چکیده
|
Purpose. to compare the effect of airflow exposure on the tear meniscus and blink frequency in normal and evaporative dry eye subjects. methods. in 9 normal subjects and 9 short tear breakup time (sbut) dry eye subjects,lower tear meniscus height (tmh) and area (tma) and blink frequency were measured with anterior segment optical coherence tomography (oct) before and after 5 minutes of airflow exposure (1.5±0.5 m/s). results. in sbut dry eyes,both tmh and tma decreased significantly (p=0.027,p=0.027) with a significant increase of blink frequency after airflow exposure,while significant increase in tma was found in normal eyes. conclusion. measurement of the tear meniscus with anterior segment oct seems to be useful as a noninvasive and objective method for evaluating the effect of airflow on tear film. © 2012 shizuka koh et al.
