Visual Retraining (VIDEO) University of Rochester Medical Center This video is under embargo. Please login to access this video. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Caption The video shows the visual test that helped participants improve their vision after stroke. A group of about 100 small dots appears within a circle on the screen, in the patient's blind field. The dots twinkle into existence, appear to move as a group either to the left or the right, then disappear after about one-half second. The patient has to choose whether the dots are moving left or right. A chime indicates whether he or she chose correctly. A new test appears every few seconds.
