Add Tag | Summary: | The advance of Information and Communication Technologies (ICT) during the last decade has motivated the use of new electronic devices worldwide to satisfy work, social and academic requires, and others; which prolonged use predisposes to possible effects on visual health. This research purpose was to determine Dry Eye Syndrome (SOS) by relating a diagnostic test (tear breakup time (TBUT)) with exposure time to electronic screens in users who were attended at "Vision Care" ophthalmologic center. The study was descriptive, prospective, cross-sectional, performed on 60 people (19 men and 41 women); whom tear breakup time was evaluated. Dry Eye Syndrome was considerable in the female gender with a 68% frequency; the age group between 40 and 49 years was the one with the highest prevalence of SOS; and there is a significant negative correlation between TBUT and the hours of exposure to electronic screens (Pearson correlation -0. 70), with the following interpretation: the longer exposure time to a screen, the faster the tear precipitates because of instability or its early evaporation, resulting in a reduced tear breakup time (<10 seconds). Key words: tear breakup, tear film, flicker, hyperosmolarity. |
