Retinal Detachment: Warning Signs and Repair: How It Works, Explained Simply

Video Transcript

A retinal detachment happens when the retina lifts away from the wall of the eye. It is an emergency, and it needs care right away. The retina is the thin light-sensing layer lining the back of the eye. It only works while it stays in contact with the wall beneath it. Most detachments begin with a small tear. The clear gel that fills the eye can pull on the retina and open a break in it. Fluid then passes through that break and collects underneath, peeling the retina away like wallpaper lifting off a wall. Warning signs include a sudden burst of new floaters, flashes of light, or a dark shadow or curtain moving across your vision. These symptoms are painless, which can make them easy to dismiss. Do not wait. Same-day care gives the best chance of saving vision. Treatment is surgical. A tear alone can sometimes be sealed with laser, while a detached retina may be repaired with a gas bubble, a band around the eye, or surgery inside the eye. Most detachments can be reattached. How much vision returns often depends on whether the center of the retina was involved, and on how quickly treatment happened. This video is for general education only. It is not medical advice. Ask your eye doctor what's right for you.
