الملخص EN

An unusual case of a free-floating peripheral pigmented cyst in the anterior chamber is presented.

A 30-year-old Caucasian male presented reporting a visual defect on his right eye in prone position over the past year.

Slit-lamp examination revealed a small pigmented free-floating peripheral iris cyst at the 6 o’clock position in the anterior chamber.

Ultrasound biomicroscopy revealed an unfixed epithelial pigmented cyst with an extremely thin wall and no internal reflectivity.

Due to the lack of severity of visual disturbance of the patient, no surgical treatment was indicated.

The patient is to be followed up annually and advised to return immediately in case of pain or any visual symptoms.

Free-floating iris cysts in the anterior chamber are uncommon and remain stable in the majority of cases.

Management includes only regular observation until any complications arise.
