New step in treating blind patients

In the "Sciene Translational Medicine" issue on February 8, US scientists published positive results in the study of using gene therapy to restore vision in congenital blind patients due to Genetic genetic errors.

In the first trial, gene therapy was tested with one eye for 12 patients and gave good results when placed in the other eye of 3 patients. This shows that this treatment is safe, effective and acceptable to the body.

Gene therapy is suitable for patients who are blind due to genetic genetic errors

At the second test, three patients from the first trial and six completely blind people agreed to try the therapy. After this test, the patients are better able to see in dim light and two more people can identify obstacles in low light conditions. No side effects have been reported in these patients.

Patients reported that after a period of treatment, they could walk when it was dark, go shopping and identify faces. Those are things they couldn't do before.

Treatment for patients with visual impairment by gene therapy is suitable for patients who are blind due to genetic genetic errors, diseases caused by light-receiving cells in damaged retina are called congenital blindness. The cause of the disease is the mistake of 13 key genes on the eye, losing the ability to see and abnormal movements of the eye in early childhood and often lead to complete blindness between the ages of 20 and 30 .

Gene therapy is one of the most attractive areas of biotechnology, promising the ability to prevent or reverse genetic diseases. However, this new field also sometimes fails due to the unpredictable or controllable reactions of the immune system. However, the researchers say this gene therapy has so far not caused side effects and positive treatment results have been maintained for many years.
