The Superior Oblique Muscle is one of the six extraocular muscles responsible for eye movement. It originates from the back of the eye socket and passes through a fibrous loop called the trochlea. Its primary function is to help rotate the eye downward and outward, allowing for better vision during activities like reading or looking down. This muscle is innervated by the trochlear nerve (cranial nerve IV). Dysfunction of the Superior Oblique Muscle can lead to conditions such as diplopia, where double vision occurs, often requiring medical evaluation or treatment to restore proper eye alignment and function.
