Intraocular temperatures were investigated during cryosurgery of the ciliary body in albino rabbit eyes. A significant temperature differential was noted between the temperature of the cryosurgical probe and the temperature within the involved tissue. Attempts were made to relate temperature changes in the ciliary body of these rabbit eyes to the clinical course following cryosurgery for the treatment of glaucoma. The need for −80 C as the optimum operating temperature is further emphasized, and the drastic changes following freezing with lower temperatures are illustrated.
