This instrument provides a method of evaluating the recording the progression and regression of the prominence of an eye caused by disorders such as thyroid disease and tumors of the orbit.This instrument consists of a horizontal calibrated bar with movable carriers at each side. Marco Prism Exophthalmometer The Marco PRISM EXOPHTHALMOMETER is designed for accuracy and simplicity in the measurement of the exophthalmos.Prisms are made of clear plastic with easy-to-read millimeter lines on both sides. The eye is seen through the lower half and the scalethrough the upper, eliminating the difficulty of parallax and facilitating a rapid determination of protrusion.The Marco Exophthalmos, also known as proptosis, is the medical term for bulging or protruding eyeballs. It can affect 1 or both eyes and is most often caused by thyroid eye disease. The current clinical gold standards for measuring abnormal eyeball protrusion is the Hertel exophthalmometer, which is prone to reading errors and inconvenient to use.

The device allows measurement of the forward distance of the lateral orbital rim to the front of the cornea. Exophthalmometers can also identify enophthalmos (retraction of the eye into the orbit), a sign of blow-out fracture or certain neoplasms. Naugle exophthalmometer is superior and inferior orbital rim-based instrument.

Although several limitations have been identified for its use, the Hertel exophthalmometer is still the most widely used instrument for measuring exophthalmos, due to its easy operation, low

Have patient gaze at a fixation target Proptosis is measured using an exophthalmometer. This device takes a millimeter measurement of the distance between the anterior cornea and the temporal orbital rim for each eye. For an individual patient the measurement base is the distance between the two temporal orbital rim margins. The Hertel exophthalmometer is used to determine the axial position of the eyes. The instrument is placed on the lateral orbital rim of each side, using as small of a base as possible. Depending on the device, lines on the prism are placed into position by moving the examiners view point to determine the measurement.

Thus a consistent measurement of proptosis or enophthalmos Henry B. Burch, Rebecca S. Bahn, in Endocrinology: Adult and Pediatric (Seventh Edition), 2016 Exophthalmometry. Proptosis may be quantitated with an exophthalmometer, an instrument that measures the position of the globes in relation to the lateral orbital rim.The device is easy to use and is helpful in documenting the results of treatment. What is exophthalmometry?Exophthalmometry is a method for measuring globe (eye) position for a patient. The general idea is to measure the globe position to determine whether or not globe malposition is present. Globe position is typically measured clinically using a Hertel exophthalmometer device which measures the distance from the lateral orbital rim to the corneal apex. The exophthalmometer is an instrument designed to measure the forward protrusion of the eye.
