[Quadrant cyclocryocoagulation. Initial experience]

The authors describe a modification of cycloccryocoagulation /CCC/ they used in the treatment of different types of glaucoma in a group of 320 eyes. Cryodestruction of the ciliary body was implemented with a probe at a temperature of -60 degrees C for a period of 2 x 20sec. in two points of opposite qaudrants, using a transconjunctival approach. The probe was applied at a distance of 3 mm from the limbus. Following a period of 12 months to 3 years after operation they investigated the intraocular pressure and visual acuity of the treated eyes. They recorded a hypotonic effect comparable to cryocoagulation performed by the classical procedure; the incidence of complications was lower.
