New eye layer has possible link to glaucoma
By examining human donor eyes using electron microscopy, the researchers were able to look at Dua's Layer beyond the central part of the cornea to shed more light on its features at the extreme periphery of the cornea. They discovered that the collagen fibres of Dua's Layer also branch out to form a meshwork and that the core of TM is in fact an extension of Dua's Layer.
