Retinal regeneration

Retinas are like the cameras in our eyes. They help us see different colors, shapes and sizes of things around us. Sometimes, due to injury or diseases like diabetic retinopathy or macular degeneration, the retina gets damaged and we may lose our vision.

Retinal regeneration means repairing or replacing the damaged or lost cells in the retina so that we can see better. This can happen in a few different ways.

One way is through stem cell therapy. Stem cells are like magic cells in our body that can turn into any other kind of cell. So, scientists take stem cells and turn them into the specific kinds of cells that make up the retina. Then, they put these cells back into the patient's eye to replace the damaged ones.

Another way is through gene therapy. This involves delivering healthy genes to the damaged cells in the retina. These genes help the cells function better and in some cases, regenerate.

There is also research happening on other methods of regenerating the retina, such as using artificial retinas or electrical impulses to stimulate the remaining cells.

Overall, the goal of retinal regeneration is to restore or improve a person's vision by repairing or replacing the damaged cells in their retina.
