Occipital lobe (and glioma)
The occipital lobe processes vision; gliomas here can affect sight and visual perception.
In short: Occipital lobe (and glioma)
- It processes vision.
- It is at the back of the brain.
- Gliomas here can affect sight and visual fields.
- It is a less common glioma location than other lobes.
What it is
The occipital lobe is the part of each cerebral hemisphere at the back of the brain, responsible for processing vision. Gliomas in the occipital lobe can affect sight and visual perception, depending on the exact location.
Understanding Occipital lobe (and glioma)
The occipital lobe contains the visual cortex, which processes the signals from the eyes to produce sight. A glioma here can cause visual symptoms — such as loss of part of the visual field (for example, difficulty seeing to one side), visual distortions, or, less commonly, visual hallucinations or seizures with visual features. Because vision from each side of space is processed by the opposite occipital lobe, the pattern of visual loss can reflect the tumor's location. The occipital lobe is a less common location for gliomas than the frontal or temporal lobes. Understanding occipital lobe gliomas clarifies how tumors here can affect vision and why the pattern of visual symptoms relates to the tumor's location. Surgical planning considers preserving as much vision as possible. Understanding occipital lobe gliomas clarifies their typical visual effects.
Why it matters
Understanding occipital lobe gliomas helps patients and families see how tumors here can affect vision — and why the pattern of visual symptoms relates to the tumor's location.
Common questions
What does the occipital lobe process?
Vision.
What can an occipital glioma affect?
Sight and the visual fields.
Is it a common glioma location?
It is less common than the frontal or temporal lobes.
Bottom line
The occipital lobe processes vision; gliomas here can affect sight and visual fields, and the pattern of visual loss relates to the tumor's location.
