  • The purpose of this study was to compare the right and left eye size, distance between two eyes, interpupillary distance on growth stage aging changes in Korean. The author divided into 5 groups according to subject's age(group A : 7~12 years, group B : 13~15 years, group C : 16~18 years, group D : 19~24 years, group E : 25~30 years). The high values of inter outer canthal distance(T) and distance between two eyes(G) were 94.30 mm, 36.66 mm at group B respectively. The ratio of identical eye size was about 10.0% in A, B, C group but 22.7% in E group. P[T-(right eye size + left eye size) / 2] was wider than IPD. Data showed that the difference was 5.72 mm in group B and 1.13 mm in group E. The reason for this is that the pupils are displaced nasally from the center of the limbal ring. This has significant meaning in ophthalmic procedures.
