To evaluate the effects of the intravitreal (IV) injection of bevacizumab on anterior segment neovascularization using anterior segment angiography. Methods: We observed 1 eye with iris and iridocorneal angle neovascularization and 3 with neovascular glaucoma from 4 patients with diabetic retinopathy in 3 eyes and central retinal vein occlusion in 1 eye. Two healthy eyes from 2 other patients served as control eyes. Three eyes, including 1 normal eye, were examined by iris angiography; the other eyes underwent iridocorneal angle angiography with fluorescein (FA) and indocyanine green (IA) using a Heidelberg Retina Angiograph 2. After angiography, 4 eyes with neovascularization were treated with IV bevacizumab (1.25 mg per 0.05 mL) and underwent angiography once more 4 to 6 days after treatment. Results: Iris angiography with indocyanine green revealed many iris vessels, but not dye leaking, in both normal and glaucomatous eyes, and the angiography with
The activity of CNV was reduced after PPV in eyes with age-related macular degeneration with vitreous hemorrhage. Visual acuity significantly improved, with only rare severe complications. The involvement of vitreomacular traction in the patho-physiology of CNV in age-related macular degeneration is possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
