Transient unilateral loss of vision can be a manifestation of ipsilateral carotid disease; whereas transient visual impairment affecting both eyes simultaneously suggests vertebral basilar-artery insufficiency. We present such a case where the symptoms were related to head position. Congenital anomalies of the vertebral arteries were found on four-vessel cervical angiography.
