PURPOSE: To evaluate the clinical outcome of transscleral cyclophotocoagulation (TSCPC) with the diode laser for different glaucomas, especially as primary surgery. METHODS: A retrospective analysis of 250 TSCPCs (193 eyes of 140 patients) with different glaucomas, and an average age of 62.6 ± 17.1 years. postoperative follow-up ranged from six to 48 months (mean, 13.9 months). Most patients had primary open-angle glaucoma (POAG) or secondary glaucoma. All eyes were treated with 24-30 spots and 1.4-1.8 W, at an exposure time of two seconds, using a diode laser with a focusing tip. RESULTS: The mean intraocular pressure (IOP) decreased from 14.6 ± 6.7 before to 19.3 ± 5.7 mmHg after operation (p < 0.001). IOP was successfully controlled (final IOP, 10-22 mmHg) in 76.4% of cases after a single or multiple TSCPC treatments. The reduction in maximum IOP and in the number and frequency of administration of antiglaucomatous drugs was also significant (p < 0.001). The best results were obtained in the patients with POAG, in the oldest age group, and in those patients without any previous or subsequent glaucoma operations. The proportion of eyes requiring multiple treatments was 21.2%, with an average of 1.3 treatments per eye. There was a 14.4% complication rate, mostly of mild uveitis. Phthisis bulbi occurred in three eyes (1.6%). CONCLUSIONS: TSCPC with the diode laser is a safe, effective procedure for reducing IOP in the treatment of different glaucomas, with few severe complications. It is also suitable for primary surgical treatment.
