post tumor removal or thyroid decompression Delivers fast reproducible results of highest precision Hertel exophthalmometer measurements are reliable for normal patients, but can be problematic when used on patients having orbital rim fractures because the device bases its measurements from the orbital rim. In 1905, Hertel introduced the Hertel-exophthalmometer, 3 an instrument that is still is very popular nowadays. Many others have tried to make alternatives or improvements based on Hertel's design Spiegel-Exophthalmometer. Mit dem Exophthalmometer wird das Hervortreten der Augäpfel (Protrusio bulbi, Exophthalmus) in mm gemessen und quantifiziert. Es gibt zwei verschiedene Varianten: Spiegel-Exophthalmometer nach Hertel und nach Naugle. Beide Varianten besitzen ein Spiegelsystem mit integrierter Skala zum Ablesen der Messergebnisse.

The possible bias arising this way may reduce the reliability of Hertel exophthalmometer in relative exophthalmom … Interobserver agreement was analyzed for Hertel exophthalmometer and CT parameters. In patients with TAO, the association with activity and severity of TAO were also evaluated. RESULTS: GA and the GA/OA ratio measurements showed excellent interobserver agreement, whereas OA and the Hertel exophthalmometry measurements showed moderate agreement between the 2 observers. cal study, ocular protrusion values (mm) were measured in 1063 randomly selected (stratified sampling method) normal subjects using the Hertel exophthalmometer.

The basis of the measurement for exophthalmos determination using the Hertel version is the outer orbital rim (orbital wall) and the apex of the cornea. The integral refraction mirrors with millimeter scales for the left-hand and right-hand measuring halves of the exophthalmometer are calibrated so that the zero mark on the scale will be located in the plane of the resting points of the supports. In 1905, Hertel introduced the Hertel-exophthalmometer, 3 an instrument that is still is very popular nowadays.

The amount of anterior protrusion of the globe can be assessed using an exophthalmometer (Hertel, for instance (Fig. 2.36)), which is indispensable when following proptosis in a patient with thyroid orbitopathy, for example. Any enophthalmos, or inward displacement, can be measured relative to the fellow eye with an exophthalmometer.

Methods Hertel exophthalmometers take a measurement from the lateral orbital rim to the corneal apex. If a patient presents with Naugle exophthalmometers use fixation points slightly above and below the superior and inferior orbital rims (cheek Luedde exophthalmometers fix on the lateral

If a patient presents with an orbital fracture or after lateral orbitotomy, the use of Hertel exophthalmometer may be complicated because the lateral orbital rim serves as a reference point for this instrument.

Mirror Exophthalmometer Eyeball protrusion. The exophthalmometer is used for measuring and quantifying eyeball protrusion (exophthalmus) in mm. The integrated mirror system enables the examiner also to measure the sagittal distance between the cornea and the bone surface of the lateral orbital rim.

The eye is seen through the lower half and the scale through the upper, eliminating the difficulty of parallax and The study to validate the modification done to Hertel exophthalmometer was performed at the Department of Oral and Maxillofacial Surgery at our institute. Informed consent was obtained from patients; measurement in 100 volunteers was made with Hertel and modified Hertel exophthalmometer by a single observer, Exophthalmometry using an Hertel exophthalmometer appeared reliable (Pearson correlation coefficient for interobserver variation 0.89; 96% of the Hertel values measured by two observers were The Hertel exophthalmometer is used to determine the axial position of the eyes.
