Anicteric Sclerae Definition
Sclerae is medical term for White Part of Our Eye. Anicteric means Not Yellow. Therefore, Anicteric Sclerae means White Part of Eye is Not Yellow. Anicteric is antonym of Icterus. Icterus means White Part of Eye is Yellow. Patient’s eye can be yellow if his bilirubin level is higher than normal.
An adult human sclera is normally white in color, hard, fibrous, thick and turbid. Sclera is kind of protective layer of our eye. Sclera contains vitreous humor, retina, eye lenses, iris, pupil and many other important parts of human eye. Children sclera is little bit bluish, thin and in some cases, can be slightly transparent so some pigment can be visible. As with the age grows human eye can become little bit yellowish. One of the clinical symptoms of jaundice is Yellowish sclera too. Which in medical term is called icterus. Sclera can be black due to liver or kidney failure. But this is very severe and rare case.
Sclera can be yellowish due to numerous reasons. Icterus or Jaundice is one of them, liver disease is another reason, if a patient had Fluorescein Angiogram to look for retinal disease, the dye used for the diagnosis process will make the sclera look icteric too, Hepatitis is another reason, newborn babies can have jaundice but this is considered normal. As said before bilirubin level in blood converts sclera yellowish. In blood bilirubin level is normally below 1.0 mg/dL (17 µmol/L) and levels over 2–3 mg/dL (34-51 µmol/L) typically results in jaundice.
