Anatomy of the Eye Video


length: 25 minutes

This second video is chock-full of high-yield anatomy facts. The eye is a complex structure with layers, lens, muscles, receptors, that is surrounded by many bones. I keep things simple in this video, and correlate directly with the anatomy chapter from the book. I’ve also scanned in an entire head CT to help you correlate the cartoons with real clinical imaging. Here are screen-captures from this video:

Screen Captures from this Video:

video-orbicularis.jpg
The orbicularis closes the eye, while the levator raises the lids. Each has their own innervation (cranial nerves 7 and 3)

video-limbus.jpg
The external eye is covered by the thin conjunctival tissue, which inserts at the limbus of the eye.

video-ctorbitalmuscles.jpg
The nasolacrimal duct drains tears from the eye surface into the nose – explaining why your nose runs when you cry. You can see this duct on CT.

video-punctum.jpg
The punctum is small and located on the medial lid, near the nose. We can put plugs in the punctum to help with dry eye.

video-lashpunctum.jpg
This patient has an eyelash that’s stuck in the punctum.

video-eyeglobe.jpg
The cornea and sclera are continuous with each other … however, the cornea is clear because it is relatively dehydrated.

video-cornealayers.jpg
The cornea has five layers – the endothelial layer acts as a pump to keep the cornea dehydrated.

video-anteriorchamber1.jpg
The ciliary body sits behind the iris and tethers the lens in place by a 360 degree network of zonular fibers.

video-maturecataract.jpg
The lens has the configuration of a peanut M&M with an outer capsule, middle cortex, and central nucleus. In this advanced cataract, the cortex has liquefied into a milky consistency, and the central brown nucleus has sunk to the bottom.

video-eyemuscles.jpg
Eye movement is controlled by rectus and oblique muscles that tether the eye and connect at the orbital apex.

video-orbitalbones.jpg
The orbital walls are formed by seven separate bones. They aren’t that difficult to learn when you review them one-by-one.

video-ctorbit.jpg
You can see the orbital bones and the extraocular muscles on CT – a coronal view like this one works best.

I would like to partner with you.
I am planning to establish an Online University for the poor communities of Madagascar. One of the subject I want to offer (not for making profit) is Ophthalmology.

Could you let me know how can it be possible?

Excellent video;
Thanks a lot.

Great!



Comment by philantoo — February 24, 2011



The cornea is not dehydrated relative to the sclera. It is actually the other way around, due to the cornea having ~4 times the number of glycosaminoglycans as the sclera. The hydration provides the proper spacing between collagen bundles to cause destructive interference, reducing scatter.

Great work thank you alot for the great efforts:)

I am a teacher of young children who are blind and low vision. I have been using your videos to upskill my colleagues on the anatomy and physiology of the eye so they can better understand the children’s eye conditions. Your style is clear and concise and that makes it accessible to everyone. Thanks and please do more! A series on common eye conditions would be very helpful!
