SIGNS TO WATCH FOR

RETINAL detachment can happen at any age, but people who are short-sighted are more at risk, possibly because their retinas are more fragile.

Another risk factor is having had cataract surgery.

The NHS advises seeing an optician urgently, going to A&E or calling 111 if you have:

DOTS or lines ( floaters) suddenly appearing in your vision or these suddenly increase in number.

FLASHES of light in your vision.

A DARK shadow or ‘curtain’ moving across your vision.
