Do you agree that a classic arcuate scotoma always signals that the flow of blood or nutrients to the optic nerve has been interrupted at some point in some way?
I don’t agree. A classic arcuate scotoma is seen frequently in glaucoma; I think only a nasal defect is more common. There are competing theories as to why glaucoma damage occurs. One theory assumes the damage to be mechanical, while another assumes at least a component of blood flow disturbance. The common pathway for all involves ganglion cell death in a specific location.
