Strabismus (Crossed Eyes) Treatment in Children

Strabismus — when a child's eyes don't point in the same direction — affects about 3 to 4 percent of children. Treatment depends on type but often includes glasses, patching the stronger eye, vision therapy, or surgery. Early intervention is important to preserve vision in both eyes before the visual system matures.

What is strabismus and why does it matter?

Strabismus means the eyes are misaligned — one or both eyes turn inward (esotropia), outward (exotropia), upward, or downward instead of pointing together at the same object. The turning may be constant or intermittent, and it may affect one eye consistently or alternate between eyes.

Beyond its effect on appearance, strabismus has an important impact on visual development. When the brain receives two misaligned images, it learns to suppress (ignore) the image from the turned eye to avoid confusion. Over time, this suppression can cause the turned eye to develop permanently reduced vision — a condition called amblyopia (sometimes called lazy eye). Amblyopia becomes increasingly difficult to treat as the visual system matures, which is why early identification and treatment of strabismus matter 12.

How is strabismus detected?

A Hirschberg test (light reflex), cover-uncover test, and alternate cover test during a pediatric eye exam can detect eye misalignment — even when parents are not certain they see it consistently. Vision screening is recommended beginning at six months of age and at well-child visits throughout childhood 23.

If a pediatrician or optometrist suspects strabismus, the next step is a comprehensive evaluation by a pediatric ophthalmologist — a physician who specializes in children's eye conditions and strabismus surgery. This evaluation involves dilated refraction (measuring the prescription under drops that relax the focusing muscles) and a detailed assessment of the eye movement pattern.

What are the treatment options?

Treatment depends on the type, severity, and underlying cause of the misalignment:

Glasses Many children with esotropia (eyes turning inward) have significant farsightedness. The eyes cross inward as they strain to focus. Providing the correct glasses prescription reduces the focusing effort and can fully or partially correct the inward turn without surgery. This is called accommodative esotropia, and glasses are often the primary treatment 1.

Patching or atropine drops (for amblyopia) If one eye has developed amblyopia from suppression, the stronger eye is temporarily blurred — either with a physical patch worn for prescribed hours each day, or with atropine drops that blur near vision — to encourage the weaker eye to work harder. This does not correct the alignment itself but is critical for developing vision in the amblyopic eye 12.

Vision therapy For intermittent exotropia (eyes turning outward occasionally) and some forms of convergence insufficiency, a structured program of visual exercises — done in an optometrist's or orthoptist's office and at home — can improve eye teaming and reduce the frequency of the outward turn. It is not the primary treatment for all strabismus types.

Surgery When non-surgical measures do not achieve adequate alignment — or for types of strabismus where glasses alone are insufficient — strabismus surgery is performed to reposition the muscles that control eye movement. Surgery adjusts the tension in one or more of the six extraocular muscles to bring the eyes into better alignment. It is typically done under general anesthesia as a same-day outpatient procedure.

Surgery does not replace the need for glasses if the child is significantly farsighted; many children need to continue wearing glasses after surgery to maintain alignment 1.

Is surgery safe, and what does recovery look like?

Strabismus surgery is among the most commonly performed pediatric surgical procedures and has a well-established safety profile. The eyes are red and sore for a week or so afterward, and children typically return to school within a few days.

More than one surgery is sometimes needed to achieve the desired alignment — this is not a failure of the first procedure, but rather a reflection of the complexity of achieving precise binocular alignment. The surgeon will discuss expectations for your child's situation specifically 1.

How urgent is evaluation?

Early evaluation matters because the visual system is most plastic (responsive to treatment) in the first several years of life. Amblyopia is most effectively treated before age 7, though treatment in older children and even adults can sometimes yield improvement.

If you notice your child's eye crossing, wandering, or not appearing aligned — especially if it is constant rather than occasional — a pediatric ophthalmology evaluation is appropriate. For infants, persistent eye crossing after three months of age should prompt evaluation, since occasional crossing before this age is normal as the visual system matures.

Common questions

What is the difference between strabismus and amblyopia?

Strabismus is the misalignment of the eyes. Amblyopia (lazy eye) is the reduced vision in one eye that can result from the brain suppressing that eye's image. They often occur together, but amblyopia can also develop from a different cause (such as a large difference in prescription between the eyes), and strabismus does not always cause amblyopia.

Will my child outgrow crossed eyes?

Intermittent outward drifting in the first few months of life sometimes resolves spontaneously. Persistent or inward crossing (esotropia) does not outgrow — it requires evaluation and treatment. Do not delay seeking assessment in the hope that alignment will self-correct, as vision development is at stake.

How long does my child need to wear the patch?

Patching duration depends on the severity of amblyopia and the child's response. Your child's ophthalmologist will prescribe a specific number of hours per day and monitor progress with regular vision checks. Patching is usually continued until vision is equal or maximally improved — often months.

Can strabismus surgery give my child perfect alignment?

The goal is functional alignment — eyes that work together well enough to support binocular vision and a normal appearance. Perfect alignment in all gaze positions is not always achievable, and outcomes are discussed in detail before surgery. Many children achieve excellent results from a single procedure.

When to seek evaluation promptly

  • —Eye crossing that is constant rather than intermittent, at any age
  • —New or sudden onset of eye turning in a child who previously had straight eyes — this can occasionally signal a neurological issue
  • —Infant crossing that persists past 3 to 4 months of age
  • —Head tilt or turning to one side to see clearly
  • —One eye that appears to have reduced vision or does not track normally

Sudden new eye deviation in a child with no prior strabismus warrants same-day or next-day evaluation, as it can rarely be a sign of elevated intracranial pressure or a cranial nerve palsy. Go to an emergency room if accompanied by vomiting, headache, or altered consciousness.
