The Louisville Courier-Journal says that Rand Paul is only certified as an ophthalmologist by himself. Literally by himself. He is not certified by anything connected to the AMA but instead has his own group called the National Board of Ophthalmology. (To be clear, he dropped his AMA related certification and set up his own certifying group.) He set this group up because the AMA related one requires recertification every 10 years so doctors keep up with education. He is the owner and President of the group. It has a PO box. It has no known standards for certification.
To be fair, he doesn't need certification to practice in Kentucky but I'm thrown for a loop by the dishonesty inherent in setting up your own "Board" to certify yourself because it is clearly being done to give the impression to the public that he's certified. That's really lying.
As a final note, there are 7 others certified by Rand Paul's "Board," but they are all also certified by the regular Board. Makes me wonder if he paid them to join or somehow offered them something so his Board looks less phony than it otherwise is.
