Cranial Nerves Assessment
Cranial Nerve III: Oculomotor
Pupil constriction is tested with the room darkened. The nurse brings the penlight in from the side or from above or below the client’s head and shines the light in the client’s eye. The pupil should constrict and stay constricted. This is direct response. The response in the other eye is consensual and is less than the eye being tested. Pupils should be equal, round, regular, and react to light and accommodation. (PERRLA).
Cranial Nerve IV: Trochlear
Eye movement (inferior and medial) is tested with assessment of cranial nerve VI.
