A
  • Reflexes
    Focus on the wall behind me, I will shine a light but you
    continue to focus on the wall.
  • Visual field
    Keep focusing on the wall behind me and I will introduce
    my finger into your field of vision and bring it closer to
    you, would that be okay?
  • Visual acuity (snellen chart)
    Start from the top, read as many lines as possible

Q

When checking for optic nerve reflexes, what do you look for?

A

Check for:

  • Direct (one eye)
  • Consensual (both eyes)
17
Q

When checking for optic nerve visual field, what do you look for?

A

Accomedation reflex

  • Constriction
  • Convergence

Ask the patient to keep at the wall in front of them and then look at the tip of the pen

18
Q

How do you check trigeminal (II) nerve?

A 
- Cutaneous sensation 
   Use cotton wool/pin prick to check sensation on both 
   sides:
       - Forehead 
       - Maxilla (cheek)
       - Mandible (jaw)
- Motor 
  Ask patient to chew motion, side to side. 
  Chinch their teeth and feel the following muscles:
       - Temporalis 
       - Masseters 
- Reflex 
  Relax their jaw and perform jaw jerk
19
Q

Why is jaw jerk performed and what is it indicative of if positive?

A

Jaw jerk is performed when checking trigeminal nerve.

  • Negative: absent or very slight
  • Positive: if jaw moves upwards briskly

Positive jaw jerk is indicative of upper motor neurone lesion of the 5th cranial nerve.

20
Q

How do you check facial (VII) nerve?

A
  • Inspection
    • Flattening of the nasal groove
    • Unilateral drooping of the mouth
    • Forehead wrinkling
  • Movements:
    • Look up and wrinkle your forehead
    • Show me your teeth
    • Close your eyes, as tightly as you can, stop me from
      opening them

- Obstruct your hearing in one ear and whispering
a word into your other ear.
- I would like you to repeat that work to me.
