After a traumatic brain injury, some patients experience something known as Post Trauma Vision Syndrome. This is a very serious condition that can have a dramatic impact on a person's ability to read. Naturally, this can also then limit the person's options for work, travel, recreation and much more.
The issue is that the brain stops looking at letters in the proper way; instead of recognizing how they work together to form words, the person sees only the individuals letters, all on their own. This makes it incredibly hard to organize them into words, so the person can no longer read easily or, in some cases, at all. He or she may still recognize the letters themselves and be able to differentiate between them and even name them, but the person can't put them together correctly.
This issue can be altered over time, and some subjects who get proper treatment have shown improvement. However, every case is different, and there is no guarantee that reading ability will ever change or be fully restored to what it was before the injury.
The treatment includes both bi-nasal occlusion and the use of prisms.
In some patients, the problem is a bit different; it all depends on the case and how the brain was injured. These patients will sometimes still be able to read, but it's very easy for them to get confused and lose their place. They may read half of the page and then suddenly not know where they are, or they could read the same information repeatedly.
