Eye movement is a complex neurological function controlled by many structures located in the central nervous system. The eyeball is mobile within the orbit and its movements are carried out using 6 muscles innervated by 3 oculomotor nerves allowing to perform reflex or voluntary eye movements in all elementary directions. So-called internuclear structures allow the two eyeballs to perform combined movements. The attack of these structures during an acute or chronic neurological disease will most often cause oculomotor paralysis in one or more directions of gaze which will be perceived by the patient as double vision. So-called supranuclear structures make it possible to generate different types of eye movements: saccades, which are extremely rapid eye movements of very short duration, eye pursuit, which is a slow movement whose purpose is to follow a moving visual target and finally, certain neural circuits are intended to stabilize the gaze. Many neurological diseases can be accompanied by oculomotor abnormalities affecting saccades or ocular pursuit. These include neurodegenerative diseases characterized by diffuse neurological damage. Involvement of gaze stabilization structures is also frequently found in certain neurological diseases affecting the posterior fossa. The clinical examination of oculomotricity focuses mainly on the analysis of ocular mobility in the different directions of space by asking the subject to fix an object (for example a pen) or the index of …
