Trochlear: Associated with muscle movement. The trochlear nerve operates the superior oblique muscles, which perform many eye movements (inward, outward, and downward). Trigeminal: Associated with collecting information.The trigeminal nerveis composed of three divisions (ophthalmic, maxillary, and mandibula...
The optic nerve is another sensory nerve and is responsible for conveying information related to vision. The nerve finds its origin in the retina, at the back of the eye, in the form of axons of retinal ganglion cells. These axons leave the eye at a region called the optic disc and toge...
the pupil of the diseased eye will initially briskly contract when the unaffected eye is exposed to bright light (as the consensual response is preserved). When the affected eye is then directly exposed to the bright light, the diseased optic nerve does not mount as strong a response as the...
Cranial Nerve V is the trigeminal nerve responsible for the face's general somatic sensory innervation (GSA) through its 3 main branches, V1, V2, and V3 (ophthalmic, maxillary, and mandibular). This cranial nerve (via V3) is also responsible for motor innervation (SVE) of the muscles of ...
Cranial nerve (CN) disorders are commonly encountered in pediatric practice, since they are related to vision, eye movements, hearing and speech, facial sensation and movements, and swallowing. Localization is an important consideration in the management of these disorders, as well as the knowledge ...

These three nerves are examined as a functional unit. They are responsible for conjugate eye movements. Look first for presence of strabismus (permanent abnormal position of the eyeball). The oculomotor nerve is the major nerve controlling eye movements. In my experience, the “down-and-out” st...
