ANISOCORIA

SYMPTOMS

The primary symptom of anisocoria is a noticeable difference in pupil size between the two eyes. Other associated symptoms may vary depending on the underlying cause and may include:

• Blurred vision or changes in vision quality.
• Eye pain or discomfort.
• Sensitivity to light (photophobia).
• Double vision (diplopia).
• Drooping eyelid (ptosis) in cases of neurological conditions like Horner’s syndrome.

DIAGNOSIS

Diagnosing anisocoria involves a comprehensive eye examination and evaluation of medical history. Your healthcare provider may:

• Measure pupil size using a penlight or specialized pupillometer.
• Assess the reaction of pupils to light and near stimuli.
• Conduct a thorough neurological examination to rule out underlying neurological conditions.
• Order additional tests, such as imaging studies (MRI or CT scan) or blood tests, if an underlying cause is suspected.

TREATMENT

Treatment for anisocoria depends on the underlying cause:

• Physiological Anisocoria: No treatment may be necessary if anisocoria is benign and not associated with any underlying medical condition. However, regular monitoring by an eye care professional is recommended.
• Underlying Medical Conditions: Treatment aims to address the specific cause of anisocoria. This may include medication, surgery, or other interventions targeted at managing the underlying condition.
• Symptomatic Relief: In cases where anisocoria causes discomfort or affects vision, symptom management strategies such as wearing sunglasses to reduce light sensitivity may be helpful.
