eye problem after concussion

I had a concussion 6 weeks ago that has resulted in my left eye seeing dimmer than my right. this was the case when it first happened. it had become better after a fews days, but the past week or so it has gotten worse.... I went to an optimologist to have it checked out yesterday. no problems with pupils.. he did several tests including one where u look into a box and click button when you see light...... no problems at all.... everything seems normal... except vision in left eye is darker/dimmer causing overall vision to appear blury/unfocused....do you know what could be wrong?

I strongly recommend you see an ophthalmologist right away since something abnormal seems to be going on and I am concerned.  Other testing including an OCT of the retina may help to show the problem if there is one.  Sometimes seeing the specialist can either help find the problem or help put your mind at ease by letting you know that everying is actually OK but you need to make the appointment to see a board-certified ophthalmologist as soon as possible.
