Retinal detachment is an eye problem that happens when your retina (a light-sensitive layer of tissue in the back of your eye) is pulled away from its normal position at the back of your eye. There are many causes of retinal detachment, but the most common causes are aging or an eye injury. Since retinal detachment is often caused by aging, there’s often no way to prevent it. But you can lower your risk of retinal detachment from an eye injury by wearing safety goggles or other protective eye gear when doing risky activities, like playing sports.If you experience any symptoms of retinal detachment, go to your eye doctor or the emergency room right away. Early treatment can help prevent permanent vision loss. It’s also important to get comprehensive dilated eye exams regularly. A dilated eye exam can help your eye doctor find a small retinal tear or detachment early, before it starts to affect your vision.
