Compressive Optic Neuropathy
Symptoms and Signs 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. Compression of the optic chiasm causes bilateral loss of peripheral vision (bitemporal hemianopia).
