Intermittent exotropia is the most common form of strabismus, characterized by an intermittent outward deviation of the eyes, affecting as much as 1% of the population. 1,2 This condition most often presents in childhood and affects females more than males.
This topic will focus specifically on intermittent exotropia, which is the most common type of manifest exodeviation. Disease Intermittent exotropia comprises about 75-90% of the cases of exotropia and is usually preceded by a stage of exophoria.
Intermittent exotropia is the most common form of exotropia. It may affect about 1% of the population. Intermittent exotropia is not present all the time. Your eye may turn outward when you’re tired, sick or under stress. It is typically more noticeable when looking far away or daydreaming.
Intermittent exotropia is the most common type of strabismus. It is defined as a non-constant exodeviation that manifests predominantly at distance fixation and may progress over a variable period to near fixation.
Intermittent exotropia is an exodeviation intermittently controlled by fusional mechanisms. Unlike a pure phoria, intermittent exotropia spontaneously breaks down into a manifest exotropia. Prevalence - Exodeviations are much more common in latent or intermittent form than are esodeviations.
Intermittent exotropia is a very common type of eye misalignment. One or both eyes turn out toward the ear occasionally. Only one eye turns out at a time while the other eye points straight forward. Cause of intermittent exotropia. The cause of this condition is not known.
Intermittent exotropia may occur in infants as young as 1 to 2 months of age. If the condition is mild, it may go away on its own within 6 to 8 weeks of birth. In other cases of exotropia, it is not common to find a complete resolution of the condition. Patching, glasses, or vision therapy can help.
Intermittent exotropia (X (T)) is characterized by an intermittent outward deviation of one eye, and is the most common form of strabismus, affecting approximately two out of 100 children before the age of 3 years [1]. Treatment of X (T) includes occlusion, use of overminus lens, and surgery [2].
Intermittent exotropia (X (T)), the most common form of divergent strabismus, is seen in 60–70% of normal infants, is transient, and usually resolves in the first few months of life as the attention required to maintain binocularity improves [1]. Small exophorias are found in high frequency in adults.
Dr. Katherine Lee reviews her current management strategies for intermittent exotropia (IXT) in light of recent Pediatric Eye Disease Investigator Group (PEDIG) studies.
