It has traditionally been thought that cornea of human eye consists of 5 layers starting from the top to bottom namely, epithelium, Bowman's layer, stroma, Descemet's membrane and endothelium. But it's time for a rewrite now as scientists at the University of Nottingham have discovered a new layer in the cornea.
Named as the Dua's Layer after the academic Professor Harminder Dua who discovered it, this new layer is located at the back of the cornea between the corneal stroma and Descemet's membrane.
According to the researchers, the newly discovered Dua's Layer is incredibly tough and is strong enough to be able to withstand one and a half to two bars of pressure.
From a clinical perspective, understanding the properties and location of the new Dua's layer could help surgeons to dramatically improve outcomes for patients undergoing corneal grafts and transplants, say the researchers.
The study is published in the journal Ophthalmology.
