The periocular region is the most important facial feature, and it changes with age. This study assessed the age-related changes of the periocular morphologies in children, and young and middle-aged adults in Chinese Han Population.
A total of 899 volunteers of Chinese Han ethnicity were recruited: 310 children of 7 to 10 years, 309 young adults of 20 to 30 years, and 280 middle-aged adults of 50-70 years of age. Two dimensional photographs were acquired from each subject. Anthropometric measurements including eleven linear and three angular parameters were taken, and three indices were further derived. The presence of epicanthal fold and the eyelid morphology were also recorded. The above-mentioned parameters were compared across the three age groups.
Statistical significances were found between the age groups for various parameters: palpebral fissure height and width, margin reflex distance, outercanthal width, distance from the medial end of the eyebrow to the medial canthus, distance from the midtarsal to the lower end of the eyebrow, distance from the lateral end of the brow to the lateral canthus, eyebrow height, angle of endocanthion and exocanthion, palpebrae fissure index, canthal index and angular index (p<0.05). The young adult age group had greatest dimensions for almost all parameters. On the other hand, the distribution and prevalence of different types of eyelid crease were statistically significant between the age groups. A unique type of eyelid crease was identified with elderly age group of 50-70 years.
We found age-related differences in periocular parameters between children and adults of two age ranges, which included eye shapes, periocular morphologies, as well as epicanthal types. Our study provided reference data for esthetic evaluation and cosmetic surgery for East-Asian ethnics.
