A 50-year-old white Caucasian woman with previously diagnosed migraine was admitted with unilateral headache and anisocoria. An initial assessment revealed no cause for this abnormality and she was thought to have mydriasis in the context of migraine. However, failure of her symptoms and signs to resolve prompted further investigation and demonstrated the diagnosis of intermittent angle-closure glaucoma.
