Blurred or double vision/
loss of vision
Facts
-
-
When looking for signs of a brain tumour, there are two main types of visual abnormality to be aware of: changes to vision such as blurred or double vision and abnormal eye movements.
-
Other visual symptoms that may be caused by a brain tumour include worsening in vision and eyesight – be particularly aware where these have occurred suddenly.
-
Double vision is where your eye doesn't work quite as it should and you see two images of a single object that you are looking at rather than one. With blurred vision, a single image will appear, but will be unclear.
Indications of sight problems include:
-
-
Difficulty seeing when the teacher displays information at the front of the room at school or college.

Reduced awareness of people or objects to the sides, above or below (indicating a loss of peripheral vision).
