Frequently Asked Questions
Is having different-sized pupils serious?
It depends. Physiological anisocoria (present since birth, stable, <1mm difference) is harmless and affects 20% of people. New-onset anisocoria, especially with other symptoms, can indicate serious conditions like Horner syndrome, third nerve palsy, or brain aneurysm.
When should I worry about unequal pupils?
Seek immediate evaluation if anisocoria is new, greater than 1mm difference, accompanied by headache, droopy eyelid, double vision, eye pain, or occurs after head injury.
What tests are done for anisocoria?
We'll examine pupil reactions in light and dark, check for ptosis, and may use special eye drops to help diagnose the cause. Brain imaging (MRI/MRA) may be needed to rule out serious neurological causes.
Can medications cause unequal pupils?
Yes, certain medications, eye drops (especially those for glaucoma), scopolamine patches, and even touching plants like jimsonweed can cause one pupil to dilate.
Does insurance cover Anisocoria (Unequal Pupils) treatment?
Most vision and medical insurance plans cover diagnostic exams and medically necessary treatments. We accept most major insurance plans and can help verify your coverage before treatment.
