A Case of Traumatic Cyclodialysis Cleft Diagnosed by Ultrasound Biomicroscopy

ABSTRACT

Cyclodiaysis is a disinsertion of the longitudinal muscle of ciliary body from its attachment to the sclera at the scleral spur, allowing direct communication between the anterior chamber and ciliochoroidal space. Although the diagnosis can usually be confirmed by gonioscopy, sometimes it may be difficult to detect the cleft in recently traumatized or operated eyes because of corneal edema, hyphema, or very shallow anterior chamber with hypotony. The authors experienced a case of traumatic cyclodialysis cleft which was difficult to detect due to shallow anterior chamber and hypotony. We diagnosed it easily using ultrasound biomicroscopy and treated it successfully by direct cyclopexy. Ultrasound biomicroscopy is a noninvasive method that can accurately diagnose the presence of traumatic cyclodialysis and can aid in surgical management. It is particularly useful in the presence of hazy media, hypotony, and/or abnormal anterior segment anatomy.
