Background:
The upper eyelid margin peak, defined as the highest point of the upper eyelid margin, is a recognized component of upper eyelid contour and has been quantitatively evaluated in previous studies. Given its relevance to eyelid morphology, a standardized approach for quantitatively describing this landmark in the context of perioperative assessment of upper eyelid margin abnormalities remains of clinical interest. In this study, we use the term upper eyelid margin aesthetic point (UEMAP) to describe this anatomical feature and propose a standardized method for its quantitative assessment.
Methods:
This retrospective study included patients undergoing primary or revision double eyelid surgery for abnormalities of upper eyelid margin height and/or contour who achieved favourable postoperative aesthetic outcomes. Standardized preoperative and 6-month postoperative photographs were analysed. The horizontal distance between the UEMAP and the pupil midline was normalized by corneal width to generate the relative UEMAP distance, and preoperative and postoperative measurements were compared.
Results:
Eighty eyes from 44 patients were included. Postoperative relative UEMAP distances were distributed closer to the pupil midline than preoperative measurements. The mean absolute relative UEMAP distance decreased significantly after surgery (0.333 ± 0.100 vs. 0.049 ± 0.044, p < 0.001).
Conclusions:
This study establishes a standardized quantitative method for assessing the upper eyelid peak position. In patients with favourable postoperative outcomes, UEMAP deviation was reduced after surgery. This quantitative assessment method may provide an objective anatomical reference for perioperative evaluation during surgical correction of upper eyelid margin abnormalities.
