视频终端干眼病因及眼部病理生理学改变的研究进展

Advances in Pathogeny and Pathophysiological Changes of Dry Eye Caused by Visual Display Terminal

视频终端干眼是由于长时间在视频终端前操作和注视显示屏而出现的眼部不适的一类疾病。随着电子产品应用,视频终端干眼发病率升高,对视频终端干眼发病机制也越来越重视。视频终端干眼主要致病因素有视频终端操作时间、视频终端操作期间眨眼模式以及视频终端操作者眼表暴露等,除此之外,眼部本身基础疾病或全身疾病也会引起视频终端干眼疾病。同时,视频终端干眼患者眼部会出现病理生理学改变,主要表现为眼部组织变化以及泪液中细胞因子表达改变等症状。

Dry eye caused by visual display terminal is a kind of eye discomfort caused by long-term operation in front of the visual display terminal and watching the display screen.With the application of electronic products,the incidence of dry eye has increased,more and more attention has been paid to the pathogenesis.Current studies suggest that the main pathogenic factors of dry eye from video terminal are operation time of video terminal,blink mode during operation and eye surface exposure of the video terminal operator,etc.In addition,basic diseases of the eye itself or systemic diseases can also cause dry eye from video terminals.At the same time,pathophysiological changes in the eyes will appear in the patients with dry eyes from video terminals,mainly manifested by changes in eye tissue and expression of cytokines in tear.
