Can Brain Tumors Affect Your Vision?
Yes, they can. Although eye problems typically stem from conditions unrelated to brain tumors—such as astigmatism, cataracts, detached retina and age-related degeneration—they can sometimes be caused by tumors within the brain. Brain tumors can lead to vision problems such as:
- Blurred vision
- Double vision
- Abnormal eye movements
- Sensitivity to light
- Loss of vision
How do brain tumors cause eye problems?
Vision problems can develop when a tumor places pressure on a certain area of the brain. The occipital lobe, for instance, is responsible for processing everything that a person sees, so a tumor in that region of the brain could cause a variety of sight issues. Or, a tumor affecting the brain stem could result in double vision. Eye problems can also occur when a brain tumor exerts pressure on the optic nerve or when pressure within the skull causes the back of the eye (optic disc) to swell (a condition known as “papilledema”). Finally, brain tumors that invade or push on any of the neural connections between the eyes and the occipital lobe can cause loss of parts of the visual field (blind spots).
