Abstract

We measured the height and length of palpebral fissure, intercanthal distance and upward deviation of lateral canthus, and ovserved presence of double lid and epicanthal fold of 316 children who had no ocular disease except refractive anomaly by the use of standardized photographic method. We also analyzed the results according to the age, sex and the degree of refractive anomaly. The mean of central height of palpebral fissure was 8.0mm and the mean of maximal height was 8.1mm. In most of cases, the point where the height became maximal was at the center of the palpebral fissure and there was no difference accorging to laterality, sex, age and the degree of refractive anomaly. The length of palpebral fissure was 20.0mm in average and there was no difference according to laterality, sex and the degree of refractive anomaly, but it increased with the increasing age. The intercanthal distance was 33.8mm in average and increased with the increasing age but was not influenced by sex and refractive anomaly. The lateral canthus was deviated upward in relation to medial canthus by 5.90 in average and it was more deviated in female than in male. There was no difference according to laterality, age and refractive anomly, The double lid was present in 28.2% of total subject and it was equally frequent in male and female, and more frequent in the older age group. The epicanthal fold was present in 54.7% of total subject and there was no difference accrding to age and sex. Most of them were epicanthus tarsalis(56.1 %) and epicanthus palpebral is type.
