xanthurenic acid has been researched along with Cataract in 6 studies
xanthurenic acid : A quinolinemonocarboxylic acid that is quinoline-2-carboxylic acid substituted by hydroxy groups at C-4 and C-8.
Cataract: Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)
