PURPOSE: To describe the clinical characteristics of eyes with secondary angle-closure glaucoma following combined phacovitrectomy. METHODS: Retrospective case series. RESULTS: Nine eyes developed angle-closure glaucoma due to iris posterior synechiae with an incidence rate of 1.82% (95% CI: 0.64 - 3%) among 493 eyes following phacovitrectomy. PDR with TRD was the most common surgical indication. Single piece IOL insertion and silicone oil were present in all cases. Fibrin in the anterior chamber was found in six eyes postoperatively. Mean degree of iris bombe was 310±79.37° at 3.55±1.87 weeks with a mean IOP of 32.56±5.89 mm of Hg. Systemic diabetes and grade of cataract were the only significant risk factors (r2 =1; p= 0.016 and 0.049, respectively). Nd:YAG laser PI relieved the angle-closure attack in all cases. CONCLUSION: Systemic diabetes and advanced grade of cataract are significant risk factors for secondary angle-closure glaucoma following combined phacovitrectomy.
