The trochlear nerve, also known as cranial nerve IV, is the smallest cranial nerve and the only one that emerges dorsally from the brainstem. It innervates the superior oblique muscle of the eye, which is involved in downward and inward eye movements.
The trochlear nerve (cranial nerve IV) is responsible for innervating the superior oblique muscle of the eye, facilitating downward and inward eye movements. It is unique as the smallest cranial nerve and the only one emerging dorsally from the brainstem. Trochlear nerve palsy can result from various causes and leads to characteristic symptoms such as vertical diplopia and head tilt. Proper evaluation and management are essential for addressing trochlear nerve dysfunction.
