Spontaneous eye blink activity in the primary eye position and its relationship to age and gender were assessed using digital image processing techniques to quantify blink opening and closing time.
One hundred-and-eighty healthy volunteers (90 males and 90 females), divided into the age groups 0-3, 4-12, 13-20, 21-40, 41-60 and > or = 60 years old, were evaluated prospectively. They were videotaped digitally in a standard setting and the images were transferred to a personal computer (Macintosh 400) and processed with the iMovie software. Blink opening and closing time were measured at 30 frames/second. The data were then subjected to statistical analysis.
The closing time was significantly longer than the opening time for all ages and both genders. Elderly individuals (> or = 41 years old) and women had significantly longer closing times.
Image processing techniques made possible the observation of differences in spontaneous eye blink opening and closing time in relation to age and gender.
运用数字图像处理技术评估第一眼位的自发性眨眼活动及其与年龄和性别的关系，以量化眨眼的开启和闭合时间。
前瞻性评估180名健康志愿者（90名男性和90名女性），他们被分为0至3岁、4至12岁、13至20岁、21至40岁、41至60岁以及≥60岁年龄组。在标准环境下对他们进行数字录像，图像被传输至个人电脑（Macintosh 400）并用iMovie软件进行处理。以每秒30帧的速度测量眨眼的开启和闭合时间。然后对数据进行统计分析。
所有年龄组和两性的眨眼闭合时间均显著长于开启时间。老年人（≥41岁）和女性的眨眼闭合时间显著更长。
图像处理技术使得观察与年龄和性别相关的自发性眨眼开启和闭合时间差异成为可能。
