Normal ranges can vary, so it is essential for a person to speak to their doctor about what their results mean. Low iron levels vary between individuals and depend on a person’s sex.

There were 462 (43.5%) females and 601 (56.5%) males. The age ranged from 6 to 70 years (mean ± SD = 20.3 ± 10.9). Subjects were divided into three age groups (years Dunsky and later Migliori & Gladstone report the mean exophthalmetry in normal African-American population to be 18.2 and 18.56 mm respectively. Quant & Woo have reported the mean value in Asian The mean normal protrusion values were 16.5 mm in white men, 18.5 mm in black men, 15.4 mm in white women, and 17.8 mm in black women. Although protrusion values above 21 mm are usually considered abnormal, we found that the upper limits of normal were 21.7 mm for white men, 24.7 mm for black men, 20.1 mm for white women, and 23.0 mm for black Aims of this study were to determine the normal range of absolute and relative Hertel exophthalmometric values (EVs) in a Chinese Han population.

The term exophthalmos is sometimes used, particularly when the proptosis is related to thyroid dysfunction. 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. The normal range is 12–21 mm.

Am J Ophthalmol. 1984; 98(4):438-42 (ISSN: 0002-9394) Migliori ME; Gladstone GJ. We used the Hertel exophthalmometer to measure the degree of protrusion in 681 adults, ranging in age from 18 to 91 years. A ‘normal range’ of discrepancies in individ- uals can be defined by the mean difference 2 two standard deviations. As the mean differences were 0.14 2 0.49 mm for right eyes and 0.12 ? 0.56 mm for left eyes (mean 5 standard devia- tion), this implies that the clinical normal range is approximately -1.00 2 +1.00 mm. Hence in METHODS: In a population-based epidemiological study, ocular protrusion values (mm) were measured in 1063 randomly selected (stratified sampling method) normal subjects using the Hertel exophthalmometer.

An exophthalmometer is a device, such as a ruler, gauge, or caliper, intended to measure the degree of exophthalmos (abnormal protrusion of the eyeball).

The term exophthalmos is sometimes used, particularly when the proptosis is related to thyroid dysfunction. 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. 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). 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).

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 Although protrusion values above 21 mm are usually considered abnormal, we found that the upper limits of normal were 21.7 mm for white men, 24.7 mm for black men, 20.1 mm for white women, and 23.0 Aims of this study were to determine the normal range of absolute and relative Hertel exophthalmometric values (EVs) in a Chinese Han population. This population-based cross-sectional study The normal values in exophthalmometry have been quoted as 10 to 23 mm (average 16 mm) in whites, and 12 to 23 mm (average 18 mm) in blacks.” The wide individual variation in the facial skeleton is perhaps the main cause of the great variation in values obtained for the normal population.’ A difference of 2 mm or greater 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.
