BACKGROUND: To describe the utility of ultrasound biomicroscopy in diagnosing multiple bilateral iridociliary cysts and to determine the clinical significance of this condition. METHODS: A retrospective review of 73 patients referred for ultrasound biomicroscopy who were found to have bilateral iridociliary cysts. RESULTS: Seventy-three patients were identified who demonstrated 2 or more cysts in 1 eye and at least 1 in the other with ultrasound biomicroscopy. A solitary iris elevation was the most common reason for referral (84.9%). There were 44 patients for whom sufficient follow-up data were available, with a mean follow-up of 40.4 months. Clinical sequelae included 1 case of sectoral cataract (2.3%) and 4 cases of cyst-related glaucoma (9.1%). INTERPRETATION: Multiple bilateral iridociliary cysts is a common condition with occasional clinical significance. Ultrasound biomicroscopy is a valuable technique in diagnosing this condition. Patients who have significant angle compromise should be followed and treated as required for glaucoma.
