Worth Four Dot

The worth four dot is an essential tool which helps the clinician understand what the patient is able to see from each eye. It is useful to detect if there is double vision or if there is suppression, which means that the brain is ignoring the visual signals from one eye. There are different causes for suppression and the worth four dot helps identify if the brain is paying attention to the signals from both eyes or if one eye is being favored over the other.

How it Works?

The patient wears glasses that have a red filter on the right eye and a green filter on the left eye. The eye doctor holds a special Worth Four Dot flashlight which comes with four circles on it. There is one red circle, two green circles and a white circle. The eye doctor holds this flashlight at various distances and asks the patient, how many dots do you see? What colors are the dots? Based on the patient’s response, the eye doctor gains a greater understanding of different aspects of the person’s visual system and if there is suppression of one eye.

Possible Outcomes

There are different possibilities of what a person who is wearing red and green glasses would see when looking at the Worth Four Dot. These include:
  • Four dots - this is the ideal result because it means that there is proper fusion between both eyes
  • Three green dots - this means that the patient is only seeing out of their left eye that has the green filter on it and they are suppressing the right eye
  • Two red dots - this means that the patient is only seeing out of their right eye which has the red filter on it and the left eye is being suppressed
  • Five dots - this means that there is double vision because in reality there are only four dots, however this person is seeing more than what is being displayed

This gives the eye doctor a lot of useful information of which eye is being favored and which eye is being ignored through suppression. It also is a helpful indication in how to move forward with the best treatment plan which will train the brain to use both eyes most effectively.

Possible Outcomes

Common Questions

Suppression occurs when the brain chooses to favor one eye over the other by ignoring the visual signals from one eye while only paying attention to the other. The purpose of this is to prevent double or blurry vision. This is the brain’s way of coping when the eyes are not properly working together, however with vision therapy, the brain can properly be trained to operate with both eyes.
There are various causes, such as Double vision, When there is a big gap in the prescription for optical correction between the two eyes, and Lazy eye, also known as amblyopia

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.


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.
