Exophthalmometer ppt

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. 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. This distance provides a metric for forward globe displacement. www.tec.in.th Learn how to say Exophthalmometry with EmmaSaying free pronunciation tutorials.

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.

Messages 51 Location Nassau Central New York Chapter Best Hertel exophthalmometer is a double ruler and mirror system, the footplates of which are placed on both lateral orbital margins simultaneously. The Hertel exophthalmometer was first described in 1905’ and has long been considered the standard for measuring the degree of prop- tosis.’ The Luedde exophthalmometer is Of all the methods that have been proposed to evaluate globe position, the Hertel exophthalmometer is the most widely used equipment [5,9].

The etiolo Se hela listan på de.wikipedia.org This instrument is used for precise exophthalmos measurements (e.g. exophthalmic goiter). The basis of the measurement for exophthalmos determination using the Hertel version is the outer orbital rim (orbital wall) and the apex of the cornea.

38 L E S L I E C. 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. The Luedde device is particularly valuable for evaluation of globe position in children, who often find it less intimidating because it is smaller and placed on the side ( Fig. 87.1 ). We used the Hertel exophthalmometer to measure the degree of protrusion in 681 adults, ranging in age from 18 to 91 years.
