The importance of studying the pathogenesis of computer vision syndrome (CVS) is due to the ever-increasing number of users of digital information technologies (DITs) and visual dis-play devices (VDDs) who work with them for long periods of the day. Most studies have classi-cally focused on epidemiological and etiological aspects of CVS. This article analyses 9 national and 42 international studies on CVS with a focus on its pathogenesis. The pathophysiological aspects of dry eye syndrome and accommodative dysfunction as the main branches of CVS in DIT and VDD users are discussed in the light of the morphological and functional unity of visual functions. The role of psychological status in the development and progression of refractive errors due to abnormalities in serotonin and dopamine metabolism is emphasized. Classical and recently published data on the possible role of sensory and visual-motor integration of the two main visual analyzer information channels (dorsal and ventral) in the development of CVS are discussed. A hypothesis based on the literature data and the results of our own research on the disintegration of visual and visual-motor processes in the development of CVS as a result of excessive, uncontrolled use of VDDs is hypothesized based on published data and the author's results.
Keywords: computer vision syndrome, dry eye disease, accommodation, pathogenesis, neurophysiology, visual motor integration.
