Purpose: Most visually impaired patients primary want to improve their reading abilities. But furthermore, daily they have to deal with a variety of other tasks for which a minimum visual performance is necessary.
Method: In our low vision center, seventeen tasks of daily living (e.g. reading watch, pour water and recognizing coins etc.) were tested following the Melbourne Low Vision ADL Index. The importance of the respective tasks were graded by the patients on a scale from 0 to 4 (totally unimportant = 0; very important = 4). Simultaneously, the instructor judged the performance of the visual tasks on a grading scale from 0 to 4 (very unsatisfactory = 0, very satisfactory = 4). In the study 50 patients (34 women, 16 men) with an average age of 74,6 years were included. In 70% the diagnosis were macular degeneration and diabetic retinopathy. The average visual acuity was 0,18 / 0,13 (far distance) and 0,17 / 0,14 (near distance).
Results: As judged by the patients most important activities were recognizing medication, reading letters, recognizing coins, reading newspapers and recognizing headlines. As unimportant were graded: reading watch and telephone books, recognize faces and colors. As judged by the investigator the best effort were made by the patients in reading
