Scientists have discovered a previously unknown layer lurking in the human eye.
The newfound body part, dubbed Dua’s layer, is a skinny but tough structure measuring just 15 microns thick, where one micron is one-millionth of a meter and more than 25,000 microns equal an inch. It sits at the back of the cornea, the sensitive, transparent tissue at the very front of the human eye that helps to focus incoming light, researchers say.
The feature is named for its discoverer, Harminder Dua, a professor of ophthalmology and visual sciences at the University of Nottingham. Dua said in a statement that the finding will not only change what ophthalmologists know about human eye anatomy, but it will also make operations safer and simpler for patients with an injury in this layer.
