PURPOSE
To accurately assess eyelid and eyebrow position, we have developed a new measurement method using a digital image analysis system.
MATERIALS AND METHODS
(1) Plotting the corneal limbus by transferring to the software digital images of the patient's eyes in the primary gaze position; (2) determining the corneal ring, center, and longitudinal diameter; and (3) measuring the upper eyelid and eyebrow position. The method was tested on 24 patients with senile blepharoptosis and 45 young healthy eyelids without ptosis.
RESULTS
The upper eyelid position of patients with blepharoptosis was significantly lower, and their eyebrow position is significantly higher than those of healthy subjects. The upper eyelid and eyebrow position of the patients with blepharoptosis corelated, but no correlation was observed in the healthy subjects.
CONCLUSION
Our measuring system is a simpler, easier, and more accurate way of measuring both upper eyelid and eyebrow position than are currently used techniques.
目的
为了准确评估眼睑和眉毛的位置，我们开发了一种使用数字图像分析系统的新测量方法。
材料与方法
（1）将患者在第一眼位时眼睛的数字图像传输到软件中，绘制角膜缘；（2）确定角膜环、中心和纵向直径；（3）测量上睑和眉毛的位置。该方法在24例老年性上睑下垂患者和45例无睑下垂的年轻健康眼睑上进行了测试。
结果
上睑下垂患者的上睑位置明显较低，眉毛位置明显高于健康受试者。上睑下垂患者的上睑和眉毛位置相关，但健康受试者中未观察到相关性。
结论
我们的测量系统是一种比目前使用的技术更简单、更容易、更准确地测量上睑和眉毛位置的方法。
