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).

This 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 don't normally need to stay in hospital overnight.

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

  • your vision may be blurry
  • your eye may be sore and red – take paracetamol if you need to
  • you may need to take time off work
  • you may not be able to drive
  • you may need to avoid flying (if you have had a bubble of gas put into your eye)

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

Important

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:

  • are short-sighted
  • have had an eye operation (such as cataract surgery)
  • have had an eye injury
  • have a family history of retinal detachment

Important

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