Abstract
We have already developed an eye movement analyzing system using an infrared ray television fundus camera. Though the quality of the eye fundus TV images is not good, the system can measure the eye movement with an accuracy of 0.08 degree. We tried to apply this system to compensating the eye movement in making the retinal sensitivity map. Target mark with variable brightness is presented to various positions of the retina of a subject through a CRT assembled in the infrared ray TV fundus camera. The subject is supposed to respond if he can perceive the target mark. The TV image of the eye fundus with overlayed target mark and response sign is recorded into the U-matic VTR. Then the image of the video tape is analyzed by a computer. We have obtained the retinal sensitivity maps, which show good agreement with the results of Goldmann perimeter.
