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.
