What eye side effect is associated with digoxin?

Digoxin, a medication commonly used to treat heart conditions such as atrial fibrillation and heart failure, can indeed cause specific visual disturbances as a side effect. The correct association is with yellow vision and halos. This phenomenon occurs due to digoxin's effects on the retinas and color perception. Patients may describe experiencing yellow-tinted vision or seeing halos around lights, which can be attributed to digoxin's modulation of neurotransmitters that influence visual processing.

While blurred vision, double vision, and night blindness can occur in various ocular conditions or with other medications, they are not specifically recognized as characteristic side effects of digoxin. The unique visual disturbances associated with digoxin, including changes in color perception and the appearance of halos, are critical indicators for healthcare providers monitoring patients on this medication, as they can signal digoxin toxicity or the need for dosage adjustment. Understanding these effects is crucial for effective patient assessment and management.
