What is intermittent exotropia?

Intermittent exotropia refers to the condition that the visual axis is often separated and sometimes can maintain normal position.

Intermittent exotropia is usually caused by the separation of the visual axis of children or adolescents when viewing objects. The patient can only intermittently control the normal position of the eye. With age, the accommodation and convergence ability of the eye weaken, and the number and time of intermittent exotropia gradually increase, resulting in constant exotropia.

Intermittent exotropia is clinically divided into basic type, over-separation type, pseudo-over-separation type, and insufficient convergence type. It is mainly determined according to the difference between the distance and near viewing angles of intermittent exotropia.
