Yes, eye doctors (optometrists/ophthalmologists) can often spot signs of a brain tumor during a routine eye exam by checking for optic nerve swelling (papilledema), pressure on the nerve, unusual pupil responses, or vision changes, as increased pressure from a tumor affects the optic nerve, leading to referral for brain scans (like MRI) for definitive diagnosis.
Some brain tumours can be detected through an eye test. But, it depends on the type of tumour and where it is. It's also good to remember that brain tumours are relatively rare and vision problems can be caused by a lot of different factors.
You usually see a doctor who specialises in diagnosing and treating problems of the brain and spinal cord. This might be a neurologist or a neurosurgeon.
Pressure on the occipital lobe: The occipital lobe is the area of the brain responsible for processing what you see. A tumor here can cause various sight issues, including blurred vision, sensitivity to light, or blind spots in your visual field.
A visual field test can detect vision loss caused by a possible brain tumour, stroke or eye diseases such as glaucoma or diabetic retinopathy.
Early warning signs of a brain tumor often involve headaches (especially morning headaches), seizures, persistent nausea/vomiting, vision changes, and unexplained weakness or balance issues, alongside potential changes in personality, memory, or difficulty with speech, though symptoms vary greatly by tumor location and size, so any new, concerning neurological changes warrant a doctor's visit.
During a comprehensive eye exam, an eye care provider can detect increased pressure in the brain, including swelling of the optic nerve or bleeding into the retina of the eye, which may indicate an aneurysm is present.
What is pseudotumor cerebri? Pseudotumor cerebri literally means "false brain tumor." It is likely due to high pressure within the skull caused by the buildup or poor absorption of cerebrospinal fluid (CSF). The disorder is most common in females between the ages of 20 and 50.
Facial Numbness, Tingling, and Sensory Changes
Many people with brain tumors feel numbness or tingling on their face. This happens when the tumor presses on or grows into the nerves. Symptoms can range from a little numbness to no feeling at all in some face areas.
A brain tumour can cause headaches, but it is unusual for this to be the only symptom. Headaches are usually dull and constant, and sometimes throbbing.
Symptoms of a brain tumour
seizures (fits) persistently feeling sick (nausea), being sick (vomiting) and drowsiness. mental or behavioural changes, such as memory problems or changes in personality. progressive weakness or paralysis on one side of the body.
Brain tumor red flags include persistent, worsening headaches (especially in the morning/night), new-onset seizures, unexplained nausea/vomiting, vision changes (blurred, double), balance/coordination issues (clumsiness, trouble walking), significant personality or behavioral shifts, weakness/numbness on one side, and speech difficulties (slurring, trouble finding words). These symptoms often stem from increased pressure or direct interference with brain functions, and their gradual or sudden appearance warrants medical attention.

Those diseases include age-related macular degeneration, cataract, diabetic retinopathy, and glaucoma. Other common eye disorders include amblyopia and strabismus.
If your healthcare professional thinks your CT scan shows a brain tumor, you might need a brain MRI. Brain MRI. MRI, uses strong magnets to create pictures of the inside of the body. MRI is often used to detect brain tumors because it shows the brain more clearly than other imaging tests.
A visual evoked potential (VEP) test is a noninvasive test that helps healthcare providers diagnose certain conditions that affect how your eyes and brain work together to interpret what you see. Some examples of these conditions include multiple sclerosis, head or brain trauma and a glioma on your optic nerve.
It often affects both sides of the head, but in some cases, the pain may only be on the side of your tumor. These headaches tend to get worse or happen more often over time. The pain may be consistent or steady and may not get better after taking pain relievers (like Aspirin, Tylenol, or Advil).
Some of the first signs of a brain tumor may include:
Brain tumor misdiagnosis can commonly be diagnosed as these diseases:
Symptoms of meningioma
The association between brain tumors and personality change is complex and somewhat unknown. Changes such as increased aggression, violence, depression, and suicidality have been observed in those with brain tumors, however many factors may contribute to these changes, making the relationship difficult to delineate.
A brain tumour can cause a change in vision by causing pressure on the optic nerve or by creating swelling of the optic disc in the back of the eye.
Tumors located in the brain can often cause changes in the blood vessels of the eyes, and these changes can be detected during a dilated eye exam.
Patients with high blood pressure can have unusual bends, kinks or tears in the vessels in their eyes. These are typically visible during a dilated eye exam, and can help to give a clear picture of your risk of stroke, aneurysm or other complications.
Screening tests and procedures used to detect and diagnose brain aneurysms include:
