Changes to vision could be blurred or double vision and changes to eyesight.
A common visual abnormality is a squint. This where the eyes look in different directions. It is very rare for a squint to be caused by a brain tumour. If you notice that your child has a squint, this should be checked out by an eye specialist.
Babies and young children may show some changes in their behaviour which alert you to a problem with their vision.
This could include a reduced ability to focus on people or toys in front of them or struggling to follow moving objects with their eyes.
They may appear clumsy, stumbling and bumping into things.
