Exophthalmometry in Nigerians

Exophthalmometry was studied in 100 Nigerians to determine a baseline data of normal exophthalmometry reading, and to compare this with normal values in black and white Americans. The exophthalmometry reading was higher in females than males, more in the left than the right eyes. The mean values were 13.5 mm and 15 mm in males and females respectively. Although these values are lower than those of American blacks they are similar to those of the white Americans. We suggest anatomical reasons for these differences. No correlation was found between the height and weight and degree of exophthalmometry reading in Nigerians.
