Relationship between the Use of Video Terminals and Dry Eye Symptoms during the COVID-19 Pandemic: Assessments Based on a Meta-Analytical Approach

Abstract

Purpose: The objective of this meta-analytical study is to consider the impact of the use of VDTs on the onset and/or worsening of the signs and symptoms of dry eye during the COVID-19 pandemic, but also to offer the best solutions to perform the various tasks in daily life in order to safeguard vision, with the aim of promoting a lifestyle that allows you to work and perform different activities more safely and efficiently. Patients should be encouraged to follow proper planning of visits. Methods: Scientific articles chosen by the following inclusion criteria were analyzed: 1) Type of study (Primary); 2) Population (patients suffering from dry eye); 3) Study period (all studies carried out in the period between January 2020 and January 2022); 4) Result variables (correlation between increased use of VDTs during the pandemic and worsening of the symptoms of dry eye syndrome; correlation between autoimmune mechanism from Covid- 19 and etiology of dry eye); 5) Language (English). Results: The results of the various cross-sectional studies, obtained thanks to the administration of an online and anonymous questionnaire, have found a correlation between excessive use of VDTs and the onset of complications related to dry eye syndrome. The results suggest that in university students there is a higher incidence of problems related to dry eyes following the many hours spent in front of a screen to follow the lessons that were proposed to them remotely during the lockdown following the COVID-19 pandemic. Dry eye is the most commonly diagnosed pathology among eye disorders during the lockdown, as people spent much more time locked in the house, even 20-24h in the first months of lockdown in 2020. Conclusions: In conclusion, the analysis of the data shows a correlation between prolonged use of VDTs (exacerbated during the COVID-19 era) and the onset or worsening of dry eye syndrome.
