Explanation:
Detailed explanation-1: -Diseases or injuries to the fourth cranial nerve can cause the superior oblique muscle to be paralyzed. The name for this condition is fourth nerve palsy. Other names for it are superior oblique palsy and trochlear nerve palsy. You may have fourth nerve palsy from birth, or you may develop it later.
Detailed explanation-2: -One common manifestation of a superior oblique palsy is double vision, which is relieved by tilting the head towards the unaffected side. Tilting the head toward the affected side would worsen double vision by leading to greater separation of the two images seen by the patient.
