Abnormal eye movements

Abnormal eye movements


  • When looking for signs of a brain tumour, there are two main types of visual abnormality to be aware of: abnormal eye movements, and changes to vision, such as blurred or double vision.
  • Abnormal appearance or movements of the eye are important symptoms to look out for – for example a new squint (eyes looking in different directions), one eye is bulging, wobbly, quivering or flicking eyes.

Other visual symptoms that may be caused by a brain tumour include blurred or double vision, and a worsening in vision and eyesight – be particularly aware where these have occurred suddenly.

If you're a teenager and you're concerned about your symptoms, it's best to get them checked out by your GP or book an eye check at a local optician. Further information about eye problems and eye health can be found at NHS Choices.

If you're a parent or carer of a teenager and you're concerned about their symptoms, explain that you think they should go to the GP or a local optician and offer to make them an appointment. Bear in mind that, depending on their age and circumstances, they may choose to go on their own, although many appreciate having a parent or carer with them whatever their age.
