NORA meeting topic: The Prism Experience
12:00pm - 1:00pm
Purpose of Meeting:
This workshop introduced a variety of prisms for club members to wear to gain an understanding of how their patients with TBIs may see the world. It also demonstrated some treatment and therapeutic strategies for these patients. Three stations were set up which were rotated every 15 minutes.
A brief introduction on how prisms work was presented by Jason. Jonathan proceeded to explain the set-up of the various stations for this exercise, and the meaning of how these tests not only demonstrate how some patients may visualize the world and interact with it, but how some of these techniques can be used therapeutically.
Station 1 had a line, and members would wear various yoked prism glasses to experience a spatial shift, and would attempt to walk straight down the line. Station 2 had timed eye trails and alphabet tracking page tests which members would attempt to resolve while looking through various prisms, which would induce spatial shift and/or diplopia. Members could also look through prisms with temporal field loss simulation via tape, and attempt to read. Station 3 had another line taped to the floor, and members would wear prisms in different directions to induce image shifts, and attempt to walk along the line. Prisms were worn and bean bags were thrown at a trampoline, and attempted to be caught by the thrower as it bounced back. This demonstrated difficulty in hand-eye coordination when one’s spatial world is shifted.

What our members thought about the meeting:
"The prisms exercise was really helpful, but very challenging. It was difficult having to experience the patient's vision firsthand. It actually made me feel sick after a while, and I can only imagine what life is like for a person who is living with this daily."
"I feel a lot more empathy for patients with strabismus or amblyopia now that I've experienced it myself. It's incredibly disorienting and without the adaptive ability of normal brain function, I would be a very withdrawn person."
"It was great to learn how prism is used to shift an individual's spatial orientation. And the concept of using prisms to help with visual training, ie in patients with TBI, stroke etc."
