The purpose of this study was to evaluate the accuracy of stereophotogrammetric area measurements in the periocular region and analyze the differences between the 2 genders and 2 races.
A prospective study was performed on healthy young volunteers. The sample was composed of 20 Caucasians and 20 Chinese volunteers. Five objects of different sizes (0.16 cm, 0.36 cm, 0.64 cm, 1.44 cm, and 2.56 cm) were placed at 7 periocular locations. Caliper and the VECTRA M3 system were used for direct and 3D stereophotogrammetric analysis. Accuracy and differences in 2 different genders and 2 races were analyzed. The predictor variable was the mean absolute deviation between the 2 measurement methods. The nonparametric Wilcoxon signed-rank test or paired t-test was used to test the statistical differences between the 2 measurement methods. A P value < .05 was considered statistically significant.
The mean difference between the 2 measurements of all objects was less than 0.02 cm, nonparametric Wilcoxon signed-rank test or paired t-test showed no statistically significant (P > .05, respectively) differences between the 2 measurement methods, except for object 1 and object 5 (endocanthion). Chinese and female volunteers tend to have lower accuracy than Caucasians and male volunteers.
Three-dimensional stereophotogrammetry is highly accurate for area measurements in the periocular region.
本研究旨在评估立体摄影测量法测量眼周区域面积的准确性，并分析两种性别和两个种族之间的差异。
对健康年轻志愿者进行了一项前瞻性研究。样本由20名白种人和20名中国志愿者组成。将五个不同大小（0.16厘米、0.36厘米、0.64厘米、1.44厘米和2.56厘米）的物体放置在7个眼周位置。使用卡尺和VECTRA M3系统进行直接测量和三维立体摄影测量分析。分析了两种不同性别和两个种族之间的准确性和差异。预测变量是两种测量方法之间的平均绝对偏差。使用非参数Wilcoxon符号秩检验或配对t检验来检验两种测量方法之间的统计学差异。P值<0.05被认为具有统计学意义。
所有物体两次测量的平均差异小于0.02厘米，非参数Wilcoxon符号秩检验或配对t检验显示，除了物体1和物体5（内眦）外，两种测量方法之间没有统计学显著差异（P值分别>0.05）。中国志愿者和女性志愿者的准确性往往低于白种人和男性志愿者。
三维立体摄影测量法在眼周区域面积测量方面具有很高的准确性。
