There is a condition of the cornea, the part of the eye nearest and dearest to my heart, that has a peculiar and interesting name: crocodile shagreen.
Crocodile shagreen is an appearance of the cornea that we see when examining eyes under the microscope. It is not something that typically elicits a visit on the part of a patient, as it is usually asymptomatic. The pattern that we see when we examine the eye is said to closely resemble crocodile skin.
Given its asymptomatic and benign nature, I almost always omit mentioning it to patients, lest they think that they have small reptiles swimming around in their eyeballs.
