Exophthalmos (in mm: using the same Hertel exophthalmometer and same intercanthal distance for an individual patient) Extraocular muscle involvement (degree of severity 4) Eye muscle ductions in degrees; subjective diplopia score: - Intermittent (diplopia when tired or first awakening); - Inconstant (diplopia at extremes of gaze); exophthalmometer: ( ek'sof-thal-mom'ĕ-tĕr ), An instrument to measure the distance between the anterior pole of the eye and a fixed reference point, often the zygomatic bone. Synonym(s): orthometer , proptometer , statometer [exophthalmos + G. metron, measure] The same mirror Hertel exophthalmometer (Oculus) was used in all patients, and the study was performed by one examiner. The test complied with the following rules: the exophthalmometer was positioned in such a way that the concave sections of the two frames touched the outer rims of the orbits at the lowest point. For the Hertel exophthalmometer, concordance was moderate for O1 in the 2 eyes and moderate in RE but good in LE for O2. For the Mourits exophthalmometer, this concordance was very good in RE and good in LE for O1, and good whatever the eye for O2. Objective: To compare exophthalmometry measured by Hertel exophthalmometer versus computed tomography (CT) scan. Methods: For this study, 133 patients with thyroid-associated orbitopathy (TAO) were analyzed retrospectively. Two experienced clinical observers independently measured proptosis using a Hertel exophthalmometer. Alibaba.com offers 1,561 hertel exophthalmometer products.

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.
