Right side smaller than left side. Face is uneven including eyes. Don't know why. What can be the reason?

Just starting to be noticeable. Four years ago I realized my eyes were on even right being smaller than the left. Told my family doctor. She didn't do anything about it because she didnt see it. Different doctor same problem. I suggested that it might be graves disease but lab results are normal. She referred me to an ophthalmologist which I will be seeing at the end of this month. Now I feel it has to do with a neurological problem. It is very noticeable now.
