You would have thought they’d know all the bits & pieces by now, but it looks like buffy’s going to need a refresher:

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.

I can’t find the reference. PubMed just defaults to ‘dual layer’ on a search….

From the non science press stuff, I reckon there will be some debate about this…..a collagen layer in the stroma? The stroma is collagen. Must mean an even more organized section than the rest of it. The fibres have to be very structurally arranged for the cornea to be clear anyway.

Here’s the Wiki entry on Dua’s layer, but it’s one of those with an exclamation mark at the top:

I didn’t have much time to look before. I was looking for a paper in a peer reviewed journal. I’ll go to your link now and see if it leads anywhere.

Read an article this arvo by my sister’s immunologist (I think when he was a jnr doktar) about preservation of vision (6/18) in an eye with confirmed gas gangrene – they said it was the first case of useful vision preservation. I think from the 70s.

>gas gangrene

Sounds nasty.

Yep. He lost the other eye completely.

Just did a Google image search – one glimpse was enough (too much, actually)

Found it, but only by going to “Ophthalmology” journal website. You can read the abstract, but you have to buy the paper:

And I once checked the eyes of a person with a gangrenous foot (diabetic)….gag,gag,gag. Don’t know how I didn’t vomit. The smell is horrible.

Yes, yes it is. But sacral ulcers are worse.
