PURPOSE: To report an initial case series of Japanese patients with refractory glaucoma treated with endoscopic cyclophotocoagulation (ECP) using an ECP device that was equipped with a 532-nm neodymium-doped yttrium aluminium garnet (Nd:YAG) laser. METHODS: This observational case series included 10 consecutive glaucomatous eyes (7 with primary open-angle glaucoma; 3 with secondary glaucoma after cataract surgery) of 10 Japanese subjects (7 men, 3 women; mean age ± standard deviation, 65.7 ± 15.0 years) who underwent ECP to control intraocular pressure (IOP), and preserve visual function. Age, sex, glaucoma type, ocular surgical history, preoperative and postoperative logarithm of the minimum angle of resolution visual acuity (VA), IOP, number of antiglaucoma medications, perioperative complications, and treatments for complications were collected from the medical and surgical records. The IOP and numbers of antiglaucoma medications were compared between preoperative and postoperative values. RESULTS: The mean preoperative IOP (27.3 ± 5.4 mm Hg; range, 19-36) and number of antiglaucoma medications (4.4 ± 0.8; range, 3-6) decreased significantly by 53% and 39% ( p = 0.0005 and p = 0.0043, respectively) to 12.9 ± 5.2 mm Hg (range, 8-20) and 2.7 ± 1.4 (range, 0-4), respectively, at the final visit. Compared with preoperative values, a mixed-effect regression model showed significant decreases in the IOP and numbers of medications at every time point up to 24 months postoperatively. No phthisis bulbi or persistent hypotony was recorded. At the final visit, compared with preoperative values, the VA decreased in three eyes by >0.2 unit because of glaucoma progression. CONCLUSIONS: ECP with Nd:YAG laser is a reasonable option in eyes with refractory glaucoma.
