    Stromal Iris Cyst

    A 50-year-old Asian man was referred to our clinic for a baseline evaluation of an iris lesion in his left eye. The patient stated that the lesion was noted on a routine eye exam two years previously and that he has no recollection of its being present before that time.

    The patient had no relevant medical history and was not on any medications. His visual acuity was 20/20, and intraocular pressure was 12 mmHg. The cornea was clear, the chamber was quiet and deep, and there was a trace of nuclear sclerotic cataract. The iris lesion extended from the 4 to 6 o’clock positions and could be transilluminated.

    An ultrasound biomicroscopy was performed, which confirmed the presence of a cystic iris mass with no solid component. He was diagnosed with a stromal iris cyst. Two follow-up examinations determined that there was no growth and that the situation remained stable.
