PURPOSE: To evaluate the effect of intra-silicone injection of bevacizumab for the treatment of neovascular glaucoma (NVG) after vitrectomy for advanced proliferative diabetic retinopathy. METHODS: Bevacizumab was injected into the silicone oil in five pseudophakic eyes of five patients with NVG. The iris neovascularization (INV) and NVG had developed 1.5-4 months after vitrectomy and silicone oil tamponade. The main outcome measures were regression of INV, intraocular pressure and visual acuity. RESULTS: In all eyes, INV regressed and intraocular pressure was controlled within 7 days. Visual acuity improved in all eyes. In one patient, INV and NVG recurred 10 weeks after the injection and was successfully treated with a repeat intra-silicone bevacizumab injection. CONCLUSION: Intra-silicone injection of bevacizumab is effective in the treatment of patients with INV and NVG after vitrectomy for advanced proliferative diabetic retinopathy.
