Inferior oblique muscle
Inferior Oblique Muscle
The Inferior Oblique Muscle is one of the extraocular muscles of the eye. It is responsible for the outward and upward movement of the eye, and is the only muscle that is capable of elevating the eye when it is in an adducted position.
Structure[edit]
The inferior oblique originates from the maxillary bone near the nasal cavity, and inserts into the sclera of the eye, behind the lateral rectus muscle. It is the only extraocular muscle to originate from the floor of the orbit.
Function[edit]
The primary function of the inferior oblique muscle is to control the movement of the eye. It is responsible for ocular rotation, specifically, it abducts, elevates, and laterally rotates the eye.
Clinical significance[edit]
Damage to the inferior oblique muscle can result in diplopia (double vision) and an inability to move the eye upward and outward. This can be caused by trauma, surgery, or diseases such as Graves' disease.
