It has been hypothesized that small amounts of myopia may be due, in some degree, to ciliary spasm. This thesis proposed that a significant amount of low myopia can be reduced with only a small amount of auditory biofeedback training. A total of 10 subjects in two groups, one control and the other experimental, each underwent a total of 18 thirty second biofeedback trials in six sessions over a 10 day period. Although we found what appeared to be a small amount of myopia reduction Ln the experimental group, it was not significantly different from that found in the control group. Thus we conclude that a significant reduction, due to auditory biofeedback training, cannot be obtained with so few training sessions.
