To report a case of a cyclodialysis cleft that was successfully managed with gonioscopically guided transscleral cyclopexy using partial-thickness scleral flap.

A 44-year-old man complaining of blurred vision in the left eye after blunt trauma was referred to our hospital. The intraocular pressure (IOP) was 4 mmHg and the visual acuity was counting finger. Gonioscopy examination revealed cyclodialysis cleft from 3 to 6 o'clock and fundus examination revealed macular folds. After the failure of conservative medical therapy and laser photocoagulation, gonioscopically guided transscleral cyclopexy using partial-thickness scleral flap was performed. Four months later, the IOP was 18 mmHg, the visual acuity was 0.8, and fundus examination showed the disappearance of the macular folds.

Transscleral cyclopexy using partial-thickness scleral flap is a safe and effective method to treat hypotony maculopathy due to cyclodialysis and to minimize pupil distortion.
