Cryosurgery for the Treatment of Advanced Chronic Simple Glaucoma

The surgical treatment of canine glaucoma

“…(Vogt, 1930;Stallard, 1965;Magrane, 1971), although Fremming (1960 has claimed considerable success in the dog using a modification of the technique. Cyclocryotherapy involves freezing the ciliary body in part, and is based on the same principle: its use in man has not met with general support (Bietti, 1950;Boles-Carenini & Orzalesi, 1968;De Roeth, 1968;Hilsdorf, 1970;Misium, 1970;Bellows & Grant, 1973), and whilst other techniques offer greater chances of success its use in the dog cannot be advocated at this stage. Uberreiter (1959) advocated the technique of cyclodialysis for the effective control of glaucoma in the dog, and Gelatt & Ladds (1971) preferred this technique to others in the specific treatment of angle closure glaucoma.…”

Diode Laser Cyclophotocoagulation

“…Severe congenital glaucoma with multiple failed surgeries. 6. Postpenetrating keratoplasty glaucoma.…”

“…Previously it has been carried out by various methods like surgical excision of ciliary body, 1 cyclodiathermy, 2,3 cycloirradiation, 4 cycloelectrolysis, 5 cyclocryotherapy, [6][7][8][9] ultrasound, 10 microwave cyclodestruction, 11 and currently by cyclophotocoagulation. Laser cyclophotocoagulation has now become the principal method of cyclodestrive procedures.…”

Ergebnisse der Zyklokryokoagulation bei Glaucoma chronicum mit engem Kammerwinkel

“…Dieser Eingriff wurde bisher vor allem als ultima ratio bei schwer beherrschbaren Glaukomformen, wie dem neovaskulären Glaukom, angewandt. Beirn Glaucoma chronicum im fortgeschrittenen Stadium oder fere absolutuni benchtete de Roetth (1968) uber eine Druckregulierung der operierten Augen bis zu 90%. Beim neovaskulären Glaukom liegt die Erfolgsrate allerdings wesentlich niedriger, zwischen 30 his 74% (Feibel, 1972;Faulborn, 1973;Bellows, 1973;Palimeris, 1976;Krupin, 1978).…”
