Retinal disease is a broad term used to describe any condition that affects the retina, the light-sensitive tissue at the back of the eye. Retinal diseases can cause vision loss and blindness, and can be caused by a variety of factors, including genetics, aging, trauma, infection, and inflammation. Common retinal diseases include age-related macular degeneration, diabetic retinopathy, retinal detachment, and retinitis pigmentosa. Treatment for retinal diseases varies depending on the type and severity of the condition.
