Purpose: This study aimed to investigate the efficacy of cyclophotocoagulation with an illuminated laser probe under a noncontact wide-angle retinoscope in treating refractory glaucoma. Methods: Eleven patients (11 eyes) with refractory neovascular glaucoma were treated with ciliary body photocoagulation. Preoperative and postoperative corrected visual acuity, intraocular pressure (IOP), ophthalmofundoscopy, B-ultrasound and ultrasound biomicroscopy, optical coherence tomography, and fundus fluorescein angiography were performed. Results: Preoperative IOP ranged from 45 to 58 mmHg (mean 51.9 mmHg). At postoperative 1, 3, and 6 months, the IOPs ranged between 16 and 33 mmHg (mean 27.1 mmHg), 14–28 mmHg (mean 20.6 mmHg), and 14–28 mmHg (mean 18.5 mmHg), respectively. IOP at the last follow-up (range 7–12 months) was 15–24 mmHg (mean 18.8 mmHg). An average of 63.8% decrease in postoperative IOP was found in these patients with no associated complications. The postoperative fibrotic exudate, anterior chamber hyphema, and exudative choroidal detachment were all well-managed and resolved. No patients experienced intraocular lens deviation or dislocation, hypotonia oculi, atrophy of eyeball, retinal detachment, endophthalmitis, or sympathetic ophthalmia. Conclusion: Cyclophotocoagulation with an illuminated laser probe under a noncontact wide-angle retinoscope is a safe and effective technique for the treatment of neovascular glaucoma.
