The detail to which a neuro-ophthalmological examination can be undertaken clearly depends on the facilities available to the examiner. Examination in a fully furnished ophthalmology suite is entirely different to bedside examination with nothing but a Snellen chart, a red pin, and an ophthalmoscope. In this article we will try to provide a balance between the “ideal” and what is
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.
6)From mirrors located at each end findings are recorded in mm. 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.
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. • Measure proptosis with Hertel and / or Luedde, Mourits exophthalmometer. • Diagnose orbital cellulitis. • Establish the diagnosis of orbital tumour (intra-orbital and lacrimal gland).
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.
Globe position is typically measured clinically using a Hertel exophthalmometer device which measures the distance from the lateral orbital rim to the corneal apex. This distance provides a metric for forward globe displacement.

Although less accurate, one can also measure these, using a clear plastic ruler, by placing it at the lateral canthus (where the upper and lower lids meet) and holding it parallel to the patient's nose. The detail to which a neuro-ophthalmological examination can be undertaken clearly depends on the facilities available to the examiner.

We used the Hertel exophthalmometer to measure the degree of protrusion in 681 adults, ranging in age from 18 to 91 years. The 327 white and 354 black subjects had no history of orbital or endocrine disease, severe myopia (more than -7 diopters), or buphthalmos.
