 eyes (7%), counting fingers (CF) 1‐< 3 m in 13 eyes (11%), and < CF 1 m in 51 eyes (41%). The latest VA of 0.3 or better was significantly more common in group A (40%) than in group B (10%) or group C (12%) (P=0.0087 and 0.0076, respectively). The most common causes of visual failure (VA <C F 1 m) were neovascular glaucoma and/or retinal detachment. At the latest follow‐up visit 50% of the patients had VA of 0.3 or better, 16% were in the low‐vision category, and 34% were blind (VA < 0.05).
