Really? Anatomy seems to be an inherently boring subject that rarely becomes "unbelievably interesting" to anyone other than anatomists, surgeons (especially when in surgery), and the occasional determined patient trying to figure out what went wrong. Still, without at least a working knowledge of eyelid anatomy basics, you won't be able to fully benefit from later discussions in this course. Not that you have to memorize all the technical terms that follow. Just remember where you saw them and that you can always come back for a quick refresher.
Far from just "a piece of skin covering the eye," the eyelid is one of the most complex structures in the body. Composed of multiple main layers with intricate connections, it's a remarkable tiny organ assigned a protective function far more important than "looking good."
To understand why perfectly healthy eyelids on one person can sometimes appear so different from those on another healthy person, you first have to learn the basic anatomy of not only the eyelid itself but also of the structures located immediately above, below, and behind the eye.
Likewise, to understand why some of the "beauty" of a youthful eyelid tends to fade over time, you also need to learn about the changing anatomical relationships and interactions between the lid, orbital, and surrounding periorbital tissues.
If you find yourself intimidated or bored by what may sound like technical minutiae, do consider this. Not until you've mastered at least the essentials of eyelid anatomy and physiology will you be able to evaluate the soundness (or lack thereof) or safety (or lack thereof) of the many disparate cosmetic procedures that now purport to restore aging lids to their once former glory.
So here we go, first with what's on the surface and then deeper down . . .
Over two million people have learned from us.
Maybe you should, too.
