A specific questionnaire was applied to them on the exposure time and the type of visual display terminal (VDT) used, as well as the computer vision symptoms scale (CVSS17). DED was diagnosed with the Ocular Surface Disease Index (OSDI). Ocular surface damage and signs of DED were evaluated with the tear rupture time test (TBUT), the integrity of the ocular surface by ocular surface staining (OSS) and the production of the aqueous basal tear film using the Schirmer test.Results: Average computer exposure time, measured differently, was positively correlated with DED development. The computer exposure time measured in hours per year and TBUT showed a significant negative correlation (p < 0.001) (rho − 0.463). Years of computer exposure and staining of the ocular surface showed a significant positive correlation (p < 0 0.001; rho 0.404). The accumulated exposure time was negatively correlated with TBUT (p < 0.001; rho − 0.376) and positively with OSS (p < 0.001; rho 0.433). Schirmer test did not correlate with computer exposure time.Conclusion: The prolonged time of exposure to the computer in subjects with CVS was significantly correlated with the DED tests, in the different ways of measuring it; but not with the Schirmer test.Keywords: computer vision syndrome, dry eye disease.Sánchez-Valerio MRMohamed-Noriega KZamora-Ginez IBaez Duarte BGVallejo-Ruiz VDove Medical Pressarticlevisual display terminal (vdt)computer vision syndrome (cvs)dry eye disease (ded)tbut (tear break-up time)ocular surface staining (oss)schirmer test. h/d: hours per dayd/w: days per weeky/ce: years of computer exposureh/w: hours per weekh/y: hours per yearch/ty: cumulative hours in total years of computer exposure at workOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 4311-4317 (2020)
