Dua’s layer

A new layer of the human cornea, called Dua’s layer, has been discovered by Harminder Dua, a researcher at the University of Nottingham in the UK. The new ‘layer’ is a 15-micron thick layer that sits at the back of the cornea, between the corneal stroma and Descemet’s membrane. Being incredibly tough, it plays a vital role in the structure of the tissue that controls the flow of fluid from the eye.
