What Are Retinal Tears and Detachments?

The retina is the inside lining of the eye. It turns light into nerve signals. These signals are then sent to the brain where they become the images you see. The retina may be torn or detached due to aging, an eye injury, or other problems. Tears and detachments are painless. But they often cause troubling or serious vision changes. If you have symptoms of a tear or detachment, contact your eye care provider right away. If you can't reach your eye care provider, go to the emergency room. Retinal detachment is a medical emergency.
