XANTHOPSIA

xanthopsia: translation

Also known asyellow visionandyellowish vision. The term xanthopsia comes from the Greek wordsxanthos(yellow) andopsis(seeing). It is used to denote a *chromatopsia (i.e. a temporary aberration of colour vision) in which whites are seen as yellowish and blues as less intense. Pathophysiologically, xanthopsia is associated primarily with changes in the eye's lens system. Etiologically, it is associated primarily with cataract, and with systemic exposure to therapeutics such as thiazides, sulphonamides, barbiturates, digitalis, and picric acid. In classic references xanthopsia is also attributed to jaundice and to hysteria. Xanthopsia tends to be classified as an *entoptic phenomenon. The term is used in opposition to the terms *cyanopsia (blue vision), *chloropsia (green vision), *erythropsia (red vision), and *ianothiopsia (violet or purple vision).
