Brain tumours are masses of abnormal cell growth within the brain. These growths usually spread rapidly from the brain to the nerves, tissues, and organs around the brain, thus leading to a mental and physical breakdown in the health of the affected individual. This can lead to vision problems, such as sensitivity to light, blurred vision, abnormal eye movements, double vision, and loss of vision. These symptoms are sometimes the very first sign of a brain tumour and should not be taken lightly.

Vision problems can set in when a tumour places pressure on certain parts of the brain, such as the part of the brain that processes whatever a person sees. A tumour growing in that section of the brain can cause different eyesight problems such as double vision, dizziness and vertigo. Also, when a brain tumour exerts pressure within the skull, it causes the back of the eye (the optic disc) to swell, leading to severe eye problems and even blindness. The vision loss often begins with blurry or double vision. As the tumour grows bigger, it compresses the optic nerve more and more, damaging the nerve until he/she becomes completely blind. To prevent this, report any form of vision problems to your optometrist or primary care doctor.

Brain tumours are commonly treated via surgery, chemotherapy or radiotherapy. Surgery involves the removal of every trace of the tumour by a neurosurgeon. After the surgery, it may be necessary to give radiotherapy or/and chemotherapy. it usually takes between one to four months for a patient’s vision to repair itself. However, if the tumour has done significant damage to the nerves of the eyes or has stayed for a long time, the vision may never be as before. Hence the importance of early detection.
