Meibomian Gland Dysfunction Causing Dry Eye Syndrome in Computer Users

Abstract

Background: Meibomian glands are follicular glands that release lipid that shapes the tear film's superficial layer. A persistent, extensive terminal duct blockage and descriptive alterations in the secretory output indicate meibomian gland dysfunction. Digital eye strain is characterized by changes in ocular surface integrity, tear film function, blinking patterns, accommodation disorders, differences in fixation, dryness, weariness and discomfort while using digital gadgets. The COVID 19 pandemic have resulted in almost everything to be on digital platform. Objective: To conclude after reviewing various studies (between Jan 2016- Dec 2020) which were focused on how digital eye strain adversely affects the function of meibomian glands and adds to symptoms of dry eye in computer users. Study Design: Narrative review article Methodology: Various articles were reviewed which got published in between 2014-2020 in indexed journals. Meibomian gland dysfunction significantly affects the factors such as blink rate, tear break-up time (TBUT), tear evaporation rate, tear film composition as well as corneal staining, we will find its significant effect and relation to digital eye strain. Expected Results: Based on previous articles. Results: Digital eye strain significantly affects the function of meibomian gland, thus results in altered and poor tear film that finally results in dryness of eyes. Conclusion: Eyes with meibomian gland dysfunction, develop changes such as, reduced blink rate, shorter tear breakup time; altered tear film composition and disturbed ocular surface which adds on to symptoms of dry eye especially in chronic computer users.
