What are the symptoms? continued...
An older child may also complain about blurred vision, tired eyes, sensitivity to light, or double vision.
Symptoms may come and go. They may get worse when your child is tired or sick.
A newborn's eyes may be misaligned at first. But the eyes should become aligned by 3 to 4 months of age. In some cases, the eyes may simply seem to be misaligned because the child has a wide bridge of the nose that creates the appearance of crossed eyes. But if your child's eyes aren't aligned all of the time after age 4 months, take your child to the doctor for an eye exam.
How is strabismus diagnosed?
A doctor can often tell that a child has strabismus just by looking at the child's eyes. It may be obvious that the eyes don't look in the same direction at the same time.
The doctor may have the child look at an object while covering and then uncovering each eye. This allows the doctor to see which eye turns, how much it turns, and under what circumstances the abnormal turn occurs. These tests will also help the doctor find out if the child has amblyopia (lazy eye), which sometimes occurs with strabismus.
Most experts suggest that children have an eye exam between the ages of 3 and 5, and earlier in some cases.1 But no child is too young for an eye exam. If you have concerns about your child's eyes or vision at any age, take him or her to an eye doctor.
How is it treated?
The most common treatments for strabismus are:
Glasses. Wearing glasses can sometimes correct mild strabismus.
A temporary eye patch over the stronger eye if your child has amblyopia. This can make the weak eye stronger, which may help align the eyes. Your child may have to wear the patch some or all of the time for a few weeks or months.
Surgery on the eye muscles. This is often the only way to improve vision and better align the eyes. It may take more than one surgery, and your child may still need to wear glasses.
Other treatments may include medicines and eye exercises.
Treatment for strabismus should begin as soon as possible. In general, the younger the child is when treatment begins, the better the chances are of correcting the problem.
It's also important for your child to get follow-up exams.
