Abstract
AbstractThis study introduces a novel technique for estimating visual field by using overlapped fixation patterns obtained by the amounts of displacement in voluntary eye movements during searching‐tracking trials, as an alternative screening medical device for visual field examination. The proposed system was evaluated by glaucoma patients in order to study whether or not the proposed system can be used as a visual field detection device for screening. The proposed system was found to detect visual field abnormality to a certain extent. However, there were some cases in which detection of Mariotte blind spots was inaccurately performed. The experimental results revealed that there was room to reconsider our understanding regarding the effect of ptosis, overlapping with eyesight, as well as calibration of the display position to the correct location to be examined. The results of the evaluation experiment indicated that this proposed system has the potential to be used as a visual field examination device for screening. © 2012 Wiley Periodicals, Inc.
