Although the functional and anatomical differences between the left and right eyelids are important in the evaluation of age-related changes in the eyelids, they have not been described clearly as indications for surgical treatments. This study aimed to investigate how laterality of the eyelids affects evaluation of age-related changes.
Photographs of either one or both eyelids of 100 people were evaluated in four stages by 10 plastic surgeons. To investigate the consistency of the results between evaluations, surgeons evaluated the single-eyelid photographs (group U) or two-eyelid photographs (group B). It was investigated whether the difference in margin reflex distance 1, height of the upper eyelid crease, height of eyebrow, and levator contractile function were associated with mismatched evaluations.
The weighted kappa coefficient for groups B and U was 0.77 (substantial agreement). One-point difference in scores was observed in 23 cases. In the multiple logistic regression analysis, only the laterality the height of the eyelid crease was significantly different between patients whose evaluations were matched and those whose evaluations were mismatched (0.9 ± 0.1 mm versus 1.7 ± 0.2 mm; OR = 1.06, 95%CI: 1.01-1.10; = 0.01).
Besides the structure and function of each eyelid, the laterality of the height of the eyelid crease was important in the evaluation of the age-related changes in the eyelids. This factor may be important in evaluating the aesthetic and visual impressions of age-related changes in the eyelids.
尽管左右眼睑在功能和解剖学上的差异对于评估眼睑与年龄相关的变化很重要，但这些差异尚未被明确描述为手术治疗的指征。本研究旨在探讨眼睑的左右侧性如何影响对与年龄相关变化的评估。
10名整形外科医生分四个阶段对100人的单眼或双眼照片进行评估。为了研究评估结果之间的一致性，医生们评估了单眼睑照片（U组）或双眼睑照片（B组）。研究了边缘反射距离1、上睑皱襞高度、眉毛高度和提上睑肌收缩功能的差异是否与评估不匹配有关。
B组和U组的加权kappa系数为0.77（高度一致）。在23例中观察到评分有1分的差异。在多元逻辑回归分析中，只有眼睑皱襞高度的左右侧性在评估匹配的患者和评估不匹配的患者之间有显著差异（0.9±0.1毫米对1.7±0.2毫米；OR = 1.06，95%CI：1.01 - 1.10；P = 0.01）。
除了每个眼睑的结构和功能外，眼睑皱襞高度的左右侧性在评估眼睑与年龄相关的变化中很重要。这个因素在评估眼睑与年龄相关变化的美学和视觉印象方面可能很重要。
