Objective: To determine the efficacy and safety of a titrated cyclocryopexy in advanced glaucomatous eyes in term of intraocular pressure control and complications. Material and Methods: Retrospective Cohort analysis of a titrated cyclocryopexy in 30 eyes of 25 patients with uncontrolled glaucoma during July 1996 to July 2003 at Hayatabad Medical Complex, Peshawar. Inclusion criteria applied was; patients having uncontrolled IOP with maximum medical therapy, previous trabeculectomy and a minimum follow-up of 2 years. All patients were assessed for glaucoma. Numbers of cryoapplications were determined according to the IOP. Four to 12 applications in one sitting were used. Repeat cryoapplication were applied at least after six-weeks of previous therapy if IOP was not controlled. Results: A total of 30 eyes of 25 patients were studied. IOP control of less than 21 mm Hg was achieved in 83% of the eyes. Mean IOP was reduced from 29 ± 4.96 pre-op to 17 ± 7.36 at two years follow-up. Forty percent of the eyes ne eded single session, 40% received 2 sessions and other 20% needed sessions. All the patients lost at least one line of Snellen chart at 2 years follow-up, 70% retained useful vision, 20% retained light perception and 10% lost perception of light. Serious complications included phthisis, persistent vitreous hemorrhage with retinal detachment, and total retinal detachment and persistent vitreous hemorrhage in 1 eye each. Conclusion: Cyclocryopexy appears to be an effective procedure in cases of advanced glaucoma with an acceptable risk / benefit ratio. If done in a titrated manner the number of complications are reduced in severity.
