Although most visually handicapped pateints can be adequately rehabilitated visually through the prescription of low vision optical aids, some who have very poor vision and who need to do a great deal of reading may be helped through the prescription of a closed-circuit television reading system. It was found that six of 17 patients tested with such a system could benefit from it. The system used includes a push-button operated scanning device (described in the article) for shifting the image on the page.
