title: Ciliochoroidal effusion with persistent hypotony after trabectome surgery.
abstract: The trabectome is a novel form of ab interno trabeculectomy that ablates and remove the trabecular meshwork and the inner wall of Schlemm's canal and subsequently expose the natural drainage pathway (the collector channels) to aqueous humor. Complications associated with the trabectome are few and among them is transient hypotony. We report a case of a prolonged ciliochoroidal effusion with hypotony after ab interno trabeculectomy using the trabectome with cyclodialysis cleft detected by 80 MHz ultrasound biomicroscopy in a previously neither nonoperated nor traumatized eye. Transient hypotony has been reported after the trabectome surgery. Very few cases were associated with inadvertent intraoperative cyclodialysis, but there are no cases of prolonged hypotony with ciliochoroidal effusion with cyclodialysis. In our case, associated transient intraoperative and postoperative hypotony with a history of chronically high pressure along with the possible contribution of low-grade postoperative inflammation may have precipitated the ciliochoroidal effusion with prolonged hypotony associated with cyclodialysis.
