Proptosis refers to the forward displacement of the eyeball beyond the orbital margin with the patient looking straight ahead. The reference line for measurement of proptosis is the interzygomatic line (a line is drawn at the anterior portions of the zygomatic bones): the distance from this line to the posterior sclera is normally 9.9 +/- 1.7 mm 2; the distance from this line to the anterior surface of the globe should be <23 mm 4 The mean normal protrusion values were 16.5 mm in white men, 18.5 mm in black men, 15.4 mm in white women, and 17.8 mm in black women.
As computerised tomography is now accepted as a method of choice for the investigation of suspected orbital masses, measurement of the degree of proptosis (exophthalmos) should be useful in assessing response to therapy.

Another resource suggests that the terms exophthalmos and proptosis can be used to describe eyes appearing to bulge out of the face due to an increase in the volume of the tissue behind the eyes. For an individual patient the measurement base is the distance between the two temporal orbital rim margins. It can be classified into three types, including relative proptosis (comparison between the right eye and left eye), comparative proptosis (compared with earlier measurements in the same eye) and absolute proptosis (compared with ''normal" values in the .

Methods: In a prospective randomized study of orbital radiotherapy for Graves' ophthalmopathy, measurements of proptosis were made on the same visit by an endocrinologist and an ophthalmologist using the Krahn exophthalmometer and by a technician using orbital computed tomography . Naugle exophthalmometer measures the difference in proptosis between the two eyes rather than absolute measure with the Hertel method. The original description in 1905 by Emil Hertel of a device to measure proptosis had only two mirrors; it was actually never made because it was difficult to see the scales which measure the position of the cornea.

The advantages of the Hertel exophthal- mometer include the ability to measure both eyes simultaneously, and the measurement of the distance between lateral orbital rims.
The main symptom of proptosis is an abnormal protrusion of the eyes. At week 24 after teprotumumab therapy completion, patient had proptosis measurement of 18 mm, Gorman diplopia score of 0 and a CAS of 0. Under normal conditions this distance is roughly 18 mm, there may be individual and racial variations.

Aim and Objectives: This prospective study was aimed at using magnetic resonance imaging (MRI), to determine interzygomatic distance, distance between the anterior and posterior borders of the globes and the interzygomatic line (IZL), and then using these parameters to determine the normal position of the ocular globes within the orbits.
• 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 Average proptosis for the total cohort was 15.88 ± 2.49 mm, with 582 eyes measured. If measurements are out of the normal range, however, other tests will be conducted, possibly including an MRI, blood work, ultrasound, or even a biopsy. Treatment modality was decided based on radiological and histopathological examination reports, which included medical surgery, radiotherapy, and chemotherapy or a combination of all. Conclusion: The results obtained from this study may help ophthalmologists, radiologists, and other clinicians to quantitatively evaluate patients with enophthalmos, exophthalmos, or other changes in the orbital morphology.

Prevention and treatment information (HHS). The distance between anterior border of the globe (corneal apex) and IZL which is referred to as Hertel-index, distance between posterior border of the globe and IZL, and length of the IZL were measured at the level of the lens for 340 normal ocular globes of 170 patients on T1-weighted MRIs.

Exophthalmometers can also identify enophthalmos (retraction of the eye into the orbit), a sign of blow-out fracture or certain neoplasms. A similar appearance, seen in endocrine dysfunction, especially thyroid disorders, is called 'exophthalmos'. New York: Thieme Stuttgart; 2000. p. 104-7.

Exophthalmos (also called exophthalmus, exophthalmia, proptosis, or exorbitism) is a bulging of the eye anteriorly out of the orbit.Exophthalmos can be either bilateral (as is often seen in Graves' disease) or unilateral (as is often seen in an orbital tumor).Complete or partial dislocation from the orbit is also possible from trauma or swelling of surrounding tissue resulting from trauma.
