Iris microhemangiomatosis is an unusual, benign vascular abnormality that can cause spontaneous and recurrent hyphema with transient vision loss. Active bleeding is rarely documented and usually presumed, based retrospectively on nontraumatic layered hyphema. We report a case of iris microhemangiomatosis with videographically documented active bleeding.
