Intraoperative Indirect Ophthalmoscopy: A Novel Solution to Monitor Ophthalmic Artery Flow During Aneurysm Surgery

Intracranial aneurysms can be complicated by their relative location within the skull base. Most aneurysms can be treated using either an endovascular or transcranial approach. Pretreatment analysis using test occlusion is often standard in cases where clipping or coiling an aneurysm may result in neurological deficit. In addition intraoperative Doppler analysis can be utilized to determine if clip placement has resulted in reduced flow through the vessel.
