Crossed Eyes

Boy with crossed eyes

Crossed eyes, also known as strabismus, refer to a condition in which both eyes do not look at the same place at the same time. Often times they both turn in, but may also turn out.

What Causes Crossed Eyes?

The six muscles attached to each eye, which control how it moves, receive signals from the brain. These signals direct the eye’s movements. In normal circumstances, the eyes work in an organized fashion so that both point in the same direction at the same time. With crossed eyes, however, the muscles around the eyes do not work together because some are weaker than others. This causes the eyes to turn inward or in the opposite direction of each other.

It is important to have proper eye alignment. Misalignment can cause:

  • Double vision
  • Poor depth perception
  • Poor vision in the turned eye
  • Confusion

When the eyes are askew, the brain receives mixed images from each eye. In the beginning, the person may suffer from double vision and misperception. Over time, the brain becomes trained to ignore the image it receives from the weaker eye. But, if left untreated, the person may permanently lose vision in the weaker eye.

Risk factors for crossed eyes include family history, a considerable amount of uncorrected farsightedness and medical conditions like stroke, head injury, Down syndrome and cerebral palsy.

Though crossed eyes can develop in older children and adults, it typically develops in infants and young children by the age of three. Though babies are commonly affected, some experience a condition called false strabismus or pseudostrabismus, in which their eyes may appear misaligned, but they in fact are aiming at the same direction. This appearance of crossed eyes can be due to having excess skin over the inner corner of the eyes, or a wide bridge of the nose. As the child'face grows, the appearance of crossed eyes diminishes.

Ways to Treat Crossed Eyes

If the child does truly have crossed eyes, it is vital that he or she get treated. While some believe that the condition can be outgrown, it cannot. Crossed eyes can worsen without treatment. If you are the parent of a child who is older than four months and notice that his or her eyes do not appear to be straight at all times, an examination is in order.

In order to diagnose crossed eyes, a comprehensive eye exam will be performed, and it will concentrate on how the eyes focus and move. This may consist of:

  • Visual acuity – reading letters on near and distance reading charts in order to measure and evaluate the degree to which vision is impacted
  • A review of the patient’s family history
  • Refraction – an instrument known as a phoropter is used to conclude the right lens power needed to rectify refractive errors like astigmatism, nearsightedness and farsightedness. During the test, a series of lenses are placed in front of the patient’s eyes while a handheld lighted instrument (retinoscope) gauges how they focus light.
  • Focusing and alignment testing to determine how well your eyes move, focus and work in unison.
  • An eye health examination to observe the internal and external structures of the eyes.

The information rendered from these tests will allow your optometrist to develop a treatment plan, which can involve prisms, vision therapy, eyeglasses or eye muscle surgery. If the condition is found and treated early, it can often be corrected with excellent outcomes.

  • of the best, most thorough, articulate, accessible doctors I’ve ever seen. Her office is packed full of state of the art cool eye tools that provide incredible insight (oops... pun actually works) and she explains so that this non-medical patient can understand. This exam was most comprehensive. One of my eye doctors is a friend and even when visiting him in Santa Monica office, the time Dr Joyce spent with me was comparable. I only wish she had more specialties (e.g. dermatology, podiatry). I’m a patient now so I feel safe. You better call for an appointment now lest she stops taking new patients. Thank you, Dr Joyce!

  • This was my first time at Eyecare For You. The facility was very clean and the office staff pleasant. The young man who I was with in the beginning to do the initial check in process was very efficient, professional and it was very evident that he took his job seriously. I especially liked that he cleaned off each piece of equipment prior to my resting my chin and forehead on them. Dr Joyce was also very professional and personable. Her work ethic was spot on, and she explained each process very clearly and made sure I understood before she moved on to the next section. The equipment seemed to be the most current and I was overall very impressed with the care I received here. I will be returning.

  • Excellent experience with Dr Joyce and others on the staff. No need to get records transferred from previous eye care center. Eyecare For You appears to have the latest hi-tech testing equipment and will determine the best option(s) to improve your vision to its maximum capability. I expect my new prescription glasses with anti-glare coating will minimize glare at night and should allow me to see better than ever. Cost was very reasonable. I have already recommended two friends to call for an appointment ASAP.
