Visual rehabilitation programs typically require a wide selection of source materials capable of being rapidly accessed and, as required, conveniently interchanged. Computer technology has facilitated the creation, storage and access of data, in both text and graphic image form. Consistent with this, computer technology has the potential to provide an efficient medium for visual rehabilitation programs. A computer program has been developed to assist in training persons with central field loss to eccentrically view. The program has four components: a module to establish the eccentric viewing point at an appropriate angle and degree of eccentricity; an exercise module to reinforce the chosen eccentric viewing position; a module to encourage the application of eccentric viewing technique to visual tasks other than reading including exercises for clients unable to appreciate print material; a module comprising advanced reading material to extend reading skills for appropriate persons. Initial clinical trials indicate that this computer program provides a successful method of teaching eccentric viewing technique.
