[入口詞] Alternating Exotropia
[主題詞] Exotropia
[英文釋義] 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.
