Retinal degeneration is a term used to describe a group of diseases that affect the retina, the light-sensitive tissue at the back of the eye. These diseases can lead to progressive loss of vision and, in some cases, blindness. Retinal degeneration can be caused by a variety of factors, including genetic mutations, age-related changes, and other underlying health conditions. Research in this area focuses on understanding the causes of retinal degeneration, developing treatments to slow or halt the progression of the disease, and ultimately finding a cure. This research often involves the use of animal models, stem cell therapy, gene therapy, and other cutting-edge techniques to study and treat retinal degeneration.
