New Human Body Part Discovered
Time to rewrite the textbooks!
Kind of an unusual thing happened in the field of anatomy. Researchers found a previously unknown human body part. It’s inside the eyeball, and it’s very small. At 15 μm (microns) thick, the newly discovered layer of material is so small that even calling it a new body part feels inappropriate. That’s what it is, though. A new body part.
Named for Harminder Dua, the ophthalmology professor who made the discovery, the Dua’s layer is one of six known layers of the cornea. (The cornea is the transparent lens in the front of the eyeball that focuses light going in towards the retina.) Now that we know about this additional layer, researchers say that doctors will be better able to diagnose and treat certain conditions, especially injuries to the cornea. The discovery will also make corneal transplants easier. Said Dua, humbly, “This is a major discovery that will mean that ophthalmology textbooks will literally need to be re-written.”
