Current evidence suggests that conjunctival pallor may be a more accurate indicator of the presence or absence of anemia than pallor of the palms or nail beds. 2 In addition, conjunctival pallor has been documented to appear more frequently in patients with severe anemia, and hence may be more sensitive than other signs. 3

Pallor is said to be present if the anterior rim is not markedly redder as compared to the posterior rim. Severe pallor is considered when both, anterior and posterior rims of the palpebral conjunctiva have the same very pale fleshy color.

calculated for conjunctival pallor present, borderline, and ab-sent were as follows: pallor present, LR 4.49 (95% confidence interval [CI] 1.80, 10.99); pallor borderline, LR 1.80 (95% CI 1.18, 2.62); pallor absent, LR 0.61 (95% CI 0.44, 0.80). Kappa scores of interobserver agreement between paired observers were 0.75 and 0.54. CONCLUSIONS:

The presence of conjunctival pallor, without other information suggesting anemia, is reason enough to perform a hemoglobin determination. The absence of conjunctival pallor is not likely to be of use in ruling out severe anemia. With well-defined …

2000年10月1日 · Pallor can be a helpful diagnostic clue, but pallor can be hard to detect in the elderly. Conjunctival pallor is a reliable sign, and its presence should prompt the clinician to order blood...

Different threshold levels for anemia were defined as hemoglobin ,10, 11, and 12 mg/dl. , , Main Outcome Measures: The parameters included determination of (1) the conjunctival hue, assessed as pink or pale and (2) the bulbar conjunctival blood column, assessed as full (normal), granular, or discontinuous.

Conjunctival rim pallor, conjunctival pallor, and palmar pallor have positive likelihood ratios (+LR) for anemia (hemoglobin < 11 g/dL) of 16.7, 4.7, and 5.6, which increase the post-test probability of anemia by 53%, 29%, and 33%, respectively 1–3. These findings are helpful for the diagnosis of anemia of any severity in patients of all skin ...

2010年1月1日 · We did a blind and independent comparison of physical signs (examination of conjunctivae, tongue, palms and nailbed for pallor) and the reference standard (haemoglobin estimation by an electronic cell counter).

2023年9月29日 · Pallor is skin paleness. It occurs when your skin or mucous membranes, like the lining of your eyes, turn a lighter color than normal. There are several causes of pallor. They range from emotional distress to an underlying condition, like anemia. Pallor is usually temporary. It goes away once you treat or manage its cause. What is pallor?

2013年11月15日 · Pull the lower eyelid down and compare the color of anterior part of the palpebral conjunctiva (attached to the inner surface of the eyelid) with the posterior part where it reflects off the sclera. There is usually a marked difference between the distinctly red anterior and pearly white posterior parts.
