Here is the requested markdown conversion: # Strabismus Strabismus is a disorder in which the two eyeballs are not correctly aligned. It can be hereditary or due to birth lesions, deficient insertions of the muscles, problems in the brain's control center, or localized illness. Strabismus can be constant or intermittent. In this disorder, each eye sends an image to a different area of the brain, and as this usually ignores the messages sent by one of the eyes, the eye ignores the image and vision gets weaker, which also leads to "lazy eye" or amblyopia. It produces divergent strabismus (external) when there is a lesion of the oculomotor nerve. When at rest, which causes instability to move it laterally and inferiorly. A lesion of the abducens nerve or external ocular motor nerve (VI) causes internal strabismus. The treatment options for strabismus depend on the specific type of problem and include surgery, visual treatment (retraining of the control center) and orthoptic (training the eye muscles to straighten the eyes). ## Muscles Table | Muscle | Origin | Insertion | Action | Innervation | | :--------------------- | :------------------------------------------------------------------- | :----------------------------------------------------------------- | :---------------------------------------------------------------------------------------------------- | :------------------- | | Recto superior | Anillo tendinoso común (insert in the orbital around the optic foramen) | Región superocentral of the oculomotor | Moves the eyeballs in a superior (elevation) and medial (adduction) direction, and rotates them medially | Nervio oculomotor (III) | | Recto inferior | Same as before | Región inferocentral of the oculomotor | Moves the eyeballs in an inferior (depression) and medial (adduction) direction, and rotates them medially | Nervio oculomotor (III) | | Rectal lateral | Same as before | Lateral region of the eyeballs | Moves the eyeballs in a lateral (abduction) direction | Nervio abducens (VI) | | Recto medial | Same as before | Medial region of the eyeballs | Moves the eyeballs in a medial (adduction) direction | Nervio oculomotor (III) | | Oblicuo superior | Sphenoid bone, top and medial, to the tendinous ring in the orbit | Region of the eyeball between the superior and lateral muscles. The muscle inserts in the superolateral surface of the eyeball as a tendon that passes through the trochlea | Moves the eyeballs in an inferior (depression) and lateral (abduction) direction, and rotates them medially | Nervio troclear (IV) | | Oblicuo inferior | Maxillary bone at the base of the orbit | Eyeball region between the inferior and lateral muscles | Moves the eyeballs in the superior (elevation) and lateral (abduction) direction, and rotates laterally | Nervio oculomotor (III) | | Elevator of the upper eyelid | Roof of the orbit (upper middle of the sphenoid bone) | Skin and tarsal lamina of the upper eyelids | Raises the upper eyelids (opens the eyes) | Nervio oculomotor (III) |
