Method and apparatus for the diagnosis of glaucoma and other visual disorders

摘要

A subject ( 12 ) observes an image on a display ( 10 ). A control ( 18 ) produces a fixation image at a selected position in the display, followed by a stimulus spaced from the fixation image. An eye position sensor ( 14 ) detects a saccade movement towards the stimulus. The stimulus is then replaced with a fixation image and the cycle repeated. The time taken to saccade plus the intensity of the stimulus are used to produce a retinal map of field of vision, or to assess other characteristics of the subject.
