Prisms and Traumatic Brain Injury

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.
