  • Abstract
  • Look Inside

Microcomputer is utilized to evaluated the con-trast sensitivity function (c.s.f.) with T.V. display.The contrast of the grating pattern and spatial fre-quency is automatically changed and with auto-matic data processing, the results is displayed in an instance.

With this system, no examiner is required skillful technique, it simply works with the examinee's use of two push buttons. This means, we can exclude the unnecessary factors due to examiner's anticipa-tions and/or leading questions. Right after the test, we can make or give necessary dicision and treat-ment to the patients without delay.
