Post Cup to disk ratio

I hope someone knows what this means. I had the MRI on the eyes today as they are concerned with my nerves in the eyes in particular the right. He wrote the cup to disk ration in the left eye is 60%/70% and the right eye is 70% to 80%. He mentioned the normal(my age group)is 40%. I also have optic atrophy and the retina is thinning rapidly since the last test a year ago. My pressure was ok 15/15 in right and 16/15 in the left, which was better than last month at 19/21. so I have the perepheral field later this week and I feel I'll do ok as before. What exactly does this mean anyway the cup to disk ration and what can the future be as far as vision? does anyone know this? My dr really wasn't in today just the tech. If noone knows is there somewhere on the net to find it out?

Since everyone is mute to this question is it possible to get information elsewhere?

Nancy: We can't post URLs on this site.
Typing "cup to disc ratio" or "glaucoma cup to disc ratio" into Google comes up with lots of info.

For example:
"A cup-to-disc ratio is critical when evaluating glaucoma. The cup-to-disc ratio is the amount of the entire nerve head that has been cupped out or where glaucoma has caused damage. Readings range from 0 meaning no cupping at all to 1.0 where the entire optic nerve is cupped out. Many people have some cupping--which is normal. Changes in size of the cup-to-disc ratios or a difference between the two eyes lead the eye care specialist to suspect glaucoma. The cupping of the optic nerve head is directly related to the loss of one's peripheral visual field."

I also read that an increased cup to disc ratio can be caused by something other than glaucoma. The cupping is caused by tissue around the optic nerve head dying. When your doc says 40%, that would be .4 on the o to 1 scale. Similarly 60% or 70% would be .6 and .7.

Hope this helps.
