Exophthalmometer is an instrument used for measuring the degree of forward displacement of the eye in exophthalmos. The device allows measurement of the forward distance of the lateral orbital rim to the front of the cornea.Exophthalmometers can also identify Enophthalmos (retraction of the eye into the orbit), a sign of blow-out fracture or certain neoplasms.

Hertel exophthalmometer is used for precise exophthalmos measurements (e.g. Exophthalmic goiter). Sturdy construction for many years of use. Overall dimensions are 25 x 7 x 2 cm. Weight is 117 grams . Scale for orbital wall goes from 75 mm to 121 mm. The scale to measure the proptosis ranges from 0 to 35 mm. L.W.Hertel exophthalmometer IIEI&H 13.

D) NAUGLE’S EXOPHTHALMOMTER: -In case of acquired or congential asymmetry of the lateral orbital rims a Hertel exophthalmometer is misleading -This is an inferior & superior rim based instrument. -may be used when the lateral orbital rim is not exophthalmometer ppt 9 Jan 2017 Optical Co., St. Louis, wvlho made up my first very rouglh exophthalmometer according to .. requires no special procedures as the very small distance of the images to the rulers excludes Table 9 is compiled after the format of Knudtzon (15).

Read More Purpose: To present the first parallax-free exophthalmometer design. Background: Exophthalmometry is an important clinical tool. We provide a historic overview of clinical exophthalmometer designs Zur Messung mit dem Exophthalmometer wird die Patientin aufgefordert, geradeaus zu schauen. Der Untersucher schiebt die beiden Rahmen so weit zueinander, bis deren Sporen an 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.

Diagnosing exophthalmos · check how well you're able to move your eyes · use an instrument called an exophthalmometer to measure how far your eyeball

exophthalmometer. Eur J Ophthalmol. 1998 Oct-Dec8(4)246-52 ; 20 Fat removal orbital decompression. RESULTS Mean excision of 7.31 1.9 ml (range 3.25-12 ml) of orbital fat reduced proptosis on average by 4.7 2.4 mm (range 1-11 mm).

Exophthalmos is defined in dorland’s medical dictionary as an “abnormal protrusion of the eyeball; also labeled as proptosis Henderson reserves the use of the word exophthalmos for those cases of proptosis secondary to endocrinological dysfunction.

Palpate the orbit for: mass; retropulsion. 6. Test ocular motility. 3 Jan 2018 To compare the reliability of orbital parameters calculated using 2-dimensional computed tomography (CT) and Hertel exophthalmometry when The left eye examination revealed axial proptosis of 4–5 mm as measured with Hertel's exophthalmometer with upper sclera show and inferior Export to PPT 1 Jun 2020 Exophthalmometry is a method to quantify the degree of proptosis.

Limitations • Poor fixation, depressed /fractured lateral orbital rim,convergence An exophthalmometer is an instrument used for measuring the degree of forward displacement of the eye in exophthalmos. The device allows measurement of the forward distance of the lateral orbital rim to the front of the cornea. • PROPTOSIS is defined as forward protrusion of the eyeball • Proptosis of more than 21mm or more than 2mm asymmetry between the two eyes is abnormal • EXOPHTHALMOS is specifically used to describe the proptosis of eyes a/w Thyroid eye disease • ENOPHTHALMOS is defined as retrodisplacement of eye into orbit 3. Summary . Exophthalmometry is frequently used as a tool in the evaluation of proptosis. The purpose of this study was to compare the clinical usefulness of the newly developed Naugle superior and inferior orbital rim—based exophthalmometer with that of the Hertel exophthalmometer, as well as to obtain normal values and analysis of possible race and sex differences. We used the Hertel exophthalmometer to measure the degree of protrusion in 681 adults, ranging in age from 18 to 91 years.

D R E W S wall of both orbits." However, this defini tion is likely to give rise to the idea that only the transverse line through the lateral orbital rim is important; this is correct only if the lateral orbital rims are equidistant from the hypothetic frontal plane. Although an exophthalmometer may provide an objective measure, patient cooperation may limit its accuracy.
