Vitrectomy for diabetic rhegmatogenous retinal detachment.

The surgical results for 107 eyes that underwent vitrectomy for diabetic rhegmatogenous retinal detachment showed that the rhegmatogenous component of the detachment was successfully treated in 79 eyes (74%), although in 11 of the 79 eyes (14%) traction detachment of the macula persisted. At the final examinations, 57 eyes (53%) had improved visual acuities, 44 (41%) had worse visual acuities, and six (6%) were unchanged. Eleven eyes (10%) had final visual acuities of 20/40 or better, 48 eyes (45%) had final visual acuities of 20/50 to 20/800, and 48 eyes (45%) had final visual acuities worse than 20/800. Two preoperative factors were associated with a worse prognosis for achieving a final visual acuity of 20/800 or better: preoperative iris neovascularization (P less than .01) and preoperative detachment of the macula (P less than .05).
