Abstract
- PURPOSE
Iris cyst is a rare condition and there has been no Korean report of bilateral iris cyst. The authors present the first Korean report of a patient with bilateral iris cysts. METHODS: A 62-year-old man presented with intermittent visual field disturbance of the left eye when exposed to bright light. The patient underwent visual field examination and slit lamp examination. On slit lamp examination, a dark-brown mass was revealed along the lateral pupillary margin in the left eye. In the right eye, the shape of the iris was convex at the 8 o'clock direction. Ultrasound biomicroscopy, confirmed the presence of a mass. RESULTS: The patient showed no specific abnormality in visual field examination. Ultrasound biomicroscopy showed the objects to be cystic, with a thin-walled homogenous hypoechoic lesion on the posterior surface of the iris in both eyes. There were two cysts in each eye measuring 4.35 mm x 1.13 mm and 1.47 mm x 1.11 mm in the left eye, and 1.05 mm x 1.02 mm and 1.90 mm x 1.05 mm in the right eye. CONCLUSIONS: Asymptomatic iris cyst does not need to undergo treatment, but careful examination is nevertheless required required at regular intervals in case a complication develops.
