Many types of strabismus can develop in children or adults, but the two most common forms are: 1  Accommodative esotropia often occurs because of uncorrected farsightedness (hyperopia). 2  Intermittent exotropia may develop when a person cannot coordinate both eyes together.

Your eyes are not deceiving you: Newborn eyes are commonly crossed or at least appear that way. That's because some babies are born with extra folds of skin in the inner corners of their eyes, giving them a cross-eyed appearance. As babies grow, the folds disappear — as does that cross-eyed look.

Normally, the eyes work together so they both point at the same place. When problems develop with eye movement control, an eye may turn in, out, up or down. The eye turning may occur all the time or may appear only when the person is tired, ill, or has done a lot of reading or close work. In some cases, the same eye may turn each time.

Testing for strabismus, with special emphasis on how the eyes focus and move, may include: : 1  Patient history. An optometrist will ask the patient or parent about any current symptoms. 2  Visual Acuity. An optometrist will measure visual acuity to assess how much vision is being affected. 3  Refraction.

Many types of strabismus can develop in children or adults, but the two most common forms are: 1  Accommodative esotropia often occurs because of uncorrected farsightedness (hyperopia). The eye's focusing system is linked to the system that controls where the eyes point.

Crossed eyes, or strabismus, is a condition in which both eyes do not look at the same place at the same time. It usually occurs in people who have poor eye muscle control or are very farsighted. Six muscles attach to each eye to control how it moves.

An optometrist should examine any child older than 4 months whose eyes do not appear to be straight all the time. Strabismus is classified by the direction the eye turns: Inward turning is called esotropia. Outward turning is called exotropia. Upward turning is called hypertropia. Downward turning is called hypotropia.

Do a home eye test. Shine a (not-too-bright) light into your baby's eyes and notice the light reflect (the tiny white dot that shows in the middle of each eye). When your baby is looking directly at the light, the light reflects should be in the center of each eye. This indicates that the eyes are straight. The tiny white dot should remain in the center of the eye as you move the light from side to side and around in a circle as your baby follows it. If, however, you notice that the white dot is in the center of one eye and off to either side of the other eye, your baby's eyes may be crossed. It's common for a baby's eyes to occasionally appear crossed when baby is particularly tired, but it's still important to mention what you noticed to your pediatrician at your baby's next scheduled checkup.

This is a condition called pseudostrabismus or false strabismus. The appearance of crossed eyes may be due to extra skin that covers the inner corner of the eyes or a wide bridge of the nose. Usually, the appearance of crossed eyes will go away as the baby's face begins to grow. Strabismus usually develops in infants and young children, most often by age 3. But older children and adults can also develop the condition. People often believe that a child with strabismus will outgrow the condition.

Most babies outgrow this problem by the time they are a few months old. Babies whose eye alignments do not improve by 3 or 4 months of age should see an ophthalmologist who is trained in caring for infants. Sometimes the shapes of the eyes can make it look like a baby's eyes are crossing so if you're not sure, have your pediatrician check it out. It can be helpful to take a picture of your baby's eyes when they do not appear to be aligned so the doctor can see the suspected problem in action. ...
