Prisms and Traumatic Brain Injury

Published on
March 1, 2022

What are prisms? 

Prisms are prescribed in the regular lenses. They are often used during treatment. The lenses are used to shift light in the eyes. As a result, it changes the perception of space for that individual. Prisms were commonly seen as a means of correcting an imbalance. Yoked prisms are often used in this particular case. The most common treatment for post-traumatic vision syndrome is using base-in prisms in small amounts. This can be in the order of about a quarter diopter to one or more diopters in its base-in.

How long does it take for symptoms to appear after a traumatic brain injury?

Symptoms often appear immediately, so neuro optometrists prefer to see patients in an inpatient setting so that they can address the problem promptly. It is not uncommon for optometrists to see this condition persist for years after an injury. Many eye doctors that specialize in working with brain injury patients see patients who were injured three or four years ago but continue to exhibit symptoms. Following their clinical examination, they discover that the post traumatic vision syndrome still exists. They demonstrate that to the patient. Several different lenses and prisms are used to demonstrate how changes can be made. They also collaborate with the other rehab professionals the patient is seeing. The symptoms of a brain injury never fully go away, so patients are usually grateful to find that there are things that still exist to help them.

Prism glasses: what are their benefits?

These benefits can be obtained by using prisms:

  • Alleviate double vision
  • Get rid of headaches
  • Reduce eye strain and fatigue
  • Relieve neck, shoulder, and back pain
  • To reduce stress
  • Enhance comfort
  • Stabilize near-task performance
  • Maximize efficiency

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.

  • 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.
