27
Name cranial nerve I
Ophthalmic
28
How do we test cranial nerve I
Ask about the patients sense of smell | Get them to test and identity different smelling objects
29
What is cranial nerve II called
Optic
30
How might we test cranial nerve II
-Visual acuity -Visual fields -Blind spot -Colour vision -Pupil reaction to light and accomodation (-Fundoscopy)

Name three nerves we can test together
III- Oculomotor IV- Trochlear VI- Abducens
32
How do we test cranial neves III, IV, VI
Ask paint if they have experienced blurred or double vision | Look fro symmetry of eye movement
33
Give a condition affecting cranial nerve III

36
What is Ptosis
Dropping of the eyelid
37
Why does Ptosis of the upper eyelid occur in third nerve palsy
Due to act of actin of the levator palpebrae superioris
38
Why does dilation of the pupil occur in third nerve palsy
due to loss of sphincter papillae function
39
Why causes the depressed and abducted resting eye seen in third nerve palsy
The IV and VI nerve eye muscle acting unopposed
