Changes in vision can be associated with brain tumours, they can also be caused by various other conditions.  Any persistent or concerning changes in visions should prompt a thorough medical evaluation by a healthcare professional.

​

Brain tumours can potentially cause various changes in vision due to their impact on the visual pathways or structures within the brain. These changes might include:

​

Blurred Vision

A brain tumour pressing on or affecting the optic nerves or visual pathways can lead to blurred vision or difficulty in focusing.

​

Double Vision (Diplopia)

Tumours affecting the nerves controlling eye movement or those situated near the brain areas responsible for coordinating eye movements can result in double vision.

​

Peripheral Vision Loss

Certain brain tumours can impinge on the areas responsible for peripheral vision, causing a gradual loss of side or peripheral vision.

​

Visual Field Defects

Tumours in specific areas of the brain can create visual field defects, resulting in blind spots or restricted areas in the field of vision.

​

Flashes of Light or Visual Disturbance

Some individuals might experience flashes of lights or other visual disturbances due to the tumour's impact on the brain's visual processing centres.
