According to a report by the "China Times Times," Taiwan reported on May 16, with the advancement of biomedical technology, researchers have developed a retinal patch that is cultured with stem cells and can be used to treat sudden and severe drops in vision. Of the crowd, and got results in the trial operation. According to reports, macular degeneration of the retina is a common aging-type visual deterioration, and the proportion of the population that causes vision loss is as high as 50%, and the vast majority occur in developed countries because the per capita life expectancy is high, so the problem is particularly acute. The decline of cells in the macula is a huge flaw in the evolution of mammals. The blood vessels at the bottom of the human eye are not behind the eyes but at the bottom of the eye, and photoreceptor cells in the fundus are in the grab position. If there are abnormal blood vessels in the fundus, the blood vessels may infiltrate the liquid in the eye (the aqueous humor) into the macular area in the center of the retina, which in turn causes the macular cells to flake off. The 86-year-old Douglas Waters discovered that his eyesight had deteriorated rapidly three years ago. After being examined by the hospital, he was diagnosed with macular degeneration caused by aging. He was also told that there was no effective method of improvement. But the hospital asked if he would be willing to become a volunteer for stem cell therapy. Watt agreed. A few months later, doctors surgically implanted a patch of stem cells at Watts' fundus. It is hoped that these stem cells will spontaneously differentiate into photoreceptor cells and become new and effective retinas. The results were quite effective. Before the operation, Watt’s right eye could hardly see anything, but after a few months of recovery, his vision was greatly improved. The daily actions were no problem and he could even read the newspaper. Can also arrange gardens with his wife. In addition to Watt, another 60-year-old female patient also received this treatment. Within one year after the operation, her vision improved significantly. She could not read the environment and she could read the book with her reading glasses. Reported, and read 60 to 80 words per minute. Dr. Peter Coffey of the Institute of Neuroscience at the University of California, Santa Barbara, published the results of a clinical trial in the journal Nature Biology. He said: "This is a real progress in the field of regenerative medicine and has been successful for the ages. Patients with macular degeneration provide effective treatments." Stem cells are the prototype of all cells because they are the areas where biotechnology medicine is most important. After years of research, the scientists discovered that stem cells are quite clever and they spontaneously become functions of nearby cells when they are in different environments. Therefore, when stem cells are implanted in the retina of the fundus, they will differentiate into photoreceptor cells of the retina. Can become macular cells. Dr. Kofrey said: "We hope that within the next five years, the operation can become universal and cheap, and it will become an affordable, ready-to-use therapy for patients with macular degeneration."
