Amblyopia is commonly referred to as lazy eye. A lack of coordination between the two eyes causes this condition. As each eye receives a different picture, the brain ignores or suppresses the image from the other weaker eye in order to compensate. Typically amblyopia is a result of a variety of factors.

Types and causes

  • This is most often caused by refractive error, or having unequal refractive errors in each eye. This is known as anisometropia, where each eye may have different refractive powers. As a result, one eye has a better ability to focus than the other, and the eye that does not focus as well becomes amblyopic. 
  • In addition, there is deprivation amblyopia, in which an external factor such as cataracts or ptosis (droopy eyelid) prevents one of the eyes from seeing clearly causing the brain to favor the other eye.
  • During pregnancy, the fetus can become affected and cause toxic amblyopia.
  • Strabismic amblyopia occurs when the eyes are not aiming in the same visual direction. Consequently, the eye that is off axis is not looking at the target in regard, becomes amblyopic.

The most common causes of amblyopia are either refractive or strabismic.


A child with amblyopia may:

  • Frequently bump into something on a particular side.
  • Experience a large difference between your farsighted and nearsighted vision.
  • Give preference to one side of the body.
  • Have droopy eyelids.
  • Squint a lot or close one eye.
  • Tilt their head to one side.


A typical treatment approach for these is an evaluation assessment so that an accurate diagnosis can be made for the cause of the amblyopia. Historically when an eye doctor determines the cause of amblyopia, the most common treatment approach that has been shared with a number of patients has been patching or blurring the stronger eye with eye drops, which has been done historically for years with varying degrees of success.

The success rate of the treatment for amblyopia varies a lot because it depends on how well the child applies the patch and how often the parent or teacher reminds him or her to do so. Furthermore this form of treatment only addresses the root cause of the amblyopia but stops short of integrating the weaker eye into a binocular (two eye) visual system. The newer methodology for treating amblyopia is called monocular fixation in binocular field (MFBF). This is a holistic treatment where the brain is taught to integrate the weaker eye's input in coordination with the stronger eye. This treatment is considered the gold standard for amblyopia and uses a combination of occlusion (patching or drops) and in office vision therapy.

  • 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.

  • 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.

  • 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!!

  • 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.

  • 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.
