Spontaneous Closure of Cyclodialysis Cleft in a Case of Normal-Tension Glaucoma Post Ab-Interno Trabeculotomy
Huang MY; Tseng HYCureus 2022; 14: e23276
A cyclodialysis cleft (CDC) is the detachment of longitudinal ciliary muscle from scleral spur, causing an unusual communication between anterior chamber and suprachoroidal space, resulting in possible hypotony. We report a case of a 63-year-old woman with normal-tension glaucoma (NTG), who developed a shallow anterior chamber with relatively low intraocular pressure (IOP, 6-8 mmHg) after combined ab-interno trabeculotomy and phacoemulsification. Her vision reached good (20/20) with the mild myopic shift. After detecting subtle signs of clinical hypotony, CDC was confirmed and monitored using anterior segment optical coherence tomography. Five months after surgery, she encountered an episode of eye pain, with transient IOP elevation and deepening of the anterior chamber. Spontaneous closure of CDC was suspected and confirmed gonioscopically. To the best of our knowledge, this is the first case to describe the clinical course of spontaneous CDC closure in a patient with NTG after ab-interno trabeculotomy. It is advisable to inform the patient about potential IOP spike after spontaneous closure once CDC is diagnosed.
