PURPOSE: To evaluate the efficacy of contact diode laser transscleral cyclophotocoagulation using different treatment parameters. METHODS: All eyes undergoing contact diode laser transscleral cyclophotocoagulation between April 1991 and September 1997 at two institutions were enrolled. Success was defined as an intraocular pressure (IOP) less than or equal to 22 mmHg, or absence of pain for poorly sighted and blind eyes. RESULTS: Two hundred and six eyes of 204 patients (Salzburg, 117 eyes; New York, 89 eyes) were enrolled. Mean patient age was 65.8 ± 18.7 years (range, 4-96 years). Mean follow-up was 9.2 ± 11.2 months (range, 3-56 months). Mean pre- and postoperative IOPs were 42.1 ± 11.0 mmHg (range, 24-76 mmHg) and 17.3 ± 10.9 mmHg (p < 0.001) and 20.3 ± 13.2 mmHg (p < 0.001) at 12 and 24 months, respectively. The number of laser applications (mean, 186. ± 4.2; range, 10-40) and maximum laser power (mean, 2352 ± 408.5 mW; range, 1500-3000) were not associated with a lower postoperative IOP. An IOP of less than or equal to 22 mmHg was achieved in 72.7% of eyes at the mean follow-up of nine months. Thirty-three (16.0%) eyes required at least one retreatment. Phthisis occurred in four (1.9%) eyes. CONCLUSION: Contact diode laser transscleral cyclophotocoagulation is useful in eyes with refractory glaucoma in which the risks of outflow surgery are deemed unacceptable.
