Summary

The purpose of this research study is to learn about the variability in proptosis measurements. Measurements will be recorded using the Hertel exophthalmometer. This noninvasive tool is an instrument designed to measure the forward protrusion of the eye and may be used normally during a general eye exam. This instrument provides a method of evaluating and recording the progression and regression of the prominence of an eye caused by disorders such as thyroid disease and tumors of the orbit.
