AIM: To evaluate the effect of intracameral injection of conbercept for the treatment of advanced neovascular glaucoma (NVG) after vitrectomy with silicone oil tamponade. METHODS: Conbercept 0.5 mg/0.05 mL was injected into the anterior chamber of 5 eyes, which had developed advanced NVG after vitrectomy with silicone oil tamponade. Then, trabeculectomy with mitomycin C and pan-retinal photocoagulation (PRP) or extra-PRP were conducted within 2d. The follow-up time was 6mo. Best-corrected visual acuity (BCVA), intraocular pressure (IOP), neovascularization of iris (NVI) were recorded before and after treatment. RESULTS: Within 2d after injection, IOP control, and NVI regression were optimal for trabeculectomy. Hyphema occurred in one eye in the process of injection. But none of them present hyphema after trabeculectomy. At the end of follow-up time, all eyes had improved BCVA, well-controlled IOP, and completely regressed NVI. CONCLUSION: Intracameral injection of conbercept is safe and effective in the treatment of patients with advanced NVG after vitrectomy with silicone oil tamponade. Within 2d after injection is the optimal time window for trabeculectomy, which can maximally reduce the risk of perioperative hyphema.
