Treatment Tools

Meet Duke, an American Pit Bull Terrier. He is going to help us model each treatment lens we use here at Nashville Vision Therapy. Thanks, Duke!

To start us off, Duke is demonstrating his focusing abilities and anticipating a tracking exercises. He gets a little bored of just focusing and following a eyeball, so he decided to show us some fancy treatment tools our office uses during Vision Therapy.


Here we go...




Why is Duke wearing 4 lenses? Great question! These are called accommodative flippers. These lenses are used to improve the flexibility and strength of a patient’s focusing system. We use these with the Hart (letter) Chart, when reading, and when we use a tool called Aperture Rule. There are minus lenses on one side, and plus lenses on the other. The word "flipper" comes in handy because you flip the lenses back and forth while doing certain exercises to improve the focusing system.



Harry Potter is that you? No, it's just Duke wearing prisms! I could go on and on about prisms. We use them all the time, kids think they are so fun!  

"Prisms create total "eye-mind-body” changes and improved perception of depth and space.  Prism produces changes in orientation with corresponding shifts in both eye movement and pelvic positions. They are a valuable tool in breaking down patterns that have developed over time that enable the patient to cope with their visual condition." 

Here is a great article about prisms, which includes examples on how to use prisms in Vision Therapy exercises. Take a look: http://www.oepf.org/sites/default/files/22-5-FOX.pdf.


Duke circa 1970. These red/green (or can use red/blue lenses) lenses help us use both eyes together. Using these red/green lenses, allows us to see if a patient is suppressing the visual input from one eye.

When using these lenses we use a transparent film with red/ green stripes. We place this film over reading materials, hidden pictures, mazes, or letter charts. When doing the exercises you have to use both eyes enable to see the whole image. If you are not using both eyes, parts of the picture will be missing.


Each one of these tools helps the visual system work more efficiently. What do you think? Which lens have you used during therapy, and with what exercises? Have questions? Email us at VT@rdeyes.com.

Work that Peripheral Vision

Hello, readers. Happy Friday! If you remember, last week we talked about peripheral stability. As promised, here are some fun peripheral awareness exercises for home!
 
A couple of weeks ago I discussed building up the vestibular system. One of the exercises I mentioned was reading a letter chart while tossing a beanbag from your right to left hand and back again. This exercise is also great for your peripheral vision! Because you’re reading the letter chart, your central vision will be fixed straight ahead. This means that you will have to rely on your peripheral vision to get the beanbag back and forth. You can also use scarves (or a balloon) in place of beanbags to start, since the beanbags fall faster and will be more difficult.

Thanks to a fellow vision therapist, I have been doing a lot peripheral taps lately! They are a great easy home exercise. They note:

"Peripheral Taps
1.      Place your finger tips near your body facing the student
2.      Without taking their eyes off of you (I put a stick on my nose for children to focus on), have the student tap your fingers with his/her finger tips.
3.      Alternate hands and places around the face.”

Another awesome activity (that works on tracking AND peripheral vision) that I found is described in the following video. This activity would be easy to create at home, and is fun and engaging! Using regular flashlight is just fine.



As Dr. Julie mentioned when children or adults block out peripheral vision which then creates a tunnel vision effect it can cause loss of concentration and/or difficulty driving.

These are fun, easy home exercises to do at home that will greatly improve your peripheral vision. Try them out and let us know how it goes!

Peripheral Stability

Since Autism Awareness month was in April, I have been doing more research on how vision is affected by the diagnosis. As you might remember in this blog,"The goals of treatment may be to help the autistic patient organize visual space and gain peripheral stability so that he or she can better attend to and appreciate central vision and gain more efficient eye coordination and visual information processing."

The main phrase that stood out to me was "peripheral stability." I emailed some fellow Vision Therapist on ways I can incorporate more fun peripheral vision exercises into our treatment.  From there I looked for articles about peripheral vision and found an article by Dr. Gallop, titled "The Peripheral Visual Awareness: The Central Issue". The article had so much great information that I thought I would share a few tidbits that helped me a lot.

"Peripheral vision is the lion’s share of vision and, is also a big part of life. It is involved with detecting and understanding the big picture – the context and changes in our environment. At least visually speaking, it helps to keep us in touch with our relationship to everything with which we share visual space. Peripheral vision is at the heart of awareness of, and response to, the total space volume of our visual environment and all its inhabitants. Without the involvement and guidance of peripheral awareness the fovea would, for the most part, be “lost in space,” not knowing where to turn."

"This may also contribute to attention problems because without sufficient peripheral awareness, the context of visual space is lost and it becomes difficult to distinguish figure from ground. The environment becomes a series of unconnected, unrelated details to be dealt with one at a time – the background is practically non-existent."

"It is important to note that the real importance of peripheral awareness is not in the receiving of information as much as is it is in the response to that information. Knowing what is in our surroundings is important in the context of action for survival. While it is certainly important to know what is going on out there, it is equally important to know what needs to be done and how to go about doing it in response to what is going on out there. Peripheral vision provides an early warning system and is what guides our movements in response."

"Peripheral vision supplies us with information about our relationship to our surroundings. It tells us where we are in relation to people, places and things in our immediate vicinity. It can provide significant information about who they are, what they are doing, and how that may affect us at that moment and in the near future. When functioning comfortably and effectively it can provide accurate information regarding size, shape, direction of movement, and even intent."

"Just as improvements achieved through vision training often transfer into improvements in areas such as problem solving, concentration and self-esteem, improvements in peripheral processing may transfer into more so-called peripheral aspects of our lives."

Our peripheral vision is not something to mess around with. It is an important for our survival! Loved this article! Next week I will gather up some great peripheral vision awareness exercises that you can do at home.

CNN article

One of my favorite news apps on my phone is the CNN app. I like the quick videos, and articles of the current events happening around the world. I will say, the "Distraction" videos on CNN are always a favorite. Like this one:



While reading some articles, I stumbled upon this: Man: 3-D movie changed my sight for the better. It is about a man who "had poor depth perception. His eyes pointed outward and did not allow him to see, in stereo, a single image with both eyes." One day he went to see Hugo in 3-D and "to his amazement, the characters and scenery in this film jumped out at him in greater stereo vision than he had experienced before." And even after the movie ended, "perception of the real world was enhanced as well. A lamppost jumped out from the background, and the trees, cars and people looked somehow more vivid."

Did the 3-D movie cure his poor depth perception and make his eyes point in the same direction? Read the rest of the article to see what happens! Stereo Sue makes an appearance in the article too!

It was a very interesting article, that I was so excited to read! Has anyone else found any great articles, that you were excited to see that related to Vision Therapy? Pass it along!

Have a happy 4th of July!
