A new way to treat macular degeneration of the retina
Many older people suffer from macular degeneration of the retina. The disease, which, according to scientists, can be cured by transplantation of retinal cells. While this project is under active development, but scientists hope within 5 years to apply this technology to treat people.
As you know, macular degeneration and the retina age-related disease, 25% of people over 60 suffer from it. 14 million Europeans completely lost vision due to this disease. The cause of this disease is damage to the epithelial cells of the retina (the layer of cells located under the retina) responsible for the processing of external light rays. Experts distinguish two main types of macular degeneration – dry degeneration occurs in 90% of cases, and the wet form in 10%. Unfortunately, I have to admit, effective methods developed to treat wet degeneration, but the dry form of this disease is still incurable.
A group of scientists from the University of Sheffield (UK) were created artificially by the epithelial cells of the retina, taking previously a colony of stem cells from a human embryo. The main sources of human stem cells are organs and cells of embryos. The researchers hope during a 45-minute operation to implant an artificial cell in a patient’s eye. Was already conducted preliminary experiments on mice, using this technology all the “participants” renewed vision. The only thing that bothers scientists is the possible complications after surgery.
