Study Notes
Cranial Nerve Palsy and Multiple Nerve Palsies
- Symptoms of cranial nerve 3 palsy include double vision, blurry vision, reduced peripheral vision, headaches, and dizziness
- Oculomotor nerve palsy affects the extraocular muscles, causing eye movement and pupil dilation issues
- Etiologies of cranial nerve 3 palsy include vascular, compressive, traumatic, and inflammatory causes
- Tests to evaluate cranial nerve 3 palsy include case history, visual acuity, cover test, and pupil testing
- Trochlear nerve palsy affects the superior oblique muscle and can result from congenital or acquired causes
- Etiologies of cranial nerve 4 palsy include congenital abnormalities, head trauma, and microvasculopathy
- Tests to evaluate cranial nerve 4 palsy include case history, cover test, and pupil testing
- Abducens nerve palsy affects the lateral rectus muscle and can result from trauma, aneurysm, ischemic, or idiopathic causes
- Lesions of the abducens nerve cause ipsilateral paresis of the lateral rectus and convergence strabismus
- Multiple cranial nerve palsies can affect CN 3, 4, 5, 6, or cause Horner's syndrome, with cavernous sinus and orbital apex syndrome being common causes
- Other forms of paralysis include single muscle palsies and double elevator palsy, each with distinct presentations and etiologies
- Differential diagnoses for single muscle palsies include atypical presentations, myogenic causes, and trauma-related conditions such as blowout fractures
