Use Of Stereo Fly Compared To Randot Stereogram On A Normal Population.

The traditionally used clinical method for determining a patients stereo acuity over the past several years has been the Titmus Stereo Fly Test. Some concerns over the dependability and reliability of this test have been expressed by several researches because this test contains lateral displacement clues which might allow a patient to score higher than his actual stereo threshold. A similarly administered test has been developed which tries to overcome this problem in the form of the Randot Stereo Test. This paper will briefly examine the mechanics of these two tests and attempt to compare the results from the two tests on a series of normal clinical patients.
