An Alternative to Patching

If one eye is weaker than the other, such as in the case of a lazy eye, one method that is used to train the brain to work with both eyes in an optimal manner is patching. This means the stronger eye is closed with a patch, forcing the brain to learn to work with the weaker eye. This method presents advantages and disadvantages. The main challenge with this approach is the fact that we shut down the functionality of the stronger eye for a period of time with the goal of strengthening the weaker eye. This could compromise the stronger eye since it doesn’t get used for some time. Once we stop using the patch, then the brain needs to relearn how to use both eyes together simultaneously which could present a challenge.

 

Monocular Fixation in a Binocular Field

There is a wonderful alternative to patching and that is monocular fixation in a binocular field, in short MFBF. This allows both eyes to be open while training and strengthening only one eye at a time, avoiding the need to shut one eye off. In order to achieve the MFBF effect, filters are used. For example, during a vision therapy session, a child is given the task of completing a maze on a paper by tracing the right path to the way out using a red marker. In that case, we would place a green filter in front of the lazy eye or weaker eye that we are working to strengthen. Since there’s a green filter in front of the eye, this specific eye is still able to view the target and perform the task of completing the maze. The other stronger eye which does not require training at the moment, is open however there is a red filter placed on top which prevents this eye from seeing the target. It means that both eyes are open but the weaker eye must meet the challenge to complete the task all on its own. By keeping both eyes open but using filters, we can control which eye is receiving the strength training and which visual signals the brain is able to perceive.

Common Questions

Yes, there is an alternative to closing one eye with a patch for a period of time. The alternative method allows both eyes to stay open while using filters to control which eye is actively being trained. This avoids the challenges that come with keeping one eye shut for a period of time. Using filters to strengthen the weaker eye while the stronger eye is open but not participating in the activit, is called monocular fixation in a binocular field.
MFBF stands for monocular fixation in a binocular field. This means that one eye is being trained to properly fixate while the other eye is open but not participating in the activity. This provides many advantages as it enables one eye to be trained at a time, without the need to completely shut off the alternate eye. The other eye can remain opened but using filters it is separated so that it won’t interfere with the training of the eye that is currently being strengthened.

Summary

There are various methods available nowadays which allow one eye to participate in a vision therapy activity at a time. Patching closes off the stronger eye, forcing the brain to learn how to work properly with the weaker eye. The alternative method of MFBF employs filters to keep both eyes open but to enable the focus to be on one eye at a time.

Testimonials


  • 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.
