CLINICAL EXOPHTHALMOMETRY - A COMPARATIVE-STUDY OF THE LUEDDE AND HERTEL EXOPHTHALMOMETERS

Exophthalmometry, the quantitative assessment of the position of the g lobe in the orbit, is a clinically useful measurement. The purpose of this study was to the performance of a simple exophthalmometer that wo uld lend itself to accurate and convenient use in clinical practice. I n this study, two observers independently performed exophthalmometry o n 100 eyes using the Hertel and Luedde instruments. The results were c ompared between instruments and between observers. There was no statis tically or clinically significant difference between measurements take n with the Luedde as compared with the Hertel instrument. The Luedde e xophthalmometer has a number of advantages over the Hertel exophthalmo meter, and represents a simple, inexpensive and equally reliable means of evaluating clinically the anteroposterior position of the eye in t he orbit.
