Age Loss of Vision - Prettycommon phenomenon among all segments of the population. Scientists hope that with time this process can be stopped, and have already made a huge step towards achieving this goal. British ophthalmologists announced that they were able to successfully perform an operation to stop the development of the most common cause of vision loss among the elderly. They used a rather unusual approach, which involves the delivery of a special gene to a specific group of cells using a safe virus.
The most common cause of vision loss isPeople older than 50 are considered age-related macular degeneration (WDD). It affects millions of people around the world, impeding reading and even facial recognition. This is subsequently destroyed by retinal cells due to an aggressive reaction of the immune system caused by the activity of proteins.
Experimental therapy isdelivery to the cells of the retina of a particular gene that blocks the immune response. For the gene to be delivered correctly, the researchers use a safe virus that is placed in the back of the eye during surgery. According to the ophthalmologist Robert McLaren, this operation helps to effectively reduce inflammation and stop the degenerative process.
The first operation was performed by an 80-year-old resident.Oxford named Janet Osborne. According to her, she agreed to a pilot operation in the hope that it would help prove its effectiveness in preserving the vision of millions of other people.
First of all, I was thinking not about myself, but about otherspeople As for me, I only hope that my vision will not get worse. That would be fantastic, and would mean that I would not inconvenience my family.

To make gene therapy an official methodtreatment, the researchers will conduct other experiments. They need to prove the safety of the operation and its effectiveness. At all this, researchers can take at least two years.
Recall that the new method of restoring vision inIn 2018, Russian researchers also proposed. Their idea also consisted in the delivery of special proteins using a safe virus - the only difference was that ultimately this protein could produce light-sensitive cells needed for vision.
