Purpose:To report the technique of pneumatic cyclocryopexy for the repair of traumatic cyclodialysis clefts. Methods:Traumatic cyclodialysis clefts were repaired in 2 phakic eyes and one aphakic eye of 3 patients. Clefts were localized with gonioscopy and ultrasound biomicroscopy (UBM). External cryotherapy was applied over the cleft in a confluent fashion. An intravitreal perfluoropropane gas bubble (C3F8, 0.3 cc) was then injected and the patient was positioned to tamponade the cleft. Results:Follow-up ranged from 2 months to 1 year. Preoperative visual acuities ranged from 20/100 to 2/200 and improved to 20/25 to 20/30 following pneumatic cyclocryopexy. Intraocular pressure increased from 2 - 5 mmHg preoperatively to 15 - 18 mmHg at the last follow-up. One patient required temporary treatment with topical drops to control intraocular pressure. Fundus exam demonstrated resolution of hypotonous maculopathy in all cases. Gonioscopy and/or UBM demonstrated closure of the clefts. There were no complications. Conclusion:Pneumatic cyclocryopexy is a simple, safe, and effective approach to the management of traumatic cyclodialysis clefts.
