Diode laser cyclophotocoagulation (DLCPC) is a new cyclodestructive procedure for the treatment of refractory, advanced glaucoma. Information about the effectivity of this procedure is still lacking. First results of a prospective study are presented.
Methods: Fifty-four eyes of 54 patients with advanced, refractory glaucoma were consecutively treated with DLCPC. The patients were followed for one year after first treatment. Successful treatment was defined as 1. a decrease of IOP to 5-21 mmHg in eyes with a visual acuity of 1/50 or more; 2. a decrease of IOP < 30mmHg in eyes with a visual acuity of less than 1/50 (including blind eyes) or relief of pain.
Results: A follow-up of one year was achieved in 51 of 54 eyes. Forteen eyes had inflammatory glaucoma, 9 open angle glaucoma, 9 neovascular glaucoma, 8 traumatic glaucoma, and 11 other types of glaucoma. Before DLCPC, 31 eyes had been treated with other surgical procedures for glaucoma, and 31 eyes had other surgical procedures (pseudophakia n=15, aphakia n=13). DLCPC was successful in 37 eyes (72,5%). Twenty-eight eyes (55 %) required one or more repeat treatments. Within the follow-up, another surgical procedure was performed in 7 eyes (13,7%) to control IOP. No serious side effects occured.
Conclusions: This study suggests that DLCPC is an effective, safe method in the treatment of advanced glaucoma. In comparison to cyclocryocoagulation, DLCPC is associated with fewer side effects.
