Purpose. This study was to investigate the relationship between the palpebral fissure size and the exophthalmos in a population of Korean adult women subjects with normal eye status. Methods. From November 2012 to September 2013, The authors analyzed the morphological values in 73 Korean adults population. The test was performed using the Hertel exophthalmometer and verner califer. Analysis of subjects data were recorded using the spss version 20.0 a statistical program (IBM Co, Armonk, NY USA). Results. The average age of the 73 subjects (146 eyes) was (21.219+/-0.261)mm. the average value of palpebral fissure was (25.110+/-1.646)mm in width and (8.096+/-1.464)mm in height. The average value of exophthalmos was (15.002+/-1.922)mm. There was a significant relationship(P>0.05) in the average size between the width and height in palpebral fissure. Also, there was a significant relationship(P>0.05) in the average size between the palpebral fissure width and exophthalmos. On the other hand, there was a significant relationship(P>0.01) in the average size of palpebral fissure height and exophthalmos. Conclusions: In this study, these results suggested that the palpebral fissure and exophthalmos had a significant relationship in the average value of size in Korean adult women population.
