Vitreous hemorrhage secondary to iridociliary cyst

An 18-year-old man, presented a lower vitreous hemorrhage of unknown cause. Multiple tests are performed, including Ophthalmic Ultrasound and Fluorescein Angioghaphy (FA), they did not find justification of bleeding. Finally, we decide to do a Biomocroscopía Ultrasonic (UBM) showing an iridociliary cyst.

The iridociliary cysts are single or multiple, primary or secondary. The primaries are usually benign so, they do not require treatment. When the cyst has a considerable size, it may produce a focal plateau iris with or without angle-closure. Our case reveals an unusual complication that should take notice of when you have an unknown vitreous hemorrhage.
