Glaucoma is a group of eye diseases causing optic nerve damage. The optic nerve carries images from the retina, which is the specialized light sensing tissue, to the brain so we can see. In glaucoma, eye pressure plays a role in damaging the delicate nerve fibers of the optic nerve. When a significant number of nerve fibers are damaged, blind spots develop in the field of vision. Once nerve damage and visual loss occur, it is permanent. Most people don’t notice these blind areas until much of the optic nerve damage has already occurred. If the entire nerve is destroyed, blindness results. Glaucoma is a leading cause of blindness in the world, especially in older people. Early detection and treatment by your ophthalmologist are the keys to preventing optic nerve damage and vision loss from glaucoma.- Kellogg Eye Center
London: Glaucoma, an eye disease that damages the optic nerve and can result in vision loss and blindness, can now be treated with a simple injection, eye surgeons have said.
In glaucoma, eye pressure plays a role in damaging the optic nerve.
A new technology developed by a US-based company relieves the pressure in the eye with a minimally invasive method, thus doing away with the need for scalpels and stitches, the experts noted.
It involves using a hypodermic needle to inject a tiny pliable drainage tube into the eye, allowing excess fluid to flow out, the Daily Mail reported.
The Xen Gel Stent developed by California-based AqueSys Inc is six mm long and about the width of a human hair. It is injected through a small self-sealing corneal incision using a simple, preloaded injector.
It was “quicker and safer” than current methods, Vik Sharma, a consultant eye surgeon at the Royal Free Hospital in London, was quoted as saying.
But the XEN Gel Stent is an investigational device, which means it has not been approved by the US Food and Drug Administration (FDA) yet.
