A 46-year-old woman under investigation for three episodes of amaurosis
fugax in the left eye proved to have a left anterior-middle fossa dural
arteriovenous malformation with pial venous drainage. The malformation
received its main supply from the left middle meningeal artery, but its
anterior part was fed by the recurrent meningeal branch of the left
ophthalmic artery. Transient episodic lowering of retinal arterial pressure
due to shunting of blood from the ophthalmic artery to the malformation is
the most likely explanation for the occurrence of amaurosis fugax,
indicating that this symptom occurs in some patients on a hemodynamic
basis.
