Abstract
It is not uncommon for the ophthalmologist to be the first to diagnose neurological pathology. Some of these conditions will be amenable to catheter-based neurointervention. Among these conditions, cerebral aneurysms and carotid-cavernous fistulas are the two most common conditions. Idiopathic intracranial hypertension is another disease that may be amenable to neurointerventional treatment, although its role remains controversial. Cerebral aneurysms have been described in previous chapters (see Chaps. 10.1007/978-1-4939-1942-0_10 and 10.1007/978-1-4939-1942-0_11) and only the ophthalmologic manifestations are described here. The remainder of the chapter will focus on the anatomy, clinical presentation, imaging characteristics, and management of the carotid-cavernous fistula and idiopathic intracranial hypertension.
