- peripheral nerves
- neuromuscular junction
- muscles
which cranial nerves are related to the eye
2-8
what is the order of the neurons going back to the visual cortex
first and second order neurons in the retina (PR and BP cells)–> third neuron (optic nerve, chiasm, optic tract) –> fourth neuron (optic radiations, and visual cortex)
what are some signs of a “sudden” attack
- ischemia
- inflammation
- infectious
what are some signs of a gradual attack
- compressive
- inherited
- degenerative
where do CN 3 and 6 meet?
cavernous sinus
vision loss with fever=
infectious or arteritic
vision loss with pain =
ischemic or demyelinating
vision loss & can’t control bladder =
MS
what are ex of affarent dysfunction
vision loss, VF loss, RAPD
what are ex of efferent dysfunction
diplopia, pupillary abnormality, ptosis, muscles of facial expression, EOMS
transient =
elevated ICP, vascular
worsens over period, then plateaus =
inflammatory and vascular
acute loss with little recovery =
ischemic
gradual worsening =
compressive or degenerative
