Cyclophotocoagulation with an illuminated laser probe under a noncontact wide-angle retinoscope: A modified technique of ciliary body photocoagulation.

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.
