Do perfectionism & OCD link?

I'm a massive perfectionist. Everything has to be done to the best standard, and even when it is, I'll still pick faults & never am satasifed. If I get distinctions in my exams, I'm never happy, always thinking I could do better. It causes me a lot of anxiety, but in response to anxiety I work even harder. I was just wondering if it could be linked to OCD in some way?
