Testing CN II, III, IV and VI

Clinical Neurological Sciences, Schulich School of Medicine and Dentistry

Examiner testing cranial nerve II by testing vision-central and peripheral, pupillary response (along with CN III with pupillary response), extraocular movements (CN III, IV and VI) and near response.
Testing Extraocular Movements (Close Up)

Optokinetic Nystagmus and Head Thrust/Impulse Testing

Examiner is testing for optokinetic nystagmus using an OKN strip in the horizontal and vertical directions, as well as performing a head impulse test to identify individuals with hypofunction of the vestibulo-ocular reflex (CN VIII)
