USING PERSONAL COMPUTERS AT SCREENINGS OF VISUAL FUNCTIONS

Background The number of medical screenings is increasing. This fact i s specially pronounced in the field of occupational health. Due to res tricted financial resources and limitations in time there is a need fo r rationalisation in medical screenings. Material and Methods Possible uses of personal computers (PC) enabling organisational and financial benefits in medical screenings are suggested. By means of a test for colour-blindness it is shown how unfavourable technical conditions may be by-passed. Results and discussion Rationalisation in medical scree nings can be achieved when using the PC as a multi-functional screenin g-device as well as an expert system, measuring apparatus and as a com munication-device. Due to a lack of literature it is difficult to disc uss possible effects of technical differences between PC-based screeni ngs of visual functions and screenings where ''traditional''. Reliabil ity, sensitivity and validity is insufficiently investigated for many of the commercial available screening-devices based on a PC.
