[The headache patient at the ophthalmologist's].

About 50 patients contact an ophthalmologist every month because of headache. Only 20 % can be helped by ophthalmological therapeutic efforts. The vast majority of those patients suffer from migraine. This contribution gives an overview of the most common causes of headache and their therapy. The ophthalmologist should not only exclude an ophthalmological cause of the headache but also contribute to making the correct diagnosis and initiating further treatment.
