William E. Flanary is an American comedian, podcaster and ophthalmologist who performs under the stage name Dr. Glaucomflecken.

He was educated at Texas Tech University,[5] where he graduated Phi Beta Kappa and summa cum laude with a bachelor's degree in cell and molecular biology.

It was also while he was a medical student at Dartmouth that he was first diagnosed with testicular cancer (specifically, a highly curable stage 1a seminoma) at the age of 25.

This time the diagnosis was a stage 1b seminoma, and he had surgery to remove his remaining testicle, followed by androgen replacement therapy consisting of a weekly self-administered injection of testosterone.
