Which finding is most characteristic of digoxin toxicity?

Visual disturbances, especially xanthopsia, or yellow halos around lights, are the most characteristic sign of digoxin toxicity. Digoxin affects retinal processing through Na+/K+-ATPase inhibition, which can alter color perception and lead to yellow-tinged vision. While other symptoms like nausea, vomiting, or arrhythmias can occur with toxicity, the yellow-halo vision is the classic clue that points toward digoxin toxicity. Tinnitus is not typical for digoxin toxicity, and blurred vision can occur but is less distinctive than the definite yellow halos. Green halos are not the classic description for this toxicity.
