Answer: B - Adie’s syndrome.

Inequality between the sizes of a patient’s pupils-otherwise known as anisocoria-may be a sign of Adie’s syndrome. Adie’s syndrome is characterized by at least one tonically dilated pupil that does not react to light. Adie’s syndrome is caused by a viral or bacterial infection that causes damage and inflammation to neurons in the posterior orbit. Adie’s syndrome, however, is not life-threatening. Note that a small difference of no larger than 1 mm may be normal.
