[Trans-scleral cyclo-photocoagulation. Results over 6 months]

Transscleral contact cyclophotocoagulation with ND YAG Laser continuous mode permits the induction of a focused ciliary process with a secretory surface decrease. This treatment has been used for the treatment of refractory glaucoma since 1987. We report the treatment by transscleral cyclophotocoagulation of 49 patients with terminal glaucoma. All 49 patients had a measurable visual acuity and an elevated intraocular pressure under maximal medical treatment. None could be operated by trabeculectomy. The origin of the glaucoma was neovascular (26 patients), open angle glaucoma (9 patients) secondary glaucoma (14 patients). 62.2% of the patients had an intraocular pressure < or = 25 mm after 6 months; 8% showed decrease visual acuity. We describe the complications of the treatment and compare the efficacy of treatment depending on the origin of the glaucoma: neovascular or not.
