BACKGROUND Neovascular glaucoma (NVG) is a type of secondary angle-closure glaucoma that can result from severe retinal ischemia, such as proliferative diabetic retinopathy. Vascular endothelial growth factor (VEGF) plays a role in ocular neovascularization, which can result in NVG. The use of bevacizumab, an anti-VEGF antibody, has been shown to lead to the rapid resolution of ocular neovascularization and may be used off-label in conjunction with panretinal photocoagulation in the treatment of neovascular glaucoma. CASE REPORT A 71-year-old man presented with neovascular glaucoma in both eyes secondary to proliferative diabetic retinopathy and was treated with both panretinal photocoagulation and an intravitreal injection of bevacizumab, which led to the rapid resolution of his iris neovascularization. A follow-up examination after 12 months showed that there was no recurrence of neovascularization. CONCLUSION This case shows the possible beneficial effects of bevacizumab in conjunction with panretinal photocoagulation as a treatment option for neovascular glaucoma.
