Exotropia

Utåtskelning

Svensk definition

En form av okulär riktningsavvikelse, där synaxlarna divergerar onormalt mycket. Felet kan bero på svaghet i musculus rectus medialis, varvid kraften från musculus rectus lateralis inte balanseras, utan ögat vrids utåt vid försök att se rakt fram.

Engelsk definition

A form of ocular misalignment where the visual axes diverge inappropriately. For example, medial rectus muscle weakness may produce this condition as the affected eye will deviate laterally upon attempted forward gaze. An exotropia occurs due to the relatively unopposed force exerted on the eye by the lateral rectus muscle, which pulls the eye in an outward direction.
