xanthopsia

Thân thiện

A patient with xanthopsia sees the white walls of the room as yellow.

Definition

Noun: A visual condition or defect where objects are perceived as having a yellow tint or hue. This symptom can sometimes occur in association with jaundice or as a side effect of certain medications or substances.

Usage

The term is used in medical and clinical contexts to describe a specific type of chromatic aberration in vision. It is a symptom, not a disease itself. - The patient reported xanthopsia, describing the white walls as looking yellow. - Xanthopsia is a known potential side effect of that particular heart medication.

Advanced Usage

• Pathological Context: Xanthopsia can be a symptom of various conditions, including liver disorders (like jaundice, where bilirubin causes yellowing), digitalis toxicity, or poisoning.
• Descriptive Use: It can be used descriptively in non-medical writing to convey a character's altered perception.
  • In his feverish state, a mild xanthopsia set in, bathing the room in a sickly gold light.

• Related Medical Terms:
  • Cyanopsia: A condition where objects appear bluish.
  • Erythropsia: A condition where objects appear reddish.
  • Chloropsia: A condition where objects appear greenish.

Synonyms

Antonyms

Notes

Xanthopsia is a rare and specific term. It is important to distinguish it from general color blindness or more common visual disturbances. The condition is typically temporary and linked to an underlying cause.
