For the blind people, the thought of a treatment to restore sight may seem like an impossible dream, but it may eventually become a reality after a blind person's eyesight was restored by scientist last year. The treatment works by replacing those cells in the eye that are known as retinal cells damaged or worn out by diseases like macular degeneration. Macular degeneration is a common concern especially for the elderly, as it can lead to colossal vision loss in one or both eyes. This is the most common disease that leads to blindness in the elderly or those who lose sight due to diabetes. It wreaks havoc on the central vision of a person. Stem cell therapy can treat this.
People who suffer from macular degeneration are the ones who could benefit most from this stem cell treatment. But researchers also think it might work for other types of loss of vision. Doctors took the world's first step by conducting a clinical trial using donor stem cells to create tissue that has been transplanted into patients with a blinding condition. Researchers say the trial provides clues on how to repair the loss of eye tissue using organ donor stem cells. The study focused on limbal stem cell deficiency (LSCD), which can be caused by chemicals or heat damage to the eye or caused by a disease called aniridia. This leads to severe vision loss as well as chronic pain and redness in the eyes. In this condition, cornea becomes scarred and opaque where the normal and healthy cornea is transparent. These samples of the cornea are taken from people after death who has donated their eyes. Then stem cells are grown that have the unique ability to transform into other types of cells–into tissue that is ready for transplantation.
Age-related macular degeneration (AMD) and other more severe eye conditions require sustainable treatments, preventing a steady decline in one's quality of life. There are limited treatment options for visual impairments affecting the quality of life, but Stem Cell treatments, an often overlooked method of therapy, have shown time and time again through various studies and successful treatment outcomes that there are significant advantages in using Stem Cells for visual impairment.
