Abstract

PURPOSE: Photogrammetry has been introduced as an alternative to direct measurement to obtain facial distances for a variety of anthropometric applications. The aim of this study is to establish morphological and functional value of an eye in Korean youths using specially designed computer software with digital photographic images.
METHODS
Authors measured anthropometry of an eye in Korean youths 1,449 individuals(622 males, 827 females) and analyzed stastically them.
RESULTS
The mean measurements are as follows. The diameter of cornea was 11.6+/-0.9mm in males and 11.3+/-0.9mm in females. The vertical dimension of palpebral fissure was 7.4+/-1.7mm in males and 8.2+/-1.6mm in females. The intercanthal width was 35.8+/-3.2mm in males and 34.4+/-2.9mm in females. The biocular width was 90.4+/-5.7mm in males and 87.4+/-5.3mm in females. The endocantion-superior margin of palpebral fissure distance was 12.7+/-1.4mm in males and 11.6+/-1.4mm in females. The horizontal dimension of palpebral fissure was 28.5+/-2.2mm in males and 27.4+/-1.9mm in females. The slant of palpebral fissure was 10.7+/-2.6degrees in males and 11.3+/-3.0degrees in females. The height of upper eyelid was 10.6+/-2.3mm in males and 10.7+/-2.3mm in females. The width of double fold was 2.0+/-0.7mm in males and 1.9+/-0.6 mm in females. A double fold was seen in 21.9% of males and 44.9% of females. The most frequent shape of the double fold was type IV. The most common type of epicanthal fold was type III in both males and females.
CONCLUSION
Photogrammetic measurement of large population using specially designed software could offer reliable data and these data could be useful reference for preoperative consultation, surgical planning and anthropometic study of eye.
