Brief Summary:

Background: One of the most difficult refractory glaucomas in treatment is the neovascular type and its association with dense cataract add to this difficulty. This study aimed to provide results of triple surgical treatment of such conditions.

Methods: A total of 12 eyes of 12 patients with dense cataractus NVG patients were included in this study. The patients mean age was 57.25 ± 5.9 years. The mean pre-operative intraocular pressure (IOP) was 47.25 ± 4.04 mmHg with maximum antiglaucoma therapy. The mean best corrected distant visual acuities (BCDVA) in log MAR was 2.13 ± 0.38. All the patients received intra-vitreal injection of 1.25 mg (0.05 ml) bevacizumab followed by phacoemulsification, pars plana vitrectomy (PPV) including pan-retinal photocoagulation (PRP), and assisted trabeculectomy with Mitomycin c (MMC). Mean IOP and BCDVA changes were the main outcome results of this study.
