[exophthalmos + G. metron, measure]exophthalmometerInstrument for measuring the amount of exophthalmos (or enophthalmos). There are several types, the most common being the Hertel exophthalmometer: it measures the distance between the corneal apex and the apex of the deepest angle of the lateral orbital margin of both eyes simultaneously, using either mirrors or prisms and a superimposed millimetre scale. The normal range varies between 12 mm and 21 mm and a difference between the eyes greater than 2 mm is suspicious. |
