[Most recent developments in the field of optical and electronic visual aids for severely visually handicapped and blind patients].

Magnifying spectacles represent one of the indispensable optical aids (Keplerian systems having surpassed Galilean systems during the last years), closed-circuit television, Optacon, and navigating aids based on ultrasound as environmental sensors. -None of the other navigating aids have proved useful. Initial successes have, however, been achieved with a miniature hand-held camera for closed-circuit television and a portable electronic reading system (View-Scan). Genuine progress has been made with the braille information storage systems, which utilize computer technology to store texts which have been read and written, and subsequently to print them or reproduce them on a screen or in synthetic language. Braillex in the Federal Republic of Germany and Versabraille in the U.S.A. are examples of such systems. In special cases a newly developed stereo photocopy system (Minolta) will be useful for newly blinded adults. However, texts in the form of tactile copies have to be highly magnified in order to be palpable and readable.
