Esotropia or crossed eyes

Approximately 13 million Americans suffer from strabismus, which affects approximately 4% of the population.

Esotropia, commonly called crossed eyes, is a condition that affects 1-2 percent of the population whereby a person uses only one eye to look at objects while the other eye turns inward. Esotropia is a form of strabismus which is the inability of both eyes to align together to look at an object.

Symptoms of esotropia

Following are the common symptoms of esotropia:

  • You may have blurred or distorted vision due to inward deviation of eyes
  • You may look cross eyed
  • You may develop amblyopia (a condition in which vision is suppressed in one eye)
  • You may find it difficult to focus at an object that is nearby or at distance
  • You may find yourself reading or viewing an object with just one eye

Why do we need both of our eyes for great vision?

Esotropia or crossed eyes is not just a cosmetic issue, it deeply impacts many aspects of a person's life by disturbing their binocular vision. Binocular vision is the term that refers to the use of both of our eyes together to see the world. For a person with esotropia things that require both eyes working as a team become much more difficult. For example when we read, use a phone, drive a car, ride a bicycle, walk down the street, or play sports we use binocular vision to perform these tasks. When a functional optometrist works with an esotropic patient, the goal is to restore binocular vision.

Dr. Eric T. Ikeda

Dr. Ikeda, FCOVD, DPNAP, is a leading optometrist in the field of neuro optometric rehabilitation and developmental optometry. He has made profound contributions to the field over the years and uses these expertise to provide the highest quality of eye care to his patients. He was Past-President of the Optometric Extension Program Foundation (OEPF) and of the Neuro-Optometric Rehabilitation Association (NORA). He received the “Founding Fathers Medal” for his continued service to NORA and he was recognized as “Physician of the Year” by the Rehabilitation Nurses Society. He is a clinical associate professor of the Western University of Health Sciences College of Optometry and was inducted as a Distinguished Practitioner into the National Academies of Practice (Optometry Academy).

What causes esotropia?

Our eye movements are controlled by extraocular muscles. These muscles keep our eyes aligned when we are looking at an object. If there is a problem with these muscles it may result in different types of eye misalignments such as esotropia.
A patient's family history may also contribute to this condition. Approximately 30% of children with strabismus have a family member with the same condition.
Esotropia can also be caused by:

  • Refractive errors such as farsightedness
  • Poor vision in one eye
  • Head injuries
  • Neurological issues such as down syndrome, cerebral palsy, hydrocephalus, brain tumors
  • Certain systemic diseases, like hyperthyroidism or diabetes

How is esotropia treated?

Esotropia must be detected and treated early in order to be effectively treated. During the early stages of development, the child's brain is adaptive and has a high chance of responding well to treatment. The good news is that there are effective treatments for esotropia for patients of all ages. Treatment of esotropia is determined on a case by case basis, where the functional optometrist will assess the underlying causes of the esotropia and the ideal treatment for that patient.

Treatment for esotropia involves treating the underlying cause, which may include:

  • Double vision
  • Weak extraocular muscles (responsible for eye movements)
  • Farsightedness (hyperopia)
  • Amblyopia (lazy eye)
  • Binocular vision dysfunction

Vision therapy: Vision therapy has been shown to be an effective, permanent, and non-invasive way to treat esotropia. The goal of vision therapy is to train the brain to use both eyes in tandem to achieve great vision. Vision therapy for esotropia is often done in combination with special prism lenses. The therapy is done in office under the guidance of the functional optometrist and a vision therapist. The in office sessions follow a series of repeated exercises,tailored to the patient's visual deficits and progress. You can schedule an eye exam for vision therapy with our developmental optometrist by calling (562) 925-6591.

Patching is another treatment option especially in patients with acquired esotropia caused by amblyopia. This option forces the brain to utilize the eye that has been ignored. For best results patching should be done in combination with vision therapy in order to promote binocular vision once the amblyopic eye is being used.

Surgery may be performed on your extraocular muscles to fix the misalignment of your eyes. It is performed by an ophthalmologist which may be recommended by our optometrist if necessary. Ideally surgery is done in combination with vision therapy, which allows for the combination of fixing the muscle alignment while reintegrating binocular vision for the patient through therapy.

With eyeglasses, accommodative esotropia can be treated by reducing focusing effort and convergence of the eyes.

Eyeglasses with prisms may also be prescribed to correct the misalignment of the eyes, effectively correcting esotropia.

Types of esotropia

Intermittent esotropia

This type of esotropia does not cause eye deviation constantly. If a person has this type of esotropia, their eyes may deviate inward after doing near work for a long time.

Infantile esotropia

Infantile esotropia usually manifests within the first six to twelve months of life. Most children develop controlled eye movements before the age of 6 months, but they don't have them during the first few months of life. Esotropia in infants is evident by a large angle deviation. It is also associated with latent nystagmus.

Accommodative esotropia

Typically, this type of esotropia develops between 1 and 4 years of age. Initially, it is intermittent, but over time it becomes more frequent. It usually occurs in children who are more farsighted than usual. Their eyes have to work harder to see clearly when viewing an object that is up close. Due to this excess effort, the eyes become over-converged or crossed.

Acquired esotropia

Unlike esotropia that develops earlier in life, acquired esotropia develops later in life. It could be due to untreated hyperopia (inability to close up objects clearly), double vision, lazy eye (amblyopia) or diabetes.

Sensory esotropia

This type of esotropia occurs in children less than 4 years old. A child with impaired vision in one eye is most likely to suffer from this condition. To get clear vision, our brain must fuse images from both eyes. When one eye does not have good vision, it drifts inwards causing esotropia.

Esotropia is a form of strabismus in which one eye drifts inwards towards the nose while looking at an object that is closeby or at distance. There are many types of esotropia, which can be caused by double vision, amblyopia, hyperopia, weak extraocular muscles, or neurological conditions. Depending on the underlying cause, esotropia may be treated with eyeglasses, patching, vision therapy, surgery, and prisms. A vision therapy program can provide lasting effects and reduce the symptoms of esotropia and is often combined with other treatment options such as surgery or patching for better results. No matter how big or small your esotropia angle is, we can help you manage it and deal with it. You can schedule an eye exam for vision therapy (also called a functional or developmental eye exam) with our functional optometrist at Amplify EyeCare of Greater Long Beach by calling (562) 925-6591. Patients with eye alignment issues such as esotropia visit our clinic from all over California, and we are proud to be a leading provider of vision therapy services for patients from Bellflower, Long Beach, Lakewood, and Los Angeles.


I haven't actually used the optometrist side, so my review is limited to the vision therapy offered.  This office was recommended by my occupational therapist for the treatment of my double vision following a stroke.

Claire A.

Love this location. I had a brain injury accident from day one one. All the team make you feel you still important and hope in the horizon after when the medical system fell you miserably. Dr. Ikeda very professional and very understanding about your issue. Two tombs up.

Jim K.

My husband and I were immediately impressed with Dr Ikeda. I was hit by a car while cycling which caused broken bones and three brain injuries. The brain injuries caused double vision. Dr. Ikeda examined my eyes and got me started on vision therapy with his occupational therapist who specializes in vision therapy.  She (Chris) is absolutely great.  I am impressed with the array of tools used to help recover my binocular vision.  I am doing things I never thought were possible (balance boards etc).  Chris pushes me and keeps me motivated. I really enjoy my sessions with her.  The office staff is always friendly and they have a wonderful appointment reminder tool that makes it easy to keep my calendar up to date. I am happy the rehab center at Little Co. of Mary recommended them!!

Teresa S.

The Vision Therapy is handled in a separate office through a different door from the shared waiting room. Chris, the vision therapist, has a wide and varied assortment of tools, equipment and resources to best evaluate and treat most vision issues. After just a few visits, my double vision became easier to control, using exercises developed during the therapy process. It was time well-spent.

Joe M.

I have been coming here since I can remember. I love it here. The staff is so amazing and nice. They explain everything they gonna do and never make you feel rushed. Dr. Ikeda has always been my doctor and I would never want another one. He is the doctor for my whole family and is always asking how everyone is doing. I am also so crazy about picking out my frames and have to try so many and each person who helps me take the time and lets me try them all on. I would never want to go anywhere else! I definitely would recommend this office to anyone looking for a great eye doctor.

Kayla W.

This is not for the eye exam but for the frames selection portion. I brought my prescription from Kaiser here with my VSP insurance. The reception staff was very polite and professional.  Manny helped me to pick out frames and explain my coverage.  Very helpful and patient not like the individual at the other place I rated here on Yelp.  I was running late and he still helped me and was not bothered at all.  I am so glad I came here ..........very pleased.

Very professional staff and pleasant.
