The paper discusses development of visual test software that is used in mobile telemedicine screening complex (MTSC). It is a set of medical devices controlled by a portable computer and means of wirelessly transmitting data to the analysis centre. This complex is used for screening purposes to detect potential problems in the patient’s health. Altogether screening complex has 14 measurement modules that measure the status of 12 body subsystems. This paper addresses the development of one of these modules – a visual test. Vision test software consists of two parts – visual acuity test and colour test. Visual acuity test is done using a computer screen for displaying test symbols and using remote control for patient response input. Colour vision test is carried out similarly by displaying pictures of coloured numbers on coloured background and requiring a patient to input those numbers using a keyboard or a mouse. The paper focuses on the development of methodology and implementation of both visual tests.
