Occulomotor nerve palsy causes all of the following EXCEPT
Upward & lateral detion of eyeball doesn't happen in oculomotor nerve palsy. Oculomotor nerve (CN III) innervates all EOM except: Superior oblique (CN IV) & lateral rectus (CN VI) Paralysis of CN III results in: Ptosis (due to LPS involvement) Lateral & downward detion of eye (LR & SO are the only muscles intact, unopposed action) Dilatation of pupil (paralysis of sphincter pupilae muscle) Loss of accommodation reflex (paralysis of ciliary muscles)
Ptosis
Mydriasis
Upward and lateral detion of eyeball
