We developed an automated flicker perimeter which shows a blinking target on the screen of a personal computer. The flicker sensitivity is measured at 25 points over the central 30 degree visual field. This method was applied to 49 eyes in normal persons ranging from second to 8th decade in age. The flicker sensitivity declined along with age and eccentricity. The method of limits was more rapid and induced less fatigue to the examinee than the up-and-down method. Both method gave same results. The present flicker perimetry could detect loss of sensitivity in 10 eyes out of another 24 eyes with ocular hypertension. The current setup provides a rapid and sensitive clinical test for the early detection of impaired visual function in glaucoma.
