Exophthalmometric values of Korean using Hertel and Naugle exophthalmometers

ABSTRACT

PURPOSE: The purpose of this study was to propose the mean exophthalmometric values of Korean using both Hertel and Naugle exophthalmometers. METHODS: We measured 176 eyes in 88 (Male 45, Female 43) normal subjects without any orbital disease using both Hertel and Naugle exophthalmometers. RESULTS: The analysis of Hertel measurements showed a mean reading of 17.2+/-1.5 mm in the male group, and of 16.1+/-1.4 mm in the female group, respectively. And the analysis of Naugle measurements showed a mean reading of 19.5+/-1.1 mm in the male group, and of 18.3+/-1.3mm in the female group, respectively. There was no difference among different age groups in male and female groups, respectively. The exophthalmometric value of Naugle measurement was significantly higher than that of Hertel measurement in both male and female groups by 2.3 mm and 2.2 mm respectively (p<0.05). CONCLUSIONS: In Korean, the exophthalmometric value of Naugle instrument is larger than Hertel in both male and female. And there is significant difference between male and female, but no difference among different age groups. These data can be useful for mean exophthalmometric value of Korean.
