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. Exophthalmometry 1. Exophthalmomet ry Raju Kaiti, M. Optom Consultant Optometrist 2. Introduction Orbital disorders can be associated with forward protrusion or backward displacement of the eyes Proptosis (exophthalmos): Abnormal forward protrusion of the eyeball orbital volume is fixed, thus, excess in volume will result in protrusion of the globe Orbit is made out of BONE…It does not yield The separation of exophthalmometer noted 3)The patient told to open their eyes and look straight ahead.

Raised intraocular pressure was defined as >2mmHg above that of the non-affected eye, as measured using applanation or electronic tonometry. The ideal method of identifying reduced acuity would be to compare examination findings to a baseline, premorbid measurement. METHODS: This was a cross-sectional study, in which 673 normal subjects, between 1 and 17 years of age, randomly selected from patients presenting to our institution, were measured with an exophthalmometer. Normal volunteers also participated at a booth at the annual state fair. This website uses cookies to improve your experience while you navigate through the website.

The objective of this report was to describe a patient with Graves acropachy, a rare manifestation of Graves disease (GD) that is clinically defined by skin tightness, digital clubbing, small-joint pain, and soft tissue edema progressing over months or years with gradual curving and enlargement of the fingers.

cm uplud The Hertel exophthalmometer offers accurate and reproducible measurements and the advantage of comparing one eye with the other during the same examination. In Hertel exophthalmometry , the distance between the two lateral orbital rims is engraved on the horizontal bar, which carries the sliding mirrors. 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).

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). Proptosis 1. EVALUATION OF A CASE OF PROPTOSIS DR ARPITA 2. • 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 The Hertel exophthalmometer is used to determine the axial position of the eyes. The instrument is placed on the lateral orbital rim of each side, using as small of a base as possible. Depending on the device, lines on the prism are placed into position by moving the examiners view point to determine the measurement.

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). Side effects were few, limited only to ocular motility disturbances. There was no significant effect on visual fileds.

The scale to measure the proptosis ranges from 0 to 35 mm. L.W.Hertel exophthalmometer IIEI&H 13. 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.

Depending on the device, lines on the prism are placed into position by moving the examiners view point to determine the measurement. The general idea is to measure the globe position to determine whether or not globe malposition is present. Globe position is typically measured clinically using a Hertel exophthalmometer device which measures the distance from the lateral orbital rim to the corneal apex.
