Do you know that brain tumor is one of the more unusual diseases found out through an eye examination. issue of brain tumor shows symptoms like abnormal eye movements, changes to vision, such as blurred or double vision, restricted field of view, and more.
Both benign and malignant tumors are the potential to damage the optic nerves. This damage could make e direct or indirect compressing nerves through increased pressure on the skull. It ends up in several problems with a patient’s vision.
Eye symptoms of a brain tumor
We can observe several latent issues why people show these eye and vision-related symptoms. When any of these symptoms occur, all of a sudden, they could be caused by a blood clot or infections such as encephalitis or meningitis. Following are the symptoms of a brain tumor that need immediate medical advice:
- Blurred or double vision
- Worsening vision
- Abnormal eye movements such as flickering eyes
- The restricted field of vision
- Brief loss, blurring, or “greying out” of eye vision
- Problems when looking upwards or controlling eye movements
- loss of peripheral vision
- blind spots
- Head tilt, when the patient is turning to see things out of the corner of their eye rather than looking straight at them
Seeking medical advice is always good. It could help both your GP and neurologist to investigate such symptoms. So If your doctor suspects the presence of a brain tumor, he will immediately refer you for a scan at a hospital. It will testify to be sure whether or not one is present.
How do brain tumors cause eye problems?
Several patients experience vision problems when a tumor places pressure on a certain area of the brain. We know that the occipital lobe, for instance, is responsible for processing everything that a person sees. So when a tumor in that region of the brain could cause a variety of sight issues. In another case, a tumor affecting the brain stem could result in double vision.
There could be several eye problems when a brain tumor exerts pressure on the optic nerve or when pressure within the skull results in swelling at the back of the eye. Consequently, brain tumors that invade or push on any of the neural connections between the eyes and the occipital lobe end up losing parts of the visual field (blind spots).
Why do brain tumors cause vision changes?
1 Swelling of the optic disc
In this issue, the optic disc in the back of your eye might get bloated due to increased pressure in the skull, causing vision problems.
It could happen for several reasons, but it’s recognized as papilledema when it’s caused by a rise in intracranial pressure (ICP).
2 Pressure on the optic nerve
Healthy brain tissue, including the major cranial nerves, can squeeze by a developing tumor or an accumulation of cerebrospinal fluid (CSF) in the brain.
The pressure that results can affect how effectively the nerves perform, and if the optic nerve is harmed, your eyesight may be affected.
3 Effect of treatment
If radiation is applied near your eyes, you may develop a cataract in the lens of your eye months or even years later.
4 Long-term use of using steroids
We can include it as one of the reasons for an increase in eye pressure (known as ocular hypertension). If left untreated, this can damage vision-critical portions of the eye, leading to glaucoma.
It is a slow but permanent loss of eyesight that starts at the edges of the field of vision and progresses to the center (peripheral vision). As a result, it’s important to visit the optometrist regularly to check for any signs of these complications.
6 Eye Infections and Post Operative Effects
Excessive use of steroids can also result in an increase in eye infections and a delay in repairing the eye’s surface, both of which can cause vision problems.
What types of brain tumors affect vision?
Although orbital tumors develop immediately in the bone socket that holds the eye, and the nerves, muscles, and connective tissues which regulate eye movement, they can cause blindness and other visual disorders. The following are some of the most frequent orbital tumors:
- Tumors of the paranasal sinuses
- Fibrous histiocytomas
- Metastatic cancer
Brain tumors have several shapes and sizes—and so do their symptoms. However, if no definite alternative cause for your symptoms is visible, you should immediately visit a neurologist. If you suspect something is wrong.
Can brain tumors cause eye flashes?
Some kinds of brain tumors can cause visual or auditory disturbances. Problems with vision can include seeing flashing lights, double vision, blurring, and loss of vision.
What could be pressing on my optic nerve?
When a mass (such as a tumor or a build-up of pus or other fluid) grows in the brain and pushes on the optic nerve, it causes eye pressure. It is known as optic nerve compression. It has the risk of causing visual disorders and even blindness.
