What visual disturbance can occur in patients with digoxin toxicity?

In patients experiencing digoxin toxicity, one prominent visual disturbance is the appearance of yellow or green halos around objects. This phenomenon occurs due to the drug's effects on the retina and the way it alters color perception. Digoxin affects a person's vision because it can interfere with the function of the retinal cells, leading to these characteristic color changes.

This visual disturbance is significant in a clinical context as it serves as a potential indicator of digoxin toxicity, prompting further evaluation and management of the patient's condition. Awareness of this symptom allows healthcare providers to quickly associate it with possible overdose or toxicity-related issues, ensuring appropriate interventions are taken.

The other visual disturbances, while they may occur in various conditions or due to other medications, are not specifically associated with digoxin toxicity in the same manner. Yellow or green halos are particularly indicative of the physiological changes that occur within the visual system in response to elevated levels of digoxin.
