Ultrasound biomicroscopic findings in a case of cyclodialysis

Ultrasound biomicroscopy (UBM) with a high frequency can be used to evaluate the structure of the anterior eye segment in vivo. A 24-year-old male was referred to us after 1 month of follow-up by a local ophthalmologist, because of decreased visual acuity and hypotony after a blunt eye injury. A cyclodialysis cleft in the 2- to 4-o'clock position and a cavernous pattern all over the choroid were found using UBM. The patient underwent surgical treatment to close the cleft. Even after the recovery of intraocular pressure (IOP), the peripheral ciliary body around 360 degrees was still separated from the sclera when examined by UBM. Despite the detached ciliary body, keeping IOP within normal levels is an interesting finding. UBM is helpful in the diagnosis and treatment of traumatic cyclodialysis.
