What does the inferior oblique muscle do?
What does the inferior oblique muscle do?
The inferior oblique muscle externally rotates, elevates, and abducts the eye.
What happens when the inferior oblique contracts?
The inferior oblique muscle originates from the floor of the orbit and inserts into the inferolateral surface of the eye. When it contracts, it laterally rotates the eye, in opposition to the superior oblique. The lateral rectus, which causes abduction of the eye, is innervated by the abducens nerve.
What is the course of nerve to inferior oblique?
Inferior oblique muscle
| Inferior oblique | |
|---|---|
| Origin | orbital surface of the maxilla, lateral to the lacrimal groove |
| Insertion | laterally onto the eyeball, deep to the lateral rectus, by a short flat tendon |
| Artery | ophthalmic artery |
| Nerve | oculomotor nerve |
How do you fix superior oblique palsy?
The treatment of choice for congenital superior oblique palsy and for an unresolved (after 6 months) acquired palsy is typically eye muscle surgery. Surgery usually minimizes double vision, reduces the unsightly upward drift of an eye, and corrects a compensatory head tilt.
How is surgery performed on the inferior oblique muscle?
All inferior oblique surgery requires the same initial steps to the point of isolation of the inferior oblique muscle (Fig s. 3 – 13). At that time, any one of several procedures can be performed (Fig s. 12 – 41). These procedures are described individually.
Is there a treatment for inferior oblique underaction?
Therapy for inferior oblique underaction includes techniques that involve the antagonist superior oblique muscle or the contralateral yoke muscle, 9,10 and they are not discussed here.
Are there any complications after inferior oblique surgery?
Significant complications following inferior oblique surgery are very uncommon. The vast majority of patients experience little or no redness or discomfort of the eye and return to normal activities within a week of surgery.
How is the anterior border of the inferior oblique identified?
The posterior border of the inferior oblique can then be identified where the white intermuscular septum contrasts with the red inferior oblique muscle (Fig. 5). The hook is rotated under the inferior oblique with the point temporally and this then is pulled forward, taking care to isolate all the fibers of the muscle (Fig. 6).
