  Neurology: Cranial Nerve Exam Pupillary Light Response and RAPD (Yi Chang)

  Clinical Neurological Sciences, Schulich School of Medicine and Dentistry

  A neurologist looks at pupillary light response - both direct and consensual , and then relative afferent pupillary defect in a male patient with brown eyes.

  Clinician: J. Alexander Fraser, MD, FRCPC, Departments of Clinical Neurological Sciences and Department of Ophthalmology, Western University.

  Neurology: Cranial Nerve Exam Pupil Measurement (Yi Chang)

  Clinical Neurological Sciences, Schulich School of Medicine and Dentistry

  A neurologist is using a pupil gauge to measure and compare the size of pupils in a male patient with brown eyes. The shot is a close-up of the eyes.

  Neurology: Cranial Nerve Exam (Sherine)

  Clinical Neurological Sciences, Schulich School of Medicine and Dentistry

  A neurologist performs a cranial nerve exam including CN II, III, IV and VI on a patient with dark eyes. 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 in a female patient.

  Neurology: Near Visual Acuity

  Clinical Neurological Sciences, Schulich School of Medicine and Dentistry

  A neurologist is testing cranial nerve II (visual acuity) with a near card on a female patient with dark eyes.

  Neurology: Optokinetic Nystagmus and Head Thrust/Impulse Testing (Yi Chang)

  Clinical Neurological Sciences, Schulich School of Medicine and Dentistry

  A neurologist is testing for optokinetic nystagmus on a male patient with dark eyes. He is 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).

  Clinician: J. Alexander Fraser, MD, FRCPC, Departments of Clinical Neurological Sciences and Department of Ophthalmology, Western University.

• 

  Neurology: Testing Visual Fields

  Clinical Neurological Sciences, Schulich School of Medicine and Dentistry

  A neurologist is testing visual fields (cranial nerve II) on a male patient with light eyes. He tests one eye at a time, presenting the patient with either 1 or 2 fingers in all 4 quadrants.
