MICROFLUCTUATIONS OF ACCOMMODATION COEFFICIENT WHEN USING SMARTPHONES (RESULTS OF PRELIMINARY STUDIES)

Abstract

Computer visual syndrome (CVS) is found in 32-90% of digital devices users. In most studies, the etiological and pathogenetic factors of accommodative asthenopia in CVS are discussed from the point of view of physiological optics, but the mechanisms of nervous regulation of accommodation in the formation of CVS are missed.Purpose. Preliminary assessment of the possibility of recording and analysis of accommodative microfluctuations as a neuroophthalmological indicator of asthenopia when using devices.Material and methods. 8 people (average age 24.1±0.6 years) were surveyed using the CVS-Q questionnaire after ophthalmological examination, as well as accommodation on a Righton Speedy-K autorefractometer before, during and after visual activity ona smartphone.Results. 7 of 8 examined according to questionnaires revealed signs of CVS; indicators of accommodation in all were in the range of unbalanced accommodation response.Conclusions. When studying the microfluctuations of accommodation during the usual smartphone visual activity, there is a tendency to a deterioration in the indices of objective accommodation, which is consistent with the survey data. Further neurooph-thalmological studies of the mechanisms of the CVS formation with the involvement of modern hardware and diagnostic tools arean actual medical and social problem.
