Strabismus Causes and Treatment

man with lazy eye

In order for your eyes to focus normally, six muscles around each eye must work together. When your two eyes see different images, your brain tends to favor the stronger eye. This means the weak eye gets weaker, resulting in amblyopia, or “lazy eye.”

Risk factors for developing strabismus may include farsightedness and a family history of the disorder. Both adults and children suffer from strabismus, but the causes are different. For adults, causes include:

  • Diabetes
  • Stroke
  • Botulism
  • Graves’ disease
  • Shellfish poisoning
  • Guillain-Barré syndrome
  • Cranial nerve palsies
  • Tumors
  • Eye injuries
  • Traumatic brain injury
  • Vision loss

Treatment

Treatment for strabismus involves a few steps. First, your eye doctor will determine whether you need glasses. Then, he or she will treat your amblyopia. This typically involves wearing a patch over the stronger eye, forcing the weak eye to work harder. This can be frustrating and tiring, but is an important step.

Next, you might need surgery to help the eye muscles work together correctly. This surgery can be done at any age. Eye alignment surgery is generally performed as an outpatient procedure, often with local or regional anesthetic. However, in some cases, it might require hospitalization. Most people can return to their regular activities within a few days. Your doctor might restrict swimming and heavy lifting for several weeks.

The reasons to have eye alignment surgery go way beyond cosmetic benefits. Eye misalignment can cause disabling and dangerous double vision. Since people with strabismus are often self-conscious about this condition, getting alignment surgery may improve your circumstances emotionally, socially and even economically.

What to Expect After Treatment

Any type of surgery bears risks, including infection, bleeding and anesthetic complications. The most common risks for strabismus surgery are double vision and residual misalignment. In rare cases, patients may suffer retinal detachment or decreased vision. However, most patients experience a significant improvement in eye alignment after surgery. They may feel pain and a pulling sensation around the eyes for a few days. Usually over-the-counter pain relievers can address this level of discomfort.

  • "Dr. Casas and her staff are so patient and friendly. Dr. Casas prescribed glasses and I had the toughest time picking out frames. They didn’t rush me, but instead made helpful suggestions and now I have an awesome pair of frames, not to mention the fact that I can see ten times better than before. You guys are the best!"
  • "I’ve been going to Dr. Casas for over five years now and even though I only see him once a year for my annual exam, he and his staff always make me feel very welcome and take care of all my eye care needs. Dr. Casas and Associates is the best at what they do and make you feel right at home."
  • "I was having headaches and felt my contacts were easily drying out all the time. I went in to see Dr. Casas and after an evaluation, he suggested a switch in the type of lenses I use. Within a week of using the new lenses, I noticed a change and haven’t had any problems since. Thanks, Dr. Casas!"
  • "I had considered Lasik surgery in the past, but was still hesitant about the process. Dr. Casas was very thorough in her consultation with me and answered all of my questions, making me feel comfortable with going forward with the procedure. I’m so glad I did the Lasik, it has been of great convenience to me and my sight has never been better"
