What is exopthalmometer?

Exophthalmometer is a medical instrument used to measure the degree of protrusion of the eyeball from its orbit or eye socket. It helps measure the distance between the corneal surface and the lateral orbital rim.

The instrument consists of a calibrated scale, a platform for supporting the chin, and a moveable arm to measure the exophthalmos or the degree of bulging of the eye. The device is mainly used by ophthalmologists and optometrists, who are specialized in the management of eye diseases.

Exophthalmometry is a crucial tool in diagnosing and monitoring various eye disorders such as thyroid eye disease, orbital tumors, and ocular hypertensive syndrome, where changes in the protrusion of the eye are observed. The device helps determine the severity of the condition, plan treatment, and monitor the progress of treatment.
