Multiple bilateral primary cysts of the iris pigment epithelium.

CASE REPORT: Diagnostic and therapeutic considerations in the case of a 57-year-old man with multiple iris cysts in both eyes.

COMMENTS: Small and hidden from view, most primary iris cysts of the iris pigment epithelium remain clinically silent. Larger cysts may be noted on examination, but often remain difficult to visualize due to their location. By providing a high-resolution view of the iris and ciliary body, ultrasound biomicroscopy is a useful adjunct to the clinical examination in distinguishing primary cysts of the iris pigment epithelium from solid uveal neoplasms.
