Visual Loss: Optic Neuropathies
The diagnosis of optic neuropathy is usually considered under two circumstances: (1) when visual loss is associated with an anomalous, swollen, or pale optic disc or (2) when the fundus…
Optic Disc Swelling: Papilledema and Other Causes
This chapter reviews the distinction between papilledema (disc swelling secondary to increased intracranial pressure), disc swelling associated with optic neuropathy, and disc elevation due to pseudopapilledema. The fundus appearance of…
Retrochiasmal Disorders
The retrochiasmal afferent visual pathways include the optic tract, lateral geniculate nucleus (LGN), optic radiations, and striate cortex. The most common neuro-ophthalmic presentation of a unilateral retrochiasmal disturbance is a…

Key wordsMaculopathies, maculopathies that mimic optic neuropathy, retinal vascular occlusions, acute outer retinopathies, cancer-associated retinopathies, toxic and hereditary retinopathies, retinal manifestations of neurologic and systemic diseases While a comprehensive…
The Neuro-Ophthalmic Examination
The neuro-ophthalmic examination combines ophthalmic and neurologic techniques to assess the patient’s vision, pupillary function, ocular motility, eyelids, orbits, fundus appearance, and neurologic status. In most cases, after obtaining the…
The Neuro-Ophthalmic History
As in any field of medicine, the neuro-ophthalmic history guides the physician’s examination and differential diagnosis. From the beginning of the history taking, the physician should attempt to categorize the…
Visual Loss: Overview, Visual Field Testing, and Topical Diagnosis
The afferent visual pathways encompass structures that perceive, relay, and process visual information: the eyes, optic nerves (cranial nerve II), chiasm, tracts, lateral geniculate nuclei, optic radiations, and striate cortex…
