Comparison of encirclage and cryotherapy with argon laser in the management of traumatic cyclodialysis cleft

The study compared anatomical and functional outcome of a novel technique of encirclage and cryotherapy with the conventional argon laser in the management of traumatic cyclodialysis cleft in 19 patients (10: encirclage and 9: argon laser). The postoperative anatomical success was taken as rise in intraocular pressure (IOP) more than 6 mm Hg or the closure of cleft on gonioscopy or ultrasound biomicroscopy (UBM). Visual outcome was measured as change in logMAR visual acuity. Traumatic cataract and hypotony were present in majority. IOP>6 mm Hg was noted in 90% of encirclage group and in 77.70% of argon laser group. Two cases had non-closure of cleft. Encirclage is comparable to argon laser in terms of anatomical and functional success with possible advantage of single procedure and use in cases with failed laser.
