Description
Summary:Purpose: To assess effect of prolonged digital screen exposure on ocular surface. Methodolgys: In this prospective cohort study, patients were enrolled on the basis of history of prolonged digital exposure (>2hrs/day). Dry eye evaluation was done by Schirmer's with anesthesia, Fluorescein-Tear film Break-up Time (F-BUT) and corneal and conjunctival fluorescein staining. Patients were categorized as per our severity based grading based on objective tests. Results: Twenty six patients (52 eyes) of mean age 27.76 +/-5.16 years (range 17 to 41 years) were selected for the study. Headache and redness were the most common symptoms (22.22% each). F-BUT was found to be less than 5 seconds in 92.3% of patients. Ocular surface staining was present in 75% of the patients. Schirmer's came to be the most unreliable factor (>10 mm). Majority (71.15%) of the patients were having moderate grade of digital strain, as per our severity grading. Exposure duration was not found to be correlating with objective tests. Conclusion: Routine dry eye objective tests are affected in patients with prolonged digital screens exposure. There is no defined minimum duration of exposure that will have adverse effects on ocular surface. New grading system may serve as common guideline for the treatment of digital strain in future.
