Is cup size change from .6 mm to .8 mm in a year rapid deterioration?
Question; if the cup of my optic nerve has expanded from .6 mm to .8 mm in a year, is this rapid deterioration, or slight deterioration? Intuitively it seems like alot of deterioration, but I don't really know how much meaning it has. However, a year ago it was considered on the borderline of normal at .6 mm. After doing a nerve scan the glaucoma specialist thought at the time that it looked most like normal variation.
Yours,
