What is the lower oblique?
The lower oblique muscle is one of the six thin, extra -peak muscles responsible for eye movement. Esing on the maxillary bone in the inner floor of the eye plinth, lower oblique muscle waveforms to attach to the glazier of the eye at the point between two muscles that connect to the lower and side poles of the eye, lower and side rectics. The primary effect of the lower oblique is the outer rotation of the eye, in which the superior pole of the eye is turned counterclockwise. In addition, the muscles also raise the eye up and turn the eye out. The lower division of the third cranial nerve, the oculomotor nerve, provides a nervous supply to the upper oblique muscles.
Strabism concerns imbalance in the action of extra -peak muscles with associated deviations in eye alignment. The "exaggeration" of the lower oblique muscle can coexist with other children's eye alignment, either by the eyes that crosses or eyes that will appear. Excessive action of this muscle causes excessive eye improvement when the patient turns the eye in. Surgery to Oslobení svalu může tento stav zmírnit.
If the eyepiece is damaged, the patient may experience the weakness of the lower oblique muscle. As a result, the eye rotates clockwise and creates an inclined image. To avoid double vision, the patient leans his head towards the side with an inactive lower oblique muscle. When the patient tries to look up and inside, the affected eye does not look as much as it should. The treatment for lower oblique polio includes weakening of the contradictory oblique muscles on the same eye or weakening of the superior rectus muscle on the opposite eye.
Oculomotor damage is influenced not only by lower oblique, but also excellent rectus, lower rectus and medial rectus muscles. These muscles move the eye up, down and in. When there is a deteriorated intake of nerves to all these muscles, the eye remains in the position of the outer and down position. The eye will not be able to move in or up around the middle lineIE.
Damage to the fourth skull nerve, the trochlear nerve, disrupts the nervous supply of superior oblique muscle. A defender of a superior oblique muscle creates a clinical picture that resembles an excessive inferior oblique muscle. The patient usually leans his head from the affected side. A significant double vision occurs if the patient tilts his head to the affected side.
