Orbital muscles are the muscles that control the movement of your eyeball. They are responsible for directing your eye in different directions so you can see properly. When these muscles are injured—specifically, when they tear—it can lead to pain, double vision, misalignment of the eyes, and other vision problems. Orbital muscle tears can happen because of trauma (like a sports injury or an accident), overuse, or even as a complication of surgery.
Anatomy of the Orbital Muscles
There are six extraocular muscles that work together to control eye movement. Below is a simple overview of each, including their structure, location, origin, insertion, blood supply, nerve supply, and functions.
A. Superior Rectus
-
Location: Upper part of the eye.
-
Origin: Arises from the common tendinous ring (annulus of Zinn) at the back of the orbit.
-
Insertion: Attaches to the top (superior) surface of the eyeball.
-
Blood Supply: Receives blood from branches of the ophthalmic artery.
-
Nerve Supply: Innervated by the oculomotor nerve (cranial nerve III).
-
Functions: Mainly elevates the eye (moves it upward) and contributes to intorsion (rotating the top of the eye inward) and adduction (moving the eye toward the nose).
B. Inferior Rectus
-
Location: Lower part of the eye.
-
Origin: Also arises from the common tendinous ring.
-
Insertion: Attaches to the bottom (inferior) surface of the eyeball.
-
Blood Supply: Supplied by branches of the ophthalmic artery.
-
Nerve Supply: Innervated by the oculomotor nerve (cranial nerve III).
-
Functions: Mainly depresses the eye (moves it downward) and assists in extorsion (rotating the top of the eye outward) and adduction.
C. Lateral Rectus
-
Location: On the side of the eye, toward the temple.
-
Origin: Begins at the common tendinous ring.
-
Insertion: Inserts on the outer (lateral) surface of the eyeball.
-
Blood Supply: Receives blood from the ophthalmic artery’s lateral branches.
-
Nerve Supply: Innervated by the abducens nerve (cranial nerve VI).
-
Functions: Abducts the eye (moves it outward, away from the nose).
D. Medial Rectus
-
Location: On the inner side of the eye, near the nose.
-
Origin: Originates from the common tendinous ring.
-
Insertion: Attaches to the inner (medial) surface of the eyeball.
-
Blood Supply: Also supplied by branches of the ophthalmic artery.
-
Nerve Supply: Innervated by the oculomotor nerve (cranial nerve III).
-
Functions: Adducts the eye (moves it inward, toward the nose).
E. Superior Oblique
-
Location: Runs from the back of the orbit, curving to the top outer side of the eye.
-
Origin: Originates from the sphenoid bone near the orbit’s back.
-
Insertion: Inserts on the upper part of the eyeball after passing through a fibrous loop called the trochlea.
-
Blood Supply: Supplied by branches of the ophthalmic artery.
-
Nerve Supply: Innervated by the trochlear nerve (cranial nerve IV).
-
Functions: Primarily causes intorsion (inward rotation) and helps depress and abduct the eye.
F. Inferior Oblique
-
Location: Runs from the front and inner side of the orbit, then passes under the eye.
-
Origin: Begins near the front of the orbit.
-
Insertion: Inserts on the outer (lateral) surface of the eyeball.
-
Blood Supply: Receives blood from branches of the ophthalmic artery.
-
Nerve Supply: Innervated by the oculomotor nerve (cranial nerve III).
-
Functions: Causes extorsion (outward rotation), elevates, and abducts the eye.
Key Functions of Orbital Muscles
-
Elevation: Lifting the eye upward.
-
Depression: Moving the eye downward.
-
Abduction: Moving the eye away from the nose (outward).
-
Adduction: Moving the eye toward the nose (inward).
-
Intorsion: Rotating the eye inward.
-
Extorsion: Rotating the eye outward.
Types of Orbital Muscle Tears
Orbital muscle tears can vary in severity and appearance. Here are some common types:
-
Partial Tear: Only a portion of the muscle fibers are torn.
