Abstract

Blinking plays an important role in maintaining corneal integrity by spreading of the tear film. Although there are studies reporting on blink rate and tear stability, a consensus has not been reached. Therefore, the blink rate and tear breakup time (TBUT) test were performed in 159 healthy young females. The mean TBUT and blink rate values observed were 18.9 seconds and 18.6 blinks/min, respectively. A significant correlation (r = 0.74, p < 0.05) between TBUT and blink rate was found. These results demonstrate that blink rate may be dependent on TBUT, at least among subjects with TBUT less than 19 seconds. Thus, blink rate may depend not only on cortical stimuli but also on the stability of the tear film.

摘要

眨眼通过泪膜的扩散在维持角膜完整性方面发挥着重要作用。尽管有研究报道了眨眼频率和泪膜稳定性，但尚未达成共识。因此，对159名健康年轻女性进行了眨眼频率和泪膜破裂时间（TBUT）测试。观察到的平均TBUT和眨眼频率值分别为18.9秒和18.6次/分钟。发现TBUT与眨眼频率之间存在显著相关性（r = 0.74，p < 0.05）。这些结果表明，眨眼频率可能取决于TBUT，至少在TBUT小于19秒的受试者中如此。因此，眨眼频率可能不仅取决于皮层刺激，还取决于泪膜的稳定性。
