Positions of gaze, looking down
Positions of gaze, looking down. 50-year-old man demonstrating one of the standard 'positions of gaze' while undergoing an assessment following a stroke (cerebrovascular accident). This is the 'down' gaze. Stroke, or cerebrovascular accident (CVA), is brain damage caused by the interruption of the brain's blood supply or by the leakage of blood through blood vessel walls. Strokes vary in severity with tests carried out to determine the effects of a minor stroke. This test, also used by ophthamologists, assesses a patient's ability to move the eyes in a co-ordinated fashion using the extraocular muscles and cranial nerves. The nine eye positions are up, down, left, right, up and left, down and left, up and right, down and right, and straight ahead. For a sequence showing these eye positions, see images C033/3634 to C033/3642.
