Compressive Optic Neuropathy
Symptoms of Compressive Optic Neuropathy
Compressive optic neuropathy from a tumor or mass usually causes slow, painless, progressive loss of vision. It usually affects one eye and typically affects central vision, except for tumors in the pituitary gland, which can compress the optic chiasm (where the optic nerves cross in the brain). If this happens, there is loss of peripheral vision in both eyes.
