To introduce a novel adjuvant technique to locate cyclodialysis cleft using a laser pointer in a gonioscopic view.

A 36-year-old man complaining of blurred vision in his left eye after blunt trauma 2 weeks prior was referred to our hospital. Gonioscopy showed a cyclodialysis cleft from 3 to 4 o’clock and fundus revealed hypotonic maculopathy. After the failure of medical treatment, we tried various interventions such as injection of viscoelastic agent into the anterior chamber and intravitreal gas tamponade with transconjunctival cryotherapy. Since those were not successful, we decided to treat the patient with direct cyclopexy. For the preoperative localization of the cleft, we tried a new technique that uses a laser pointer. On gonio-scopic examination, an assistant shot the laser toward the limbal area where the suspicious cleft was located. We were able to precisely locate the cyclodialysis cleft if the laser pointer light was seen through the cleft in the gonioscopic view. With the aid of a laser a pointer, the cleft was successfully closed.

Localization with a laser pointer is simple, safe, rapid, and helpful for planning surgical repair of a cyclodialysis cleft without expensive equipment.
