Research Abstract

Using the Octopus 1-2-3 and its remote software package, we developed a strategy for automated static flicker perimetry in the central 30゚ visual field on an IBM personal computer. The catch trials for the false-positive and the false negative answers were programmed to evaluate the cooperation of the patient. The short-term fluctuation was also tested to examine the reliability of flicker perimetry. Using this program, we studied the static flicker fusion fields of 100 normal subjects and 36 patients with early glaucoma.
The profile of the normal static flicker fusion field was found to be almost flat in shape under our examination conditions. The flicker fusion threshold decreased slightly shape under our examination conditions. The flicker fusion threshold decreased slightly with age. In most of the normal subjects, the catch trials of our automated flicker perimetry were less than 15%, indicating that the patient reliability was almost as good as that of Octopus perimetry. Automated static flicker perimetry was able to detect early glaucomatous visual field defects which had not been clearly recognized by Octopus perimetry.
