SUBJECTIVE EVALUATION OF THE DEGREE OF SEVERITY OF DRY EYE SYNDROME ACCORDING TO THE OSDI QUESTIONNAIRE AMONG PEOPLE WITH SIGNS OF COMPUTER VISION SYNDROME

The most common and pronounced manifestation of computer vision syndrome (CVS) is dry eye syndrome (DES), the incidence of which, according to various authors, varies from 11.6% to 61.0%. At the same time, information about the possibilities of using on-line technologies for qualitative and quantitative assessment of the nature and severity of the formation of CVS in general, and DES in particular, is clearly insufficient.
Based on this, the purpose of this study was to assess the possibility of using the author’s multidimensional scale in on-line mode to determine the nature and severity of DES in users of video display terminal (VDT).
Material and methods. 585 people (average age 21.6±0.1 years) were surveyed online using a multidimensional author's questionnaire and the Ocular Surface Disease Index (OSDI, Ocular Surface Disease Index). Results: Symptoms of CVS were detected in 87.4% (n=511) of respondents, respectively, in 12.6% of students (n=74) no symptoms of visual discomfort were detected, while ocular surface disorders were found in 28.4% of those examined with signs of CVS. The most common complaints were blurred vision - 53% of respondents, increased sensitivity to light - 48.9%, pain in the eye - 44.4%. No significant correlations were found between experience, duration of use of devices and the condition of the ocular surface according to OSDI. A tendency to some deterioration in OSDI performance was found when the device screen is located above eye level.
Conclusions. The results obtained are consistent with the data of other authors and confirm the relevance and effectiveness of using a multidimensional scale to study the nature and severity of manifestations of CVS and DES for on-line screening ophthalmological studies.
