We developed a new flicker perimetry by presenting a blinking target on the screen of a personal computer.Flicker sensitivity was measured at 25 points within the central 30°visual field (method of limits) and at 59 points within the central 60°field (bracketing method). The test subjects included 26 normal eyes, 106 eyes with ocular hypertension,and 24 eyes with glaucoma. The method of limits took an average of 5 minutes and the bracketing method 6.5 minutes.The latter had the advantage of stable fixation and lesser fatigue even for subjects of advanced age. Some eyes with ocular hypertension showed no abnormal sensitivity for automated perimetry but decreased sensitivity for flicker perimetry.Eyes with glaucoma showed almost no frequency-dependent characteristics in decreased flicker sensitivity.
