Detached retina (retinal detachment)

A detached retina is when the thin layer at the back of your eye (retina) becomes loose. It needs to be treated quickly to stop it permanently affecting your sight.

Check if you have a detached retina

Symptoms of a detached retina include:

Urgent advice: Get help from NHS 111 if:

  • floaters (dots and lines) suddenly appear in your vision or suddenly increase in number
  • you get flashes of light in your vision
  • you have a dark "curtain" or shadow moving across your vision
  • your vision gets suddenly blurred

You can call 111 or get help from 111 online.

Treatment for a detached retina

You'll be referred to hospital for surgery if tests show your retina may be detached or has started to come away (retinal tear).

Surgery will usually stop your vision getting worse.

What happens during surgery for a detached retina or tear

Surgery to re-attach the retina or fix a retinal tear may involve:

  • removing and replacing the jelly inside your eye (vitrectomy)
  • attaching a small band around your eye to push the wall of your eye and retina closer together (scleral buckling)
  • injecting a bubble of gas into your eye to push the retina against the back of your eye (pneumatic retinopexy)
  • sealing the tear in your retina with laser or freezing treatment (cryotherapy)

It's usually done with local anaesthetic, so you're awake but your eye is numbed.

You do not normally need to stay in hospital overnight.

You may be asked to lie or sit in a particular position for up to 7 days after the surgery. This is so that your retina is in the correct position to help it heal.

Recovering from a detached retina

Recovery time after surgery for a detached retina varies. But as a general guide, for 2 to 6 weeks after surgery:

Most people are eventually able to return to all their normal activities.


Call the hospital or go to A&E if the pain, redness or blurriness gets worse after surgery. You may need further treatment.

Causes of a detached retina

A detached retina is usually caused by changes to the jelly inside your eye, which can happen as you get older. This is called posterior vitreous detachment (PVD).

It's not clear exactly why PVD can lead to retinal detachment in some people and there's nothing you can do to prevent it. But it's more likely to happen if you:

Important: If your symptoms come back

You can get a detached retina more than once. Get medical help as soon as possible if the symptoms come back.
