What Are The Common Retinal Diseases?

Any disorder that affects the retina or the light-sensitive structure that sits in the back of the eye is considered a retinal disease. The retina contains cells that trigger impulses that travel through the optic nerve to the brain. The cells in the retina contain rods and cones that help organize the visual information before transmission. When the impulses reach the brain, a visual image is produced. The most common symptom of a retinal disease is vision abnormalities. These abnormalities include general vision loss, floating specks or cobwebs, peripheral or side vision defects, and blurred or distorted vision.
