Determination of exophthalmometry values in the North Indian population

PURPOSE: To determine exophthalmometry values (EV) in the north Indian population and to find its correlation with the age, gender, height, weight, body mass index (BMI), locality, and base value of the population. METHODS: A total of 1000 eligible participants with 504 females and 496 males with age >5 years were included in this observational cross-sectional study. Age, gender, and locality of the subjects were noted. Hertel’s exophthalmometry was performed on all subjects. The exophthalmometry values and base values were recorded. Height and weight were measured for all participants. BMI was calculated using the parameters. RESULTS: The overall mean exophthalmometry value (mm) was 14.94 ± 2.43 mm with a range between 8 and 22 mm. There was no significant difference in EV between the two eyes. Males recorded a significantly higher mean EV of 15.4 ± 2.51 mm as compared to females with a value of 14.49 ± 2.27 mm. Base value of Hertel’s exophthalmometer had a mean value 100.78 ± 5.63 mm and a range of 84–120 mm. Age, height, weight, BMI, and locality of the subjects were found to have a significant effect on the exophthalmometry as well as the base value of the population. A significant correlation was also seen between exophthalmometry values and base values of the population. CONCLUSION: Our study provided the normal exophthalmometric range for the north Indian population and also demonstrated the relationship of age, gender, height, weight, BMI, locality, and base value with the exophthalmometric values.
