RESUMO
PURPOSE: To describe a case series of neovascular glaucoma (NVG) caused by central retinal vein occlusion (CRVO) that was treated with intravitreal bevacizumab (IVB; Avastin). DESIGN: Retrospective interventional case series. METHODS: Six consecutive patients with NVG and a refractory, symptomatic elevation of intraocular pressure (IOP) and pronounced anterior segment congestion received IVB (1.25 mg/0.05 ml). Diode laser cyclophotocoagulation was carried out only if pressure was controlled insufficiently by topical medication. Follow-up examinations occurred at four to 16 weeks. RESULTS: IVB resulted in a marked regression of anterior segment neovascularization and relief of symptoms within 48 hours. IOP decreased substantially in three eyes; in the other three eyes, adjuvant cyclophotocoagulation was necessary. No side effects were observed. Panretinal photocoagulation (PRP) was performed as soon as feasible, five to 12 weeks after IVB treatment. CONCLUSION: IVB leads to a rapid regression of iris and angle neovascularization and should be investigated more thoroughly as an adjunct in the management of NVG.
