Effectiveness of optometric vision therapy

One hundred consecutive optometric vision therapy patients' records were evaluated to determine what changes occurred in the visual processing system. An ordinal visual performance scale was utilized to rate visual functioning on a one hundred point scale. The scale divides the visual processing system into 10 functions of 10 points each. Each of the 10 functions improved at the .001 level of significance as a consequence of the binocular vision therapy treatment program.
