An injury in the eye is often a minor one, but it can be serious if it is treated incorrectly.
In a new study, a team of researchers in the US has found that removing a bone in the upper eyelid can correct the problem in just 30 days.
The team has also found that they can correct a large number of cosmetic surgery-related injuries and conditions, including keratoconus, rosacea and keratoplasty.
The research was published in the journal Plastic Surgery.
The study was led by Dr Rajeev Bhasin of the University of California, San Francisco, and his team, which included researchers from the Mayo Clinic, University of Illinois, Ohio State University, Harvard University and Boston University.
They said they had identified a “totally novel” pathway that is activated when the collagen in the eyelid is ruptured, releasing the collagen and its proteases from within.
They found that the collagen is able to enter the eyelids via a type of “pore” that was previously unknown.
In addition, they found that when they injected the collagen into the eye of a monkey that had been treated with a collagen transplant, they could fix a large percentage of the damage to the cornea and cornea tear without any further treatment.
Dr Bhas in the study said the collagen that was injected was not injected directly into the corneal tear, but into a tiny portion of the tear.
“If you inject collagen into a large tear, you inject a large amount of collagen, and if you inject the collagen there, you can actually create an inflammatory process in the tear, which causes it to grow, so that it grows back faster,” he said.
“This new mechanism has been described in the literature for over a decade, but no one knew where it was, and we thought, why not use it?”
Dr Bisin said the researchers were interested in understanding how this process works.
“We were trying to figure out what happens in the body when collagen is injected into the tear,” he explained.
“So, what happens is we inject a lot of collagen into an area of the eye that is normally damaged.
And then the corona, which is the outer layer of the retina, becomes damaged and it starts to swell, which results in the tears growing, which creates inflammation in the coronal space, which also causes inflammation of the surrounding tissue.”
Dr Biasin said one of the reasons for their work was to see if it was possible to treat keratitis using a new protein-based treatment.
“There are a number of proteins in collagen that are actually active in keratosis pilaris, and the protein in the collagen can stimulate these proteins in the surrounding cornea,” he told ABC News.
“It has been known for a long time that you can activate a protein that you call the p-protein, and when you activate this protein, the coracoid is stimulated, and that’s what we found that activated the p protein in our animals.”
“And then, once activated, the p proteins are able to be released into the surrounding eye.
So, we were hoping that, once the coricoid was activated, we would be able to stimulate this protein in a similar way.”
Dr Gabor Krens, who studies cornea repair at Boston University, said that while the protein injection was not a new idea, this was the first time that the team had used it in a human model.
“They were looking at a human cornea, and it’s been known since the 1990s that the coroplast is a very strong protein, so this protein was a natural candidate to use in that case,” Dr Krenst said.
Dr Krensh added that although it was very early days for the research, the results could have important implications for future surgeries.
“The cornea is the largest part of the coracles, and there are also other tissues that are injured in the face, so it’s going to be important to see whether this is able, and how it is able or not, to restore the corium,” he added.
