A 57-year-old woman with proliferative diabetic retinopathy in both eyes also had iris surface neovascularization with early angle neovascularization in her right eye, which regressed completely following treatment with panretinal photocoagulation. Histopathologic examination confirmed the complete absence of abnormal vessels on the iris surface or in the iridocorneal angle of the right eye; an avascular fibrous membrane persisted on a segment of the posterior iris pigment epithelium near the pupil. There was advanced rubeosis in the untreated left eye.
