Ultrasound Biomicroscopy - Guided Surgical Intervention for Cyclodialysis Clefts

O cular hypotony is associated with significant visual dysfunction depending on its severity and duration. One etiology of hypotony is cyclodialysis cleft (CDC), a disinsertion of the longitudinal ciliary muscle fibers from the scleral spur. Originally described as a planned surgical treatment for intractable glaucoma, CDC may be observed following trauma or as an inadvertent surgical event from a variety of procedures involving iris or angle manipulation such as goniotomy, trabeculectomy, phacoemulsification, intraor extra-capsular cataract extraction, iridectomy, and sclerotomy. It can also be present in cases of anterior proliferative vitreoretinopathy (PVR) with traction on the ciliary body causing an occult CDC.1
