Normal periocular anthropometric measurements in the Turkish population.

PURPOSE: To evaluate the ocular and periocular anthropometric measurements of Turkish subjects.
METHODS: Corneal diameter, horizontal and vertical palpebral fissure, vertical brow-nasal distance, inter-outer canthal distance, inter-inner canthal distance, inter-pupillary distance, bridge height, lid crease, brow height, levator function, head circumference and interorbital distance were measured in 706 eyes of 353 subjects.
RESULTS: In men, the mean corneal diameter was 10.5 mm, horizontal palpepral fissure was 30.0 mm, vertical palpepral fissure was 9.7 mm, vertical brow-nasal distance was 36.9 mm, inter-outer canthal distance was 91.3 mm, inter-inner canthal distance was 30.7 mm, inter-pupillary distance was 60.6 mm, nasal bridge height was 4.7 mm, lid crease was 6.0 mm, pre-tarsal skin height was 2.3 mm, brow height was 9.7 mm, levator function was 14.4 mm, interorbital distance was 99.1 mm and head circumference was 58.0 cm. In female subjects these measurements were 10.3 mm, 30.0 mm, 9.9 mm, 35.1 mm, 90.1 mm, 30.2 mm, 60.1 mm, 4.3 mm, 5.9 mm, 2.1 mm, 9.9 mm, 14.6 mm, 95.8 mm and 55.9 cm, respectively.
CONCLUSION: In this study we obtained the anthropometric measurements of ocular and periocular structures in Turkish subjects. Knowledge of normal values in a population can be important in the manufacture of spectacles and in clinical and surgical practice.
