A custom biofeedback computer program for strabismus using the Apple IIGS and Visigraph Eye Monitoring System was evaluated. Two strabismic subjects underwent training sessions using the program and the Visigraph Eye Monitoring System. Numerous difficulties were found including: premature program tennination, computer "freezes", lag in tone produced compared to eye movements, and patient motivational factors. The lack of future availability of the Visigraph Eye Monitoring System also hinders the value of the program. The program demonstrated great customizability along with the ability to produce hardcopy information about training session data. The program was also found to be extremely easy to use. The relative usefulness of the program increases the benefit of further modifying and/or rewriting the program for a more powerful computer.
