The aim of this article is to validate the accuracy of Facial Assessment by Computer Evaluation (FACE) program in eyelid measurements. Sixteen subjects between the ages of 27 and 65 were included with IRB approval. Clinical measurements of upper eyelid margin reflex distance (MRD1) and inter-palpebral fissure (IPF) were obtained. Photographs were then taken with a digital single lens reflex camera with built-in pop-up flash (dSLR-pop) and a dSLR with lens-mounted ring flash (dSLR-ring) with the cameras upright, rotated 90, 180, and 270 degrees. The images were analyzed using both the FACE and ImageJ software to measure MRD1 and IPF.Thirty-two eyes of sixteen subjects were included. Comparison of clinical measurement of MRD1 and IPF with FACE measurements of photos in upright position showed no statistically significant differences for dSLR-pop (MRD1: p = 0.0912, IPF: p = 0.334) and for dSLR-ring (MRD1: p = 0.105, IPF: p = 0.538). One-to-one comparison of MRD1 and IPF measurements in four positions obtained with FACE versus ImageJ for dSLR-pop showed moderate to substantial agreement for MRD1 (intraclass correlation coefficient = 0.534 upright, 0.731 in 90 degree rotation, 0.627 in 180 degree rotation, 0.477 in 270 degree rotation) and substantial to excellent agreement in IPF (ICC = 0.740, 0.859, 0.849, 0.805). In photos taken with dSLR-ring, there was excellent agreement of all MRD1 (ICC = 0.916, 0.932, 0.845, 0.812) and IPF (ICC = 0.937, 0.938, 0.917, 0.888) values. The FACE program is a valid method for measuring margin reflex distance and inter-palpebral fissure.
本文旨在验证计算机评估面部测量（FACE）程序在眼睑测量中的准确性。经机构审查委员会（IRB）批准，纳入了16名年龄在27至65岁之间的受试者。获得了上睑缘反射距离（MRD1）和睑裂（IPF）的临床测量值。然后使用带有内置弹出式闪光灯的数码单反相机（dSLR-pop）和带有镜头安装环形闪光灯的数码单反相机（dSLR-ring）拍摄照片，相机分别处于直立、旋转90度、180度和270度的位置。使用FACE和ImageJ软件分析图像，以测量MRD1和IPF。纳入了16名受试者的32只眼睛。将MRD1和IPF的临床测量值与直立位置照片的FACE测量值进行比较，结果显示，对于dSLR-pop相机，差异无统计学意义（MRD1：p = 0.0912，IPF：p = 0.334）；对于dSLR-ring相机，差异也无统计学意义（MRD1：p = 0.105，IPF：p = 0.538）。对于dSLR-pop相机，在四个位置上用FACE与ImageJ获得的MRD1和IPF测量值进行一对一比较，结果显示MRD1具有中度至高度一致性（组内相关系数：直立时为0.534，旋转90度时为0.731，旋转180度时为0.627，旋转270度时为0.477），IPF具有高度至极佳一致性（ICC = 0.740、0.859、0.849、0.805）。在使用dSLR-ring相机拍摄的照片中，所有MRD1（ICC = 0.916、0.932、0.845、0.812）和IPF（ICC = 0.937、0.938、0.917、0.888）值均具有极佳一致性。FACE程序是测量睑缘反射距离和睑裂的有效方法。
