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.

Hertel and Naugle exophthalmometers were used to compare the variability and reproducibility, produced by various observers. Five examiners measured fifty two eyes of twenty-six normal subjects each by using two different exophthalmometers, respectively. The average coefficient of variation among five measurements was 5.6% in the right eye, 5.2% in the left eye and 2.1% in base line by Hertel exophthalmometer. The average coefficient of variation measured by Naugle exophthalmometer was 1.9% in both eyes and 0.8% in pupillary distance. In conclusion, Naugle exophthalmometer showed less variability and better reproducibility; it is more appropriate for comparative exophthalmetry.

ReadingABSTRACT
To detect differences among the measurements of the Hertel exophthalmometers at different bar sizes and with different anufacturer`s models, exophthalmometries were performed for 27 normal subjects and 24 patients with thyroid ophthalmopathy at the three different bar sizes and with the models of three different manufacturers. The measurements decreased with the decrease of the bar size and increased with the increase of the bar size in all situations. The measurements of three different manufacturer`s models at the same bar size were different from each other. Therefore, Hertel exophthalmometries should be performed at the same bar size and with the same manufacturer`s model to find the exact changes of exophthalmos between repetitious examinations.
