Retina
What is a retinal tear and how is it treated?
A retinal tear is a break in the retina, usually caused by the jelly inside the eye pulling on it. It often causes new flashes and floaters. A tear matters because fluid can pass through it and lift the retina off, causing a detachment. Many tears can be sealed in clinic with laser, which greatly reduces that risk.
Who is more at risk
- People who are significantly short sighted
- Anyone who has had a retinal tear or detachment in either eye
- A family history of retinal detachment
- Previous eye surgery or a significant eye injury
How a tear is found
Tears usually sit at the outer edge of the retina, where they cannot be seen without dilating the pupil and using a lens to examine right up to the periphery. This is why anyone with new flashes or floaters is examined with dilation rather than reassured over the phone.
Laser treatment
Retinal laser creates a ring of small scars around the tear that stick the retina to the wall behind it, so fluid cannot spread underneath. It is done in clinic with anaesthetic drops, takes a few minutes and feels like brief pinpricks or flashes of bright light.
Laser does not remove the floaters and does not restore any vision already lost. Its purpose is to prevent a detachment. You will be reviewed afterwards, and told which symptoms mean you should return immediately.
When to seek urgent assessment
- A shadow or curtain spreading across your vision, suggesting the retina is detaching
- A sudden increase in floaters or flashes after laser treatment
Frequently asked questions
- Is laser treatment painful?
- Most people describe brief pricking sensations and dazzling light rather than pain. Anaesthetic drops are used and no needle is needed in most cases.
- Can I fly or exercise afterwards?
- Advice depends on the tear and the treatment, so follow the instructions given to you at your visit rather than general guidance.
