Iris fluorescein angiography in diabetic vitrectomy patients.
Preoperative iris fluorescein angiograms (IFA) and ophthalmic records of 34 diabetic patients who underwent vitrectomy were reviewed. Of 2 patients without clinically apparent rubeosis, 23 showed evidence of iris microvascular abnormalities or rubeosis on IFA. Patients with rubeosis (Grades III and IV) on IFA had a 63% incidence of postoperative neovascular glaucoma, thus isolating them as a high risk group. The visual outcome of patients developing neovascular glaucoma was poor.
