Abstract | BACKGROUND: Long-term outcome and complications of diode laser cyclophotocoagulation ( DCPC) may be important, since eyes, once treated with DCPC, are less likely to be subjected to other types of interventions in the further follow-up. METHODS: Retrospective review of 131 eyes of 127 patients treated from 2000 through 2004. Success was defined as intraocular pressure (IOP) at last visit 6-21 mm Hg; hypotony: IOP </=5 mm Hg. RESULTS: Mean follow-up (FU) was 30.1 (SD 16.7) months. Mean number of treatment sessions per eye was 1.54, 89% of the eyes having 1 or 2 sessions; overall re-treatment rate: 38.9%. Mean total laser energy delivered per eye: 133.9 (73.7) J; mean energy per treatment episode: 86.8 (22.0) J. Eyes with 3 or more treatments (11%) had a significantly larger proportion of post-traumatic glaucoma, and patients were significantly younger. All eyes had refractory glaucomas on maximal medication, neovascular glaucoma (NVG) representing the largest subgroup (61%). IOP decreased from 36.9 (10.7) mm Hg pretreatment to 15.3 (10.4) mm Hg at the end of FU. Success was noted in 69.5% (91 eyes), failure (non-response) in 13%. Hypotony occurred in 17.6% eyes, of which 74% had NVG. Hypotony developed after mean 19.3 (11.0) months, range 6 to 36; with 96% of these eyes having received only 1 or 2 treatments; delivered energy did not differ from that in the successful eyes. CONCLUSIONS:
DCPC is an efficient treatment for refractory glaucoma. Hypotony, the most common complication, may develop as late as 36 months post-treatment. Diagnostic category and age seem to influence the outcome stronger than laser protocol and delivered energy.
