Offers a symptom-driven method of the prognosis and therapy of significant neuro-ophthalmic stipulations. With the focal point at the sufferer, this e-book emphasizes exam and applicable adjunctive reviews, together with a dialogue of diagnostic imaging modalities, and leads the reader throughout the occasionally sophisticated manifestations of neuro-ophthalmic ailment to anatomical localization of lesions and definitive prognosis. an summary of the anatomy of visible pathways is observed by way of many illustrations.
Upon crowning glory of part five, readers will be capable to:
- Describe a symptom-driven method of sufferers with universal neuro-ophthalmic court cases with a purpose to formulate a suitable differential diagnosis
- decide upon the main applicable exams and imaging, in response to symptomatology, to diagnose and deal with neuro-ophthalmic problems in a cheap manner
- investigate eye flow issues and the ocular motor procedure

Efferent Visual System (Ocular Motor Pathways) Our understanding of the anatomical pathways of the ocular motor system is incomplete. Nevertheless, detailed anatomical, physiologic, and pathologic knowledge of the ocular motor system has increased dramatically over the past several years because of results derived from primate model experiments, human electrophysiology testing, functional magnetic resonance imaging (fMRI) studies, and the clinical-pathologic-radiologic correlations of disorders in patients with documented eye movement abnormalities.
Temporal axons originate above and below horizontal raphe (HR) and take an arching course to the disc. Axons arising from ganglion cells in the nasal macula project directly to the disc as the papillomacular bundle (PM).

This point is particularly germane to interventional neuroradiologists, who may inadvertently embolize distal internal carotid artery (ICA) branches-including the central retinal artery (CRA)-while placing particles into the ECA. This event is most likely to occur in the treatment of arteriovenous malformations, but it can also occur when skull base tumors are being embolized prior to surgical resection. The most important collaterals between the internal and external circulations traverse the orbit.
