Quick Overview

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 scale
through the upper, eliminating the difficulty of parallax and facilitating a rapid determination of protrusion.
The Marco Prism Exophthalmometer has a silver hammer-tone finish and comes complete with a storage case with red velvet liner.

3) The apex of the cornea of each eye is superimposed on the millimeter scale on the prisms.
4) Align the two red lines on each prism to determine and record the measurement.
5) Note: The distance along the horizontal bar should be recorded so that the prisms can be accurately
reset for comparison of future readings.
