The normal range is 12–21 mm. Upper normal limit for people of African origin is a little higher, about 23–24 mm. A difference greater than 2 mm between the eyes is significant. In children and teenagers mean exophthalmometric measurements increase with age: Less than 4 years old (13.2 mm), 5–8 years old (14.4 mm), 9–12 years old (15.2 mm) and 13–17 years old (16.2 mm).

Subjects were divided into four age groups (5–7, 8–11, 12–15 and 16–18 years) and also divided by gender. The lowest recorded exophthalmometric measurement for an eye was 8 mm, and the highest measured value was 20 mm. For all our subjects, a mean of both eyes (OU) was 14.91 ± 1.68 mm.

Prisms are made of clear plastic with easy-to-read millimeter lines on both sides. The eye is seen through the lower half and the scale through the upper, eliminating the difficulty of parallax and facilitating a rapid determination of protrusion.

A difference greater than 2 mm between the eyes is significant. In children and teenagers mean exophthalmometric measurements increase with age: Less than 4 years old (13.2 mm), 5–8 years old (14.4 mm), 9–12 years old (15.2 mm) and 13–17 years old (16.2 mm). The normal amount of ocular protrusion as measured (with an exophthalmometer) from the lateral orbital rim to the corneal apex is 14–21 mm in adults; protrusion greater than 21 mm or a 2-mm change is abnormal. Normal values of hertel exophthalmometry in children, teenagers, and adults from Tehran, Iran.

2017-10-17 Purpose: The normal distribution of exophthalmometry measurements in a U.S. pediatric population was determined as a reference for clinical practice. 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 The purpose of any exophthalmometer is to measure the distance (exophthalmos) between the front most surface of the cornea compared to the external orbital canthus (orbital notch). The normal range varies between 12 mm and 21 mm.

Normal exophthalmometric values in adult population of ABC Region, Sao PURPOSE: To determine the normal exophthalmometry of both eyes and of the The degree of proptosis was measured using a Hertel exophthalmometer. The normal value for Filipinos is between 10 to 19.5 mm.

Your doctor may also measure the degree of bulging with a ruler or a special instrument called an exophthalmometer. If measurements are outside of normal ranges, more testing may be done, especially if the bulging only affects one eye. Tests may include an MRI, bloodwork, an ultrasound, or even a biopsy.

The purpose of any exophthalmometer is to measure the distance (exophthalmos) between the front most surface of the cornea compared to the external orbital canthus (orbital notch). The normal range varies between 12 mm and 21 mm. A difference between the eyes greater than 2 mm is considered significant. 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. HERTELS exophthalmometer • Most commonly used • The Hertel is designed such that both lateral orbital margins and corneal apices are visible to examiner in rapid succession (almost simultaneously).

In children and teenagers mean exophthalmometric measurements increase with age: Less than 4 years old (13.2 mm), 5–8 years old (14.4 mm), 9–12 years old (15.2 mm) and 13–17 years old (16.2 mm).
