The newest addition to human anatomy is just 15 microns thick, but its discovery will make eye surgery safer and simpler. Harminder Dua, a professor at the University of Nottingham, recently found a new layer in the human cornea, and he's calling it (can you guess?) Dua's layer.
Dua's layer sits at the back of the cornea, which previously had only five known layers. Dua and his colleagues discovered the new body part by injecting air into the corneas of eyes that had been donated for research and using an electron microscope to scan each separated layer.
The researchers now believe that a tear in Dua's layer is the cause of corneal hydrops, a disorder that leads to fluid buildup in the cornea. According to Dua, knowledge of the new layer could dramatically improve outcomes for patients undergoing corneal grafts and transplants.
"This is a major discovery that will mean that ophthalmology textbooks will literally need to be re-written," Dua says. "From a clinical perspective, there are many diseases that affect the back of the cornea which clinicians across the world are already beginning to relate to the presence, absence or tear in this layer."
The study appears in the journal Ophthalmology.

Yea for medical science in helping all of us continuous sight!
This discovery will ensure that people will still be able to read popular science. Unless you guys have a braille version I don't know about.
I think its great that this new human body part was discovered without any experimenting on animals and with a donated eye..
Margo54 how can new human body parts be discovered experimenting on animals?
How many things are still waiting to be discovered because nobody bothered to look close enough, or question their teachers?
Accepting anything without question makes you a fool.
How many other body parts are named after people? I'm not a body part expert, but it seems like there can't be many, if any. I'm hoping this gets a logical name rather than a conceited name.
i have been in the field of corneal refractive surgery for last 27 years and I congratulate Mr Dua for his work.
Corneal biomechanics are poorly understood and we should be able to measure the proportion of various tissues in Cornea which are responsible for the rigidity of the cornea - a very vital issue according to me for the underlying biomechanics.
A small dehiscence in the weaker portion in the layers of cornea leads to ectetic condition very much similar to hernea formation in the other part of the body
I have been experimenting but I am very much impressed with your work
God bless you
