[Are prism glasses a sensible measure in treatment of dyslexia?]

A short summary of the characteristics of speaking, reading and writing is given, followed by the respective anatomical, physiological and neuropsychological counterparts, which are to be described as the "Hör-Denk-Sprech-Seh-Schreib-Organismus" (H-D-S-S-SCH-O). Various disorders occurring in the H-D-S-S-SCH-O as well as health problems and psychological and/or sociological factors may negatively contribute to the ability of speaking, reading and writing. In each case medical and non-medical specialists should thoroughly assess the cause of the problem in order to select the most effective treatment method. An agreement was made between Dr. Pestalozzi (Olten) and the author, to asses logopedically from 1987 until 1990 at the Speech Therapy Clinic (Abteilung Klinische Logopädie, ORL-Klinik, Universitätsspital Zürich) 20 dyslexic children, aged 7 to 13 years, designated by Dr. Pestalozzi to the wearing of prism-glasses in order to cure their dyslexias. The results of this logopedic study are described and discussed.
