Abstract:
Objective:To investigate the characteristics of periorbital aging in healthy Han women in outpatient department of a first-class hospital in Chongqing, and to provide reference evidence-based eye rejuvenation treatments for Han women in the area.Methods:Cross-sectional study method was used to collect clear frontal photos of healthy Han women in Outpatient Department of the First Affiliated Hospital of Chongqing Medical University from March to July 2021. Photos were stratified by age (20-29 years old, 30-39 years old, 40-49 years old, 50-59 years old, ≥60 years old) and numbered, then the same number of photos were randomly selected for each age group. The pupil was defined as the point O of the coordinate axis, the connecting line between the pupils on both sides was the x-axis, and the vertical line passing through the pupil was the y-axis. The coordinate position of the inner canthal point (A), lower tear point (B), intersection point of y-axis and lower eyelid margin (C), lowest point of lower eyelid margin (D), lateral canthal point (E), highest point of upper eyelid margin (F), intersection point of the y-axis and the upper eyelid margin(G) were measured and recorded. SPSS 25.0 software was used for analysis. Measurement data were expressed as Mean±SD. One-way ANOVA analysis was used for comparison of various indicators among different age groups. LSD test was used for paired comparison between groups.Results:A total of 500 healthy Han women in Chongqing area were included, each age group had 100 cases. Measurement results showed that A(x) increased and A(y) decreased gradually with aging, among different age groups there were statistically significant ( F=37.70, 7.97, all P<0.001), indicating that internal canthus gradually moved away from the pupil, closer to the nose and downward as people age. B(x) decreased and B(y) increased gradually with aging, among different age groups there were statistically significant ( F=44.72, 39.93, all P<0.001), indicating that the lower lacrimal point moved to the pupil, the nose and upward with aging. C(y) increased and G(y) decreased gradually with aging, among different age groups there were statistically significant ( F=230.29, 143.98, all P<0.001), which showed that the upper and lower eyelids moved closer to the pupil with aging, resulting in narrow eye fissure. D(x) and D(y) increased gradually with aging, and the differences were statistically significant among different age groups ( F=148.24, 259.24, all P<0.001). F(x) increased and F(y) decreased gradually with aging, and the difference were statistically significant among groups ( F=258.03, 152.95, all P<0.001). It indicated that the highest point of the upper eyelid margin and the lowest point of the lower eyelid margin moved towards the pupil with aging. E(x) increased and E(y) decreased gradually with aging, among different age groups there were statistically significant ( F=21.11, 21.46, all P<0.001), which indicated that the lateral canthus moved downward, closer to the nasal side with aging. The distance of inner canthus and outer canthus (AE) had no relationship with age, as there was no significant difference between groups ( F=0.99, P=0.415). The paired comparison between groups showed that the differences in all indicators between the 20-29 years old group and the ≥60 years old group were statistically significant (all P<0.05), and the differences in some indicators in some adjacent age groups had no statistical significance, but had little effect on the overall variation. Conclusions:The periorbital morphological characteristics of healthy Han women in outpatient department of a first-class hospital in Chongqing present regular changes during the aging process. The main manifestations are eyeball exposure reduction, inner canthus retreat, inner and lateral canthus ptosis, and the contour of the eye shape gradually changes from roundness to slender appearance.
