Xanthopsia

Visual condition causing yellow-tinted vision

Xanthopsia is a visual condition in which an individual perceives a yellowish tint to their vision. This condition is often associated with certain medical conditions and the use of specific medications. Xanthopsia is a type of dyschromatopsia, which refers to any disorder of color vision.

Causes

Xanthopsia can be caused by a variety of factors, including:

• Jaundice: The accumulation of bilirubin in the blood can lead to a yellowing of the skin and eyes, which may also affect vision.
• Digitalis toxicity: Medications such as digoxin and digitoxin, used to treat heart conditions, can cause xanthopsia as a side effect.
• Cataracts: The yellowing of the lens in the eye due to cataracts can lead to a yellowish tint in vision.
• Retinal disease: Certain diseases affecting the retina can alter color perception.

Symptoms

The primary symptom of xanthopsia is the perception of a yellow tint in the visual field. This can affect the ability to distinguish colors accurately, particularly those in the blue spectrum, which may appear greenish.

Diagnosis

Diagnosis of xanthopsia involves a thorough ophthalmological examination and a review of the patient's medical history. Tests may include:

• Visual acuity test: To assess the clarity of vision.
• Color vision test: To evaluate the ability to perceive colors correctly.
• Blood tests: To check for underlying conditions such as jaundice or medication levels.

Treatment

Treatment of xanthopsia depends on the underlying cause. Options may include:

• Discontinuation or adjustment of medication: If xanthopsia is caused by digitalis toxicity, adjusting the dosage or switching medications may resolve the condition.
• Treatment of underlying conditions: Addressing issues such as jaundice or cataracts can improve symptoms.
• Vision aids: In some cases, tinted lenses may help correct color perception.

Prognosis

The prognosis for xanthopsia varies depending on the cause. If the condition is due to medication or a reversible medical condition, symptoms may resolve with appropriate treatment. However, if xanthopsia is related to irreversible retinal damage, the prognosis may be less favorable.
