I have had a lot of vision problems with my PCS. In fact, I had a major relapse that was worse than the initial blow to the head, and the relapse was caused solely by computer work. After that, I developed problems with severe eyestrain, headaches caused by eyestrain, and severe photophobia.

These symptoms got worse for about 6 months and have been gradually improving now for about 6 months. I started vision therapy about a month and a half ago and so far it is helping to speed up my recovery--not only with the visual issues but with all of my symptoms.

I think that in my case, the vision problems have been exacerbating the rest of my symptoms by continually stressing out my brain and preventing it from healing properly.
