What is lateral strabismus?

at rest, the eye is deviated down and laterally (is depressed and abducted) – a lateral strabismus – because the lateral rectus is unopposed. on an attempted gaze to the right, the left medial rectus will not contract to adduct the left eye (i.e., it will not move the eye toward the nose, medially).

Furthermore, what is lateral eye movement?

The lateral rectus muscle is responsible for lateral movement of the eyeball, specifically abduction. Abduction describes the movement of the eye away from the midline (i.a. nose), allowing the eyeball to move horizontally in the lateral direction, bringing the pupil away from the midline of the body.

Beside above, what is Comitant strabismus? Comitant (or concomitant) strabismus is a deviation that is the same magnitude regardless of gaze position. Noncomitant (or incomitant) strabismus has a magnitude that varies as the person shifts his or her gaze up, down, or to the sides.

Thereof, what causes strabismus?

Strabismus can be caused by problems with the eye muscles, the nerves that transmit information to the muscles, or the control center in the brain that directs eye movements. It can also develop due to other general health conditions or eye injuries. Risk factors for developing strabismus include: Family history.

Is Lazy eye the same as strabismus?

Many people make the mistake of saying that a person who has a crossed or turned eye (strabismus) has a “lazy eye,” but lazy eye (amblyopia) and strabismus are not the same condition. Amblyopia can result from a constant unilateral strabismus (i.e., either the right or left eye turns all of the time in one direction).
