Defining Ideal Pretarsal Rolls Through a Morphometric Analysis in Asians

Background: Pretarsal rolls are a crucial aesthetic feature. Despite numerous studies conducted on periorbital aesthetics, there remains a dearth of research on the ideal pretarsal rolls.Objectives: This study aimed to investigate 4 aesthetic characteristics of ideal pretarsal rolls: presence, width, proportion, and morphology.Methods: Respondents (385, including 80 aesthetic specialists) were presented with 7 series of images of pretarsal rolls, including 2 series of pretarsal roll existence, 2 series of varying widths, 2 series of different ratios between pretarsal roll and palpebral fissure height, and 1 series about morphology. Participants were asked to rank each image within a given series from most attractive to least attractive. The rankings were then analyzed according to population demographics.Results: The majority of respondents deemed images with pretarsal rolls to be more aesthetically pleasing (P < .001) than those without such features. Additionally, pretarsal rolls with a width of 5 mm (P < .001), a ratio to palpebral fissure height of 0.5:1 (P < .001), and a crescent shape (P < .001) were perceived as the most attractive. Moreover, individuals aged 40 or younger exhibited a significant preference for images with pretarsal rolls compared to older groups (P < .001), and females displayed a greater inclination toward a medium ratio of pretarsal roll to palpebral fissure height than males did (0.5:1 P = .003, 0.618:1 P < .001).Conclusions: This study validates the optimal characteristics of pretarsal rolls, which provides insight into pretarsal roll aesthetics and holds significant implications for surgical planning and effect assessment in future periocular procedures involving pretarsal rolls.
