A case of traumatic cyclodialysis followed by ultrasound biomicroscopy.

We report a case of persistent traumatic cyclodialysis treated by goniophotocoagulation and observed by ultrasound biomicroscopy (UBM) throughout the course. A 16 year-old male was struck in his right eye by a rocket firework. After the injury, hypotony continued for 4 months and he was referred to Hiroshima University Hospital. At that time, the best visual acuity in his right eye was 0.2 and the intraocular pressure was 6 mmHg. Three hundred and sixty degrees of cyclodialysis, partial peripheral anterior synechia, hypotony maculopathy and subretinal proliferative tissue were observed. Cyclodialysis was obvious by UBM. From 4 months after the injury goniophotocoagulation was performed six times in 2 months. Intraocular pressure recovered 6 months after the injury and reattachment of cyclodialysis and disappearance of the suprachoroidal space were confirmed by UBM. UBM was useful in observing cyclodialysis throughout the course.
