Abstract |
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. |
