The lost of eye movement has long been known as a symptom of schizophrenia.
Schizophrenic individuals showed difficulty in tracking slow-moving objects smoothly with their eyes. They also have difficulty in maintaining a steady gaze.
Dr. Philip Benson and Professor David St Clair developed the combination of eye tests including smooth pursuit test, the free viewing test (involving everyday scenes) and the fixation task test. Their research is published in the November issue of the academic journal Biological Psychiatry.
