When do adjective clauses require a comma to introduce them?

Sometimes I see sentences in which a comma precedes the adjective clause, as in: The doctor, who treated my illness, has retired. Other times, I see it with no comma, as in: The doctor who treated my illness has retired.

Is there an easy rule to help me remember when to use a comma?
