Computer vision syndrome from the standpoint of principles of diagnostics and treatment of accommodative and sensory visual fatigue: literature review

The review was performed using databases Russian Science Citation Index and PubMed, with the search keywords being "computer vision syndrome", "accommodation", "quality of life", "visual performance", "critical fusion and flicker frequency", "contrast sensitivity". The sources were selected in accordance with the criteria of prospective or retrospective studies. The data obtained indicate that the problem of diagnosis and treatment of accommodative and sensory visual fatigue in patients with computer vision syndrome is relevant in modern conditions of industrial activity due to the high frequency of distribution and possible negative impact on labor productivity. By now, the literature has formulated the basic principles of diagnostics and treatment of accommodative visual fatigue associated with the use of objective (accommodography) and subjective (quality of life) research methods, as well as the use of specific treatment methods (exposure to low-energy laser radiation, magnetophoresis, hardware optical-reflex training) taking into account a differentiated approach to the type of asthenopia. Much less developed is the problem of sensory visual fatigue, based on diagnostics using special research methods (critical frequency of fusion and flickering, contrast sensitivity at low spatial frequencies) and the implementation of therapeutic and restorative measures taking into account the syndrome-pathogenetic approach to the use of physical methods of treatment, one of which (in the long term) is ophthalmochromotherapy.
