Jan 2010 Blink

A 31-year-old Caucasian male presented with conjunctivitis in his right eye. His history was notable only for chronic floaters. Visual acuity was 20/20. Dilated examination revealed an iris cyst at 3 o'clock in his right eye. He was referred to ocular oncology at Duke Eye Center to confirm the presence of an iris cyst and rule out a possible developing mass.

When we saw him two weeks later, the patient expressed no ocular discomfort despite slit-lamp exam findings that showed homogeneous elevation of the iris and an overlying stroma that appeared stretched. The remainder of the iris was normal and the pupil was round. When dilated, a translucent cyst became visible resting against the crystalline lens without sign of a forming cataract.

The patient is currently being observed. No action will be taken unless the cyst grows to obstruct the patient's vision or grows to include peripheral angle structures.
