Abstract: The purpose of this research was to study the ocular form and growth status of the Han nationality of Chinese in Sichuan Province. Four indices were determined from anthropometric and photographic methods conducted on Han aged between 2 and 25 years old. The 2154 males and 2154 females were divided into 29 groups according to their ages. The mean and standard deviation of data of each index from all groups were calculated,and the sexual differences and growth status by age were studied. The results showed that the extern-binocular breadth and interpapillary distance of males was greater than females in most groups,with significant differences shown between genders,while the interocular breadth and eyeslit breadth of males were slightly larger than females,with no significant difference between genders. Ocular growth curves increased with increasing age,and one to two peaks occurred. Ocular growth is found within certain stages,and females show faster growth status than males in some certain ages.
