What is meant by Exodeviation?
ex·o·pho·ri·a. (eks’ō-fōr’ē-ă) Tendency of the eyes to deviate outward when fusion is suspended.
What causes exotropia?
Causes of exotropia Exotropia occurs when there’s an imbalance in eye muscles or when there’s a signaling issue between the brain and eye. Sometimes a health condition, like cataracts or stroke, can cause this to occur. The condition may also be inherited.
What is exotropia eyes?
Exotropia—or an outward turning of the eyes—is a common type of strabismus accounting for up to 25 percent of all ocular misalignment in early childhood. Transient intermittent exotropia is sometimes seen in the first 4 – 6 weeks of life and, if mild, can resolve spontaneously by 6 – 8 weeks of age.
Can you see with exotropia?
Symptoms associated with an intermittent exotropia can be double vision, squinting in the bright sunlight, covering/closing an eye, blurry vision, poor reading fluency, etc. Alternating exotropia: An alternating exotropia is an outward eye turn that can alternate which eye deviates.
What does exotropia look like?
Exotropia is a form of strabismus where the eyes are deviated outward. It is the opposite of esotropia and usually involves more severe axis deviation than exophoria. People with exotropia often experience crossed diplopia….

Will glasses help exotropia?
Intermittent exotropia is one of the most common types of eye misalignment in children. Intermittent exotropia is often treated using glasses with special lenses (overminus glasses). These glasses are like those prescribed for near-sighted people. These glasses make the eyes work harder in order to see clearly.
Can a child outgrow anisometropia?
The final visual result depends greatly on a child’s age, whether appropriate treatment is followed, and how the glasses prescription changes over time. Some children may outgrow their need for glasses/contact(s), while many will likely have an ongoing need for glasses.
When should anisometropia be corrected?
Ideally, you should examine the child by 6 months of age and then at 24 months if the child is non-symptomatic. If you note a high refractive error or anisometropia, begin treatment promptly.
What is the meaning of the word exodeviation?
(ek’so-fō’rē-ă), Do not confuse this word with esophoria. Tendency of the eyes to deviate outward when fusion is suspended. Synonym(s): exodeviation (1) [exo- + G. phora, a carrying] Tendency of the eyes to deviate outward when fusion is suspended. [exo- + G. phora, a carrying]
When does exodeviation tend to be a major complaint?
If the magnitude of the exodeviation is greater than that of the DVD, DHD will tend to be the major complaint. DHD, like DVD, may occur in patients with LN/MLN due to primary infantile microtropias, but the typical patient has a secondary microtropia (usually eso but sometimes exo) after surgical correction of larger angle infantile strabismus.
When does an exodeviation of the eye occur?
This is an exodeviation (often constant) with an onset in the first six months of life which does not resolve. There is an increased incidence with cerebral palsy and other neurologic disorders, craniofacial disorders, and ocular albinism. A blind or poorly seeing eye may drift outward.
How is exodeviation related to sensory exotropia?
Although they are considered as comitant deviations, they may develop incomitance from secondary changes in the lateral rectus muscles in long-standing cases, especially in sensory exotropia or infantile exotropia with a large deviation, or where the exodeviation is due to amblyopia or structural abnormalities in the misaligned eye.
