Harminder Dua an Indian doctor from Britain has found a new layer in the human eye behind cornea which would play a vital role in curing blindness caused due to glaucoma. Glaucoma is one of the greatest causes of blindness, caused by the drainage of fluid in the eye. He found that this layer is 15 microns in thickness and is marvelously rigid. This layer may affect the flow of liquid in the eye upto a great extend.
In earlier studies cornea was suppose to have 5 layers - Corneal Epithelium, Bowman layer, Corneal Stroma, Descemet membrane and Corneal Endothelium.
The new layer is named Dua's layer which is located between the 2 layers of the cornea, corneal stroma and descemet membrane.
Dua said "This discovery we will claim to write ophthalmology textbooks again. Many diseases affect the back of cornea and studies are already started to relate majority of them with this layer."
The layer will add up to sieve like mashwork called Trabecular mashwork(TM). TM is a band of tissue made up of bone marrow between trabecular cells and endothelial cells which extends all over the circular channel in the eye. These beams of bone marrows form the mashwork. TM manages the flow of liquid in the eye, defect in which causes high pressure in the eye.
Further study on this layer will surely bring a vast change in theories of the cornea and cure of blindness.
