OBJECTIVE: To determine the relative effectiveness of neodymium:YAG cyclophotocoagulation (NCYC) and pars plana modified Baerveldt implant (PPBI) surgery on intraocular pressure (IOP) control in eyes with neovascular glaucoma (NVG). PARTICIPANTS: In this retrospective comparative group study, 30 patients with NVG treated with contact NCYC were compared with 18 patients who underwent PPBI. Patients groups were not statistically dissimilar with respect to the underlying disorder-causing angle and iris neovascularization, intraocular pressure, and patient's age. RESULTS: During a follow up of 6 months, an IOP control of > or = 6 and < or = 21 mm Hg was achieved in 23 eyes (76.6%) treated with NCYC compared with 17 eyes (94.4%) receiving PPBI (P = 0.13). Among eyes that had unsuccessful outcome in both groups, the proportions with persistently high IOP or hypotony were greater in the NCYC group than in the PPBI group. Based on our criteria, the cumulative proportion of failure in the NCYC group was 23.3% at 6 months as compared to 5.6% in the PPBI group. Seven eyes (23.3%) in the NCYC group lost light perception versus 1 eye (5.6%) in the PPBI group. The incidence of postoperative choroidal effusion (36%) was higher in the PPBI group. CONCLUSIONS: This study suggests that in the management of NVG, PPBI surgery more frequently controls IOP in a medically acceptable range with less hypotony and greater preservation of visual acuity than NCYC.
