Axantopsia
Definition
A rare medical term or neologism of hybrid structure used to describe a congenital or acquired visual anomaly characterized by the functional inability to perceive shades of yellow (or associated with severe forms of partial achromatopsia). It originates from the combination of the Greek elements 'a-' (privative), 'xanthos' (yellow), and 'opsis' (vision), being a terminological variant synonymous with axantopia or clinical forms of tritanopia.
