What is xanthopsia?

Xanthopsia is a form of chromatopsia, a distortion in color vision, in which objects appear more yellow than they truly are. Chromatopsias cause the observer to experience an effect similar to looking through a colored filter. In the case of xanthopsia it is based on a yellowing of the optic media, usually the lens. It has the effect of looking at the world through a yellow acetate transparency filter. There are a variety of factors that cause xanthopsia. Systemic use of drugs such as digitalis and santonin, can generate this problem. Fluorescein (used in flourescein angiography), jaundice, and hysteria are other causes. Cataract-induced changes in the lens can also bring about xanthopsia.


How does xanthopsia affect vision?

Xanthopsia makes the world appear as if viewed through a yellow filter. White objects appear more yellow and blues are less intense.

Below is a simulated view of how the world would appear to a viewer with xanthopsia. Compare the view seen without any color deficiency (below, top) with the view seen with xanthopsia (below, bottom). Notice the yellow tinge of the buildings in the background, and the relative absence of blue in the pavement.



Treatment for xanthopsia depends on its cause. If it is drug-induced, ceasing the course of the drug may eliminate the xanthopsia. In the case lenticular yellowing, the lens can be removed and replaced with an intraocular lens (IOL).
