The main manifestations of synovial nerve palsy are diplopia, tilting of the head, and tilting of the neck. The causes of gliding nerve palsy mainly include diabetes mellitus, atherosclerosis and hypertension, aneurysm, migraine, poisoning, central nervous system tumor, and congenital causes. The gliding nerve mainly innervates the superior oblique muscle, and the function of the superior oblique muscle is to make the eyeball move inward and downward. Gliding nerve paralysis is mainly manifested as the eyeball tilting upward and outward, which causes diplopia, or diplopia, and after diplopia occurs, the tilted head and slanting neck compensates for the inability to see. The treatment of synovial nerve palsy is mainly causative treatment as well as surgical treatment. If the symptoms and manifestations of bicuspid nerve palsy occur, the clinician should be consulted and the treatment should be in accordance with the doctor’s advice.
