AI Summary
Vitrectomy for diabetic vitreous hemorrhage often improves vision (78%), but iris neovascularization and lens removal during surgery predict worse outcomes, guiding patient selection and prognosis.
Abstract
The surgical results for 248 eyes that underwent vitrectomy for diabetic vitreous hemorrhage showed that at the final examinations, 194 (78%) had improved visual acuities, 43 (17%) had worse visual acuities, and 11 (4%) were unchanged. Of the 248 eyes, 60 (24%) had final visual acuities of 20/40 or better, 128 eyes (52%) had final visual acuities of 20/50 to 20/800, and 60 (24%) had final visual acuities worse than 20/800. Eyes with preoperative iris neovascularization had a substantially worse visual result than eyes without this complication. Eyes in which the lenses were removed during vitrectomy also had worse visual results, primarily because they had a higher cumulative incidence of postoperative iris neovascularization and neovascular glaucoma.
