PURPOSE: To evaluate the efficacy of combination pars plana vitrectomy, endoscopic peripheral panretinal photocoagulation, and endocyclophotocoagulation (ECP) as compared with standard care in patients with neovascular glaucoma. METHODS: This age-matched case-controlled retrospective series of 54 eyes compared the clinical outcomes between a consecutive series of combination pars plana vitrectomy/panretinal photocoagulation/ECP (n = 27) versus the current standard of care (n = 27) for patients with neovascular glaucoma. "Standard" treatments for patients with neovascular glaucoma include panretinal photocoagulation, intravitreal bevacizumab, filtration surgery, pars plana vitrectomy, and Ahmed valve placement. RESULTS: After 1 year, mean intraocular pressure reduced from 40.7 ± 12.40 mmHg preoperatively to 12.3 ± 4.84 mmHg (P < 0.001) in the ECP group and from 34.7 ± 12.38 mmHg to 23.2 ± 12.34 mmHg in the control group (P = 0.002). Compared with controls, the mean drop in intraocular pressure in the ECP group was significantly greater at all postoperative visits. Logarithm of the minimal angle of resolution visual acuity outcomes were similar in both groups. There were 2 cases (7.4%) of postoperative phthisis bulbi in each group. CONCLUSION: Endoscopic pars plana vitrectomy, panretinal photocoagulation, and ECP seem to control intraocular pressure to a greater extent than standard glaucoma treatments in patients with neovascular glaucoma. In this aged-matched comparative case series, there was no significant difference between the two treatments' effects on visual acuity.
