Inferior oblique

Inferior Oblique

The Inferior Oblique (pronunciation: /ɪnˈfɪər.i.ər oʊˈbliːk/) is one of the Extraocular muscles that control the movements of the eye. The term "Inferior Oblique" is derived from Latin, with 'Inferior' meaning 'lower' and 'Oblique' referring to its angled course.

Function

The primary function of the Inferior Oblique is to help in the upward and outward movement of the eye. It is the only muscle that is capable of elevating the eye when it is in an adducted position.

Anatomy

The Inferior Oblique originates from the orbital surface of the maxilla, just lateral to the Lacrimal groove. It then passes laterally and backward beneath the Lower rectus, and is inserted onto the posterior, lateral surface of the eyeball.

Clinical Significance

Any damage or paralysis to the Inferior Oblique can lead to a condition known as Inferior oblique palsy. This condition can result in the inability to move the eye upward and outward, leading to double vision and other visual disturbances.
