Prisms are made of clear plastic with easy-to-read millimeter lines on both sides. 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.

Exophthalmometer how to use

Thus a consistent measurement of proptosis or enophthalmos The exophthalmometer is an instrument designed to measure the forward protrusion of the eye. This instrument provides a method of evaluating the recording the progression and regression of the prominence of an eye caused by disorders such as thyroid disease and tumors of the orbit. An exophthalmometer should also be used to position the corneal apex ~16 mm anterior to the lateral orbital wall (Figure 4). Figure 4 . Schematic representation the eyeball position in the orbit according to anatomical relationships and mean measurements (mm): (a) distance of eyeball edge to orbit; (b) distance of pupil center to orbit; and (c) distance of corneal apex to lateral orbital rim. 2021-04-14 · E ditor,—The common method used in Hertel exophthalmometry involves aligning the corneal apex with the reference cone on the exophthalmometer and noting the position of this alignment on the millimetre scale (method 1).

2018-06-01 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. 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.

Figure 4 . Schematic representation the eyeball position in the orbit according to anatomical relationships and mean measurements (mm): (a) distance of eyeball edge to orbit; (b) distance of pupil center to orbit; and (c) distance of corneal apex to lateral orbital rim. 2021-04-14 · E ditor,—The common method used in Hertel exophthalmometry involves aligning the corneal apex with the reference cone on the exophthalmometer and noting the position of this alignment on the millimetre scale (method 1). 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.
