What is the difference between exotropia and esotropia




















They include the visual skill areas of eye teaming, eye focusing and eye movement. You can learn more about functional vision problems and how they are detected here.

Strabismus is a condition in which both eyes do not look at the same place at the same time. It occurs when one or both eyes turn in, out, up or down some or all of the time. Amblyopia is the lack of development of clear vision in one or both eyes for reasons other than an eye health problem that cannot be improved with glasses alone.

Strabismus is a severe problem with eye teaming , one of the three visual skill areas that make up functional vision. Because the eyes are pointing at different places, the brain has difficulty combining the images from both eyes into a single, 3D image.

The constant suppression of an image from one eye can lead to the development of amblyopia in that eye. In cases where the images of both eyes are affected, the brain never develops the ability to see clearly with both of the eyes. People apply lazy eye to both strabismus and amblyopia, which is why it is a bad phrase to use. Some people think amblyopia can lead to blindness, which it cannot.

A third misconception is that the amblyopic eye is the 'bad eye. All three types of amblyopia result from suppression of vision in one or both eyes. The difference is in the root cause of the suppression. Refractive amblyopia: Results from an uncorrected high prescription in one or both eyes.

Strabismic amblyopia: Results from a constant eye turn in one eye. They are also common in children who have other systemic chromosomal or neurologic disorders. Both esotropia and exotropia may be congenital present at birth or acquired developed later, during childhood. Esotropia and exotropia can be intermittent or constant. The most noticeable symptom is one or either eye wandering inward or outward.

You or your child's pediatrician may notice that your child's eyes are not straight. At Children's National, we emphasize the need for a pediatrician's vision and ocular alignment screening at regular well-baby visits.

When in doubt, your pediatrician will refer your child to an ophthalmologist for a comprehensive eye evaluation. If there is family history of pediatric eye diseases, we recommend an early comprehensive eye examination. Treatment for esotropia and exotropia aims to ensure proper vision in both eyes and straighten the eyes. Among the treatment options for esotropia are:. Patients with constant strabismus tend to be less symptomatic but not asymptomatic when compared to patients with intermittent strabismus.

Patients with intermittent strabismus may experience more frequent symptoms. These include:. A clue that your child may have amblyopia is if he or she cries or fusses when you cover one eye. Since amblyopia usually occurs in one eye only, many parents and children may be unaware of the condition. Far too many parents don't know they need to take their infants and toddlers in for an early comprehensive vision examination by an optometrist and many children go undiagnosed.

People incorrectly apply the term "lazy eye" to both strabismus and amblyopia, which is why it is a bad phrase to use. Patients are often told that amblyopia can only be treated until a certain age.

This is outdated information. While early intervention is still ideal, it is never too late to treat amblyopia. Another misconception is that the amblyopic eye is the "bad eye. Treatment for strabismus may include eyeglasses, prisms, vision therapy, or eye muscle surgery.

If detected and treated early, strabismus can often be corrected with excellent results.
