I Spy With My ENORMOUS Eye!
The doctors take a close-up look at how the eye works, and Dr Chris finds out what body fat does by looking at some of his own under a microscope. Meanwhile, over in accident and emergency, one patient has a mystery rash and another has a bad infection under her fingernail.
