| Résumé : |
- Objective : To evaluate the changes in certain ocular signs because of age, among Mexican women and to compare these with those previously obtained on women of other ethnicities.
Material and methods
Photographs were taken of the faces of 203 Mexican women of different ages, under standardized conditions. These photographs allowed us to focus and define nine ocular signs, which were then graded by 15 experts and dermatologists, using standardized scales provided by a reference Skin Aging Atlas. Hence, the same protocol, previously used on 3240 women of four other ethnic origins (Caucasian : 600; Chinese : 990 ; Japanese : 1010 ; Indian : 300 ; African: 340), allowed us to compare the results obtained on Mexican women.
- Results : The severity of crow’s feet wrinkles for Mexican women shows a more intense progression with age than those of women from other ancestries. The lower eyelid wrinkles of Mexican women, that show weak or erratic changes with time, were however found to have higher and significant severity at a young age. Pigmentation disorders of their ocular area were found less pronounced as compared to those of Asian or Indian women. Eye bags were observed with similar slight changes in all five ancestries.
- Conclusion : The present work confirms that the clinical signs of age for the female eye area develop differently depending on the ethnic origins of the volunteer. |
