Parent question: What is Strabismus?

Understanding the Causes and Treatment Options of Strabismus

As parents, we want our children to have healthy eyesight, but sometimes things don’t go as planned. One of the most common eye conditions in children is strabismus, which affects up to 4% of all children. In this article, we will explain what causes strabismus, how to detect it, and what treatment options are available.

What is Strabismus?

Strabismus is a condition in which the eyes are misaligned and do not work together to look at the same object. Depending on the type of strabismus, one eye may turn in, out, up, or down, while the other eye stays straight. Strabismus can be constant or intermittent, and can affect one or both eyes.

What Causes Strabismus?

There are several factors that can contribute to the development of strabismus. Some of the most common ones are:

  • Congenital (present at birth) or acquired (developed later) abnormalities in the eye muscles or nerves that control them.
  • Refractive errors (e.g. nearsightedness, farsightedness, or astigmatism) that are not corrected with glasses or contacts.
  • Other eye conditions or diseases, such as cataracts, retinopathy, or amblyopia (lazy eye).
  • Neurological conditions, such as cerebral palsy, Down syndrome, or brain tumors.

In many cases, the exact cause of strabismus is not known, but it is believed to involve a combination of genetic, environmental, and developmental factors.

How is Strabismus Detected?

If you suspect that your child has strabismus, it is important to schedule an eye exam with an ophthalmologist or optometrist. They will perform a series of tests to evaluate your child’s visual acuity, eye alignment, and eye movements. Some of the tests may include:

  • Visual acuity test: measuring how well your child can see at different distances.
  • Cover test: observing how the eyes work together when one eye is covered and then uncovered.
  • Retinoscopy: shining a light into the eye to assess the refractive error.
  • Ophthalmoscopy: examining the inside of the eye with a special lens.

What are the Treatment Options for Strabismus?

The goal of strabismus treatment is to improve eye alignment, visual acuity, and depth perception, as well as to prevent complications such as amblyopia or double vision. The treatment options depend on the type and severity of the strabismus, as well as the age and overall health of the child. Some of the most common treatment options are:

  • Eyeglasses or contacts: correcting refractive errors can help reduce the strain on the eye muscles and improve eye alignment.
  • Patching or blurring therapy: covering or blurring the stronger eye to stimulate the weaker eye can help improve its function and reduce the dominance of the stronger eye.
  • Vision therapy: a series of eye exercises and activities that aim to improve eye coordination, tracking, and focusing skills.
  • Prism glasses: special glasses with prism lenses that can help bend light and align the images seen by both eyes.
  • Surgery: a procedure in which the eye muscles are repositioned or adjusted to improve alignment.

The choice of treatment depends on many factors, such as the severity of the strabismus, the age and cooperation of the child, the presence of other eye conditions, and the preferences of the parents and doctors.
