Abstract:Background: Dry eye disease (DED) is one of the most frequently established diagnosis in ophthalmology. Dry eye is heterogeneous, multifactorial disease characterized by loss of homeostasis of the tear film accompanied by combination of ocular symptoms in which tear film instability and hyperosmolarity, ocular surface inflammation, damage and neurosensory abnormalities play etiological role. The two main categories of DED are evaporative dry eye and aqueous deficient dry eye.
Aims and Objectives: To study the effect of screen time on dry eye disease indicators, corneal endothelium and morphology of Meibomian gland
Materials and Methods: A prospective observational study conducted for One year with total 80 number of patients with inclusion criteria Patient aged 18-60 years of either sex with History of visual display terminal with division in two groups (Group A:->6 hours per day & Group B:- <2 hours) with certain exclusion criterias as systemic disease, trauma etc. Data like name, age, sex, Schirmer’s test, Tear film breakup time (TBUT), Ocular Surface Disease Index (OSDI), corneal endothelium and Meibomian gland morphology would be recorded.
Result: My study stated that Positive association of screen time on dry eye disease indicators with significant Deviation from the normal morphology of meibomian gland was observed more in group A as compared to group B with Corneal endothelial cell density in both Group A and Group B were within normal limit.
Conclusion: Average screen exposure time is positively correlated with significant deviation in morphology of meibomian gland such as atrophy and screen induced dry eye disease mainly through impaired blinking patterns which Changes in parasympathetic signalling.
