The lower eyelid region is a critical component of the face. It is essential to establish anthropometric reference values for the evaluation of aging, surgical planning and assessment of outcomes in periocular esthetic and rejuvenation procedures. This study aims to provide comprehensive anthropometric data on the Chinese lower eyelid region, into account factors such as sex and age, through three-dimensional imaging analysis.
Three-dimensional facial images were obtained from 84 healthy Chinese individuals aged between 20-35 and 50-65 years, as well as eight patients aged between 20 and 35 who presented with eyelid bags. A total of 27 landmarks were identified, leading to the generation of corresponding 21 lines, 5 curves, 4 angles, 2 areas and 5 ratios. The measurements were compared among different age groups, genders and young patients with or without eyelid bags.
Compared to females, males exhibited a more elongated palpebral fissure, lower tear trough and lid-cheek junction, smaller inner and outer canthus angles, as well as a larger area and proportion of the lower palpebral region. As age progressed, the height and width of the palpebral fissure and inner canthus angle decreased gradually, which was accompanied by sagging of the tear trough and lid-cheek junction, an increase in lower eyelid area and swelling of the lower eyelid. Young patients undergoing eyelid bags demonstrated larger and more swelling lower eyelid which held clinical significance for rejuvenation surgery.
Males exhibited a higher proportion of the brow-eye unit occupied by the lower eyelid region compared to females. Elderly individuals displayed noticeable drooping of the tear trough and lid-cheek junction, accompanied by swelling in the lower palpebral region. These findings can serve as standard references for esthetic procedures and reconstructive periocular operations.

下眼睑区域是面部的重要组成部分。通过三维成像分析，建立下眼睑区域的人体测量参考值对于评估衰老、手术规划和评估眼周美容和年轻化手术的结果至关重要。本研究旨在提供全面的中国人下眼睑区域的人体测量数据，考虑到性别和年龄等因素。
从 84 名年龄在 20-35 岁和 50-65 岁之间的健康中国个体以及 8 名年龄在 20-35 岁之间有眼袋的患者中获得三维面部图像。确定了 27 个标志点，生成了相应的 21 条线、5 条曲线、4 个角度、2 个区域和 5 个比例。比较了不同年龄组、性别和年轻患者（有无眼袋）之间的测量值。
与女性相比，男性的睑裂更长，泪槽和睑颊连接更低，内、外眦角更小，下眼睑区域的面积和比例更大。随着年龄的增长，睑裂的高度和宽度以及内眦角逐渐减小，同时泪槽和睑颊连接下垂，下眼睑区域的面积增大，下眼睑肿胀。有眼袋的年轻患者下眼睑更大、更肿胀，这对年轻化手术具有临床意义。
与女性相比，男性的眉眼部单元中由下眼睑区域占据的比例更高。老年人的泪槽和睑颊连接明显下垂，同时下眼睑区域肿胀。这些发现可为美容手术和眼周重建手术提供标准参考。
