Rapid improvement of retinal and iris neovascularization after a single intravitreal bevacizumab injection in a patient with central retinal vein occlusion and neovascular glaucoma

Background Intravitreal injections of bevacizumab have been reported to have anatomical and functional success in treating choroidal neovascularization, macular edema and neovascular glaucoma. We report a case with neovascular glaucoma due to central retinal vein occlusion who demonstrates rapid resolution of anterior and posterior segment neovascularization after a single intravitreal bevacizumab injection. Case A 46-year old man with a 6-month history of central retinal vein occlusion presented with neovascular glaucoma. Fluorescein angiography revealed marked leakage from new vessels on the iris, disc and retina. Bevacizumab was used after incomplete panretinal photocoagulation because of inadequate fundus visualization. About a week after intravitreal bevacizumab injection, new vessels were no longer visible. IOP improved and additional laser photocoagulation was performed. Conclusion Intravitreal bevacizumab injection may be a useful alternative or adjuvant treatment for patients with neovascular glaucoma in whom inadequate visualization precludes adequate panretinal photocoagulation.
