Inadvertent Cyclodialysis Cleft and Hypotony Following Ab-Interno Trabeculotomy Using the Trabectome Device Requiring Surgical Repair.

PURPOSE

To report the first case of inadvertent cyclodialysis cleft and hypotony requiring surgical repair following ab-interno trabeculotomy (AIT) using the Trabectome device, and the postoperative clinical results following direct suture cyclopexy.

METHODS

A 55-year-old man with hypotonous maculopathy secondary to cyclodialysis cleft inadvertently created 3 years earlier during AIT using the Trabectome device was referred for repair. Direct suture cyclopexy was performed and topical homatropine and dexamethasone drops were prescribed postoperatively.

RESULTS

Gonioscopic examination revealed complete cleft closure on postoperative day 1 confirmed by anterior segment optical coherence tomography. At 11 weeks postoperatively, visual acuity had improved from 20/400 to 20/40, with resolution of preoperative macular folds on fundoscopic examination. At 9 months postoperatively, visual acuity had further improved to 20/20 with intraocular pressure stable at 9 mm Hg maintained on travoprost and brimonidine.

CONCLUSIONS

Inadvertent cyclodialysis cleft from a malpositioned AIT and resultant hypotony is rare and in this case was successfully treated by direct suture cyclopexy.
