Then, trabeculectomy with mitomycin C and pan-retinal photocoagulation(PRP) or extra-PRP were conducted within 2 d. The follow-up time was 6 mo. Best-corrected visual acuity(BCVA), intraocular pressure(IOP), neovascularization of iris(NVI) were recorded before and after treatment.RESULTS: Within 2 d 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 2 d after injection is the optimal time window for trabeculectomy, which can maximally reduce the risk of perioperative hyphema.展开更多
