Digoxin toxicity is a critical condition that arises from an excessive amount of digoxin in the body, a medication commonly used to treat certain heart conditions. One of the hallmark symptoms of digoxin toxicity is the presence of colored or halo vision, also known as xanthopsia. This visual disturbance occurs because digoxin can affect the retina and the way visual signals are processed in the brain. Patients may report seeing yellow or green halos around objects, which serves as a clear indicator of potential toxicity.

Monitoring for visual disturbances is essential during digoxin therapy because such symptoms may signal that the drug levels in the body have reached a toxic threshold, necessitating immediate medical evaluation and intervention. Recognizing these vision changes early can help prevent further complications associated with digoxin toxicity, emphasizing the importance of patient education and vigilance during treatment.
