Latanoprost was thus found to significantly reduce IOP over 24 hours, whereas it does not affect OPP and BP in NTG patients. Therefore, it may be a useful medication for NTG.
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
Based on the observation that the VFD occupied the two temporal quadrants with no step, an NFLD with corresponding VFD associated with a classic temporal ODP, although not considered to be related to glaucoma, can progress.
: Neovascular glaucoma is a serious complication associated with retinal ischemic changes, which increase the production of vascular endothelial growth factor. Vascular endothelial growth factor has been implicated as a key molecule in the development of newly formed vessels and neovascular glaucoma. Intravitreal injection of bevacizumab, a full-length humanized anti-vascular endothelial growth factor monoclonal antibody, leads to a dramatic regression of the new iris and iridocorneal angle vessels on slitlamp examination. However, anterior segment angiography reveals that bevacizumab does not cause a regression of the neovascular vessels themselves but reduces vascular permeability while newly formed vessels are still present in the iris and iridocorneal angle. This review focuses on the pathology and diagnosis of neovascula glaucoma and the effect of intravitreal bevacizumab on the iris and iridocorneal angle neovascularization.
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.
