Overview
Fourth nerve palsy is a condition caused by weakness or paralysis of the superior oblique muscle. When present at birth, it is known as congenital fourth nerve palsy.
Causes
- Brown's syndrome: Restriction of superior oblique movement is found in Brown's syndrome, leading to difficulty elevating the eye in the adducted position
- Congenital fourth nerve palsy
- Head trauma: Superior oblique palsy is a common complication of closed head trauma
- Superior oblique myokymia is an uncommon neurological condition caused by vascular compression of the trochlear nerve resulting in repeated, brief, involuntary episodes of movement of the eye.
