Ophthalmology. Esotropia 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. [1] It is the opposite of exotropia and usually involves more severe axis deviation than esophoria.
The nerve dysfunction induces esotropia, a convergent squint on distance fixation. On near fixation the affected individual may have only a latent deviation and be able to maintain binocularity or have an esotropia of a smaller size.
Acquired non-accommodative strabismus and secondary strabismus are developed after normal binocular vision has developed. In adults with previously normal alignment, the onset of strabismus usually results in double vision. A child with accommodative esotropia affecting the right eye
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. Intermittent exotropia is a fairly common condition.
Strabismus surgery (also: extraocular muscle surgery, eye muscle surgery, or eye alignment surgery) is surgery on the extraocular muscles to correct strabismus, the misalignment of the eyes. [1] Strabismus surgery is a one-day procedure that is usually performed under general anesthesia most commonly by either a neuro- or pediatric ...
Esotropia. In a patient with an unsuppressed esotropia, the patient will see two lights with one line through each light. The line corresponding to the right eye will be on the right side, meaning the images are uncrossed. Exotropia
Botulinum toxin injection is commonly used for small and moderate degrees of infantile esotropia, acquired adult strabismus, and where it is a consequence of retinal detachment surgery, that is, in cases where there is good potential for binocular vision, so that the corrected alignment can be stabilized by motor fusion.
Esophoria. Specialty. Ophthalmology. Esophoria is an eye condition involving inward deviation of the eye, usually due to extra-ocular muscle imbalance. It is a type of heterophoria .
Causes. Anisometropia is caused by common refractive errors, such as astigmatism, far-sightedness, and myopia, in one eye. [6] Anisometropia is likely the result of both genetic and environmental influences. [7] Some studies suggest, in older adults, developing asymmetric cataracts may cause worsen anisometropia.
It is considered particularly useful for patients who have the potential for binocular vision; success rates are higher for treating postoperative esotropia than for treating postoperative exotropia.
