What is the name of the skin fold of the upper eyelid?

Reno, neither did I but really, I should have known, because every physical feature has a proper name. It's logical that anatomically, everything has a descriptive term.. A medical book can't really refer to an obscure part of the body as a thingamagig or a whatsitsname, I guess!

I find geological physiology fascinating. Real examples of evolution.

The native Bushman of Southern Africa also have an epicanthic fold in their eyelids.

Laudy Miss Claudy, so true because my family originates from west africa and i have that epicanthic fold as well..

medically most prominent in trisomy 21 which was once referred to as mongolism or mongoloid features

Laudy Miss Claudy, They mention the Khoisan.

I've been wanting to see a doctor because it looks like fat on my eyelids

Epic-an-thic. Trump.

I wish they'd leave ones folds out of it.
