title: Idiopathic pigmented free-floating posterior vitreous cyst.
abstract: A 28-year-old female who complained of visual symptoms in the right eye was admitted to the ophthalmology clinic. She had been suffering from visual disturbance for about 5 years and her symptoms had become worse during the last 2 months. There was no previous history of trauma, infection or inflammatory disorders. A pigmented vitreous cyst was detected in her ophthalmologic examination. As the patient refused, laser cystotomy could not be performed. The pigmented vitreous cyst was possibly congenital in origin and described as a cystic choristoma from the primitive hyaloid system in the literature. The movements of the cyst, causing only transient blurring of vision, may rarely affect the visual axis. The visual acuity was 20/20 in the affected eye so it was suggested that she should be followed-up periodically for her cyst.
