It is the opposite of esotropia and usually involves more severe axis deviation than exophoria. People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence of poor vision in one eye.
Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance. It is a type of heterophoria. Cause
This condition can be esophoria, where the eyes tend to cross inward in the absence of fusion; exophoria, in which they diverge; hyperphoria, in which one eye points up or down relative to the other; or cyclophoria, in which one eye is rotated differently around its line of sight from that of the other.
Convergence insufficiency is a binocular vision disorder that affects the ability of the eyes to turn towards each other. It can cause symptoms such as double vision, eye strain, headache, and difficulty reading. Learn about the diagnosis, treatment, and prevalence of convergence insufficiency.
Esotropia (from Greek eso 'inward' and trope 'a turning' [1]) is a form of strabismus in which one or both eyes turn inward. The condition can be constantly present, or occur intermittently, and can give the affected individual a "cross-eyed" appearance. [2]
Exophoria is a tendency of the eyes to deviate outward, usually mild and with fusion possible. It can be caused by refractive errors, divergence excess, or convergence insufficiency, and is common in infancy and childhood.
Dry eye syndrome, also known as keratoconjunctivitis sicca, is a condition of having dry eyes that can affect vision and eye health. Learn about the causes, such as age, contact lenses, medications, and meibomian gland dysfunction, and the treatments, such as artificial tears, eye drops, and surgery.
A rare eye movement disorder caused by a unilateral lesion of the brainstem or cranial nerve VI. It affects the ability to move the eyes horizontally and adduct them, and may be associated with nystagmus and convergence sparing.
