Xanthopsia

Jump to navigation Jump to search

Xanthopsia is a color vision deficiency in which there is a predominance of yellow in vision due to a yellowing of the optical media of the eye. The most common cause is digoxin's inhibitory action on the Sodium pump, and the development of cataracts which can cause a yellow filtering effect.

It has been suggested that Digitalis-derived digoxin, used to treat heart failure, induced xanthopsia responsible for the yellow tinting exhibited by many of Van Gogh's works. [1]

Xanthopsia is also a rare side-effect of jaundice, in which bilirubin may be deposited into the eye in sufficient quantity to produce a yellow tint to the vision.[1]
