Visual disturbances in neurology

The eyes, ocular motor system and visual pathways of the central nervous system are frequent sites of neurological disease. As patients with visual symptoms often present first to an ophthalmologist or optometrist, it is as important for these two specialists to have some knowledge of neurological disorders affecting vision as it is for the neurologist and general physician. This article outlines the basic assessment of a patient presenting with impaired vision, either as a primary complaint or as part of a more generalized neurological or systemic disorder.
