To develop the Crow's Feet Grading Scale for objective quantification of the severity of lateral canthal lines and to establish the reliability of this photonumeric scale for clinical research and practice.
A 5-point photonumeric rating scale was developed to objectively quantify the severity of lateral canthal lines at rest and at maximum contracture of the orbicularis oculi. Nine experts rated photographs of 35 subjects, twice, with regard to the aspect crow's feet in comparison with morphed images. Inter- and intrarater variability was assessed by computing intraclass correlation coefficients.
The agreement between the experts was significantly high. Furthermore, the test-retest correlation coefficients were high for each expert after an overnight interval, demonstrating low inter- and intraevaluator variability.
The 5-point photonumeric scale generated spans the severity of the type of crow's feet for which patients most commonly seek correction. The scale is well stratified for consistent rating.
开发鱼尾纹分级量表，用于客观量化外眦纹严重程度，并确立此数字评分量表在临床研究与实践中的可靠性。
制定了一个5分数字评分量表，以客观量化静息状态及眼轮匝肌最大收缩时外眦纹的严重程度。9名专家对35名受试者的照片进行两次评分，将鱼尾纹情况与变形图像进行比较。通过计算组内相关系数评估评分者间和评分者内的变异性。
专家之间的一致性非常高。此外，经过一夜间隔后，每位专家的重测相关系数都很高，表明评估者间和评估者内的变异性较低。
所生成的5分数字评分量表涵盖了患者最常寻求矫正的鱼尾纹类型的严重程度。该量表分层良好，便于进行一致的评分。
