A review on technology and different probes in transscleral cyclophotocoagulation

Abstract

Glaucoma is a chronic progressive optic neuropathy, characterised by retinal ganglion cell loss leading to optic nerve head changes and visual field defects. The control of intraocular pressure remains a key determinant factor in the management of glaucoma. Cyclodestructive procedures target the epithelium of ciliary processes, thereby reduces the aqueous formation. Cyclodestructive procedures have advanced from initial cyclodiathermy to micropulse diode laser cyclophotocoagulation (CPC). The various probes used in transscleral CPC (TSCPC) include G-probe delivery device and G-probe illuminate delivery device for continuous wave TSCPC and micropulse P3 probe for micropulse diode laser TSCPC. This review article provides details on design of probes and their technology.
