Do I have to see an M.D. to check my eyes for diabetic retinopathy?

Or can I just have my optometrist check them when I go for my glasses and contacts exam? I know I have diabetes and I know I should get my eyes checked once a year.

I bruise easily and was told it could be a sign of diabetes. I am only 27. Also what do doctors do to test for diabetes?
