Neovascular glaucoma (NVG) resulting from ischemic insults caused by various diseases, such as proliferative diabetic retinopathy and central vein occlusion, remains a challenging situation. This case report aims to describe the complex management of NVG, resulting from diabetic retinopathy, to achieve the best visual outcome. A 47-year-old male presented with poor visual acuity of both eyes. His right eye was inoperable. Ahmed valve implantation with intraoperative intravitreal bevacizumab injection was performed in his left eye. Panretinal photocoagulation was performed serially after phacoemulsification. However, intraocular pressure was found to be raised, thus necessitating 5-fluorouracil needling bleb revision and administration of intracameral bevacizumab injection. During 15 months of follow-up we were able to achieve the best visual outcome possible in this patient. Comprehensive management of NVG should be implemented with a multidisciplinary approach.
