Dry Eye/OSD

Environmental factors have negative impact on ocular surface

Posted on March 11, 2021

In this single-center, prospective clinical study, 150 individuals were followed for 1 year and evaluated for non-invasive keratograph break-up time (NIKBUT), tear meniscus height (TMH), and conjunctival and limbal hyperemia. Patients also took an Ocular Surface Disease Index questionnaire.

Individuals working >4 hours at the computer had statistically significantly lower NIKBUT before work and Schirmer test results than individuals working <4 hours.

There was a statistically significantly higher conjunctival hyperemia result in individuals working >4 hours at a computer before work and after work in medical workers.

Tear film was negatively affected by low relative air humidity and air-conditioning, resulting in dry eye disease symptoms.

At the 1-year follow-up, there was a statistically significant reduction in conjunctival and limbal hyperemia in office workers. A statistically significant reduction in tear meniscus height was also noted at the first examination before and after work.
