(ACTUAL 2025)
Initial: LMNOPQRST PAA PAA
Hypoxia or bronchogenic carcinoma
clubbing
myasthenia gravis
bilateral ptosis
Horners syndrome (loss of cervical sympathetics, ptosis,
miosis, and anhydrosis) or CNIII lesion.
Unilaterael ptosis
early stages of ankylosing spondylitis
Iritis/uevitis
,*Lateral Rectus*: Moves eye laterally. Abducts. (CN VI,
abducens)
*Medial Rectus*: Moves eye medially. Adducts. (CN III,
oculomotor)
*Superior Rectus*: Elevates and adducts eye. (CN III,
oculomotor)
*Inferior Rectus*: Depresses and adductors (CN III,
oculomotor)
*Inferior oblique*: Elevates eye and abducts ( CN III,
oculomotor)
*Superior Oblique*: Depresses eye and abducts. ( CN IV,
trochlear)
LR6 – SO4 – R3
Give me all muscles of the eye, what action they perform, and
what innervates them.
,*CN 3/Oculomotor*: Superior/middle/inferior rectus, inferior
oblique, and levator palpebrae muscle
*CN 4/Trochlear*: Superior oblique muscle
*CN 5/Trigeminal*: Corneal Sensation
*CN 6/Abducens*: Lateral Rectus Muscle
*CN 7/Facial*: Muscles of the eyelids and lacrimal glands
LR6 – SO4 – R3
Tell me what these CN's do regarding the eye.
Oculomotor
Trochlear
Trigeminal
Abducens
Facial
, CN III. It has been displaced by laterally by the lateral rectus
and inferiorly by the superior oblique.
If the eye is "down and out", what nerve is paralyzed?
CN IV, trochlear
What nerve is paralyzed?
No obvious resting orientation of eyeball. Patient complains
of diplopia and may develop head tilt AWAY from site of
lesion.
CN VI, abducens.
eye is stuck in adduction. What nerve is paralyzed?
Increased intracranial pressure
Papilledema indicates...
AV nicking, silver wire arterioles, widened light reflex
What will we see in the eye for arteriosclerosis?
