BACKGROUND AND AIMS: The main purpose of our work is to create a reliable, free and open-source software for visual field diagnosis, which is mainly designed for the use with personal computers. Our goal is argued by the fact, that professional clinical equipment used for the visual field estimation is very expensive and mostly occur only in specialized medical centers. This, in turn, affects its availability, giving rise to a problem not only for patients requiring frequent and regular testing of the visual field, but also for those, who would like to examine their sight purely preventive. METHODS: To date, the initial version of the application called Specvis was established. It has been satisfactorily tested so far in a brief study on sample of 20 healthy volunteers, where half of them had simulated deficits of the left visual field. The group with „deficits” used specially prepared glasses with covered left and partially right eye, where in contrast „control” group had covered only left eye. Experimental procedure consisted of responding to stimuli appearing in different parts of the screen with simultaneous monitoring of fixation by responding to changes of the centrally located fixation point. RESULTS: The use of specially prepared glasses resulted in the observation of deficits in the left part of visual field in the „deficits” group. Statistical analyzes revealed the existence of differences between both groups in the left part of the visual field. CONCLUSIONS:The brief validation study had shown, that Specvis has the potential worth developing further. Actually our software is being validated in clinical conditions with automated perimetry in the study of visual field deficits of glaucomatous patients. It is worth mentioning, that thanksto wide configuration settings of the stimulus characteristics Specvis is also useful in animal studies. Our work is supported by ERA-NET Neuron grant REVIS.
