What is An Optic Chiasm Glioma?
The wires joining each eye to the brain are called the optic nerves. The optic nerves join about half way between the eye and brain, and then split up again. The join is called the optic chiasm. A Glioma is a benign tumour of nerve tissue. A tumour is a condition where a part of the body grows more than it would normally. Benign means that bits of the tumour will not normally break off and spread to other parts of the body. It may, with time however grow and get bigger. The optic chiasm is made of nerve tissue. If such a tumour affects the Optic Chiasm then it is called an Optic Chiasm Glioma. These tumours are usually solid but may be cystic.
