Eyelid morphology is highly susceptible to aging. Previous studies have described the process of eyelid aging in Caucasians; however, anthropometric data describing aging in Chinese eyelids are lacking. Therefore, this study aimed to quantitatively analyze the effect of aging on the eyelids of Chinese women through a three-dimensional (3D) anthropometry.
In this prospective, cross-sectional study, 3D photos were captured from 188 healthy Chinese Han women, who were categorized into four age groups. Anthropometric landmarks were identified for the measurement of eyelid parameters, and a unified coordinate system was built into each subject. Linear and angular measurements were computed from the coordinates and were compared between the groups.
An age-related decrease was observed in the ocular width, outer canthal width, palpebral fissure height, and multiple angular measurements. This indicated upper eyelid ptosis, which reduced the lateral and superior visual field. Lateral shift of the upper eyelid arc was not observed. The lower eyelid underwent slight elevation with increasing age. Aging rendered the periorbital region esthetically less pleasing, as shown by changes in the multiple proportion indices computed. Furthermore, an intergroup comparison indicated that eyelid aging was accelerated after the age of 40 years among Chinese women.
This study used 3D photography to quantitatively analyze how eyelids in Chinese women changed with age. The anthropometric data collected could help with antiaging cosmetic surgery planning and postoperative assessment.
眼睑形态对外界环境的影响非常敏感，很容易受到衰老的影响。已有研究描述了白种人眼睑衰老的过程，但缺乏描述中国人眼睑衰老的人体测量学数据。因此，本研究旨在通过三维（3D）人体测量学定量分析中国女性眼睑衰老的影响。
本前瞻性、横断面研究共纳入 188 名健康的中国汉族女性，她们被分为 4 个年龄组。对眼睑参数进行了 3D 拍照，确定了人体测量学标志点，并为每位受试者建立了统一的坐标系。从坐标中计算出线性和角度测量值，并在组间进行比较。
观察到眼宽、外眦宽、睑裂高度和多个角度测量值随年龄增长而下降。这表明上睑出现了下垂，导致外侧和上方视野缩小。上睑弧线并未发生外侧移位。随着年龄的增长，下睑略有抬高。多个比例指数的计算结果表明，眶周区域的美观度因衰老而降低。此外，组间比较表明，中国人的眼睑衰老在 40 岁后加速。
本研究采用 3D 摄影技术定量分析了中国女性眼睑随年龄变化的情况。收集的人体测量学数据有助于制定抗衰老美容手术计划和术后评估。
