Laser Therapies: Cyclodestructive Procedures

Early attempts to reduce intraocular pressure (IOP) through treating the ciliary body utilized the process of diathermy to destroy aqueous-producing cells. This method quickly fell out of favor due to a high rate of hypotony as well as lack of efficacy. Cryotherapy was another early method of ciliary body ablation, and, while the results were more successful and repeatable than diathermy, freezing of the ciliary body never achieved widespread acceptance. The use of cyclophotocoagulation (CPC) was first reported in the early 1960s using a xenon arc photocoagulator for ciliary body destruction. A decade later, the arc photocoagulator was replaced by a laser and development of the present form of cycloablation began its evolution.
