I see. In the case of cupping, isn't it that one can measure
the cup-to-disc ratio by noting how big is the optic disk and
the cupping. So what do you mean measuring cupping in particular?

Is there any chance (even 0.01%) or no matter how tiny as it may seem
that the laser can damage the rods and cones.

Also it is possible to scan the entire retinal surface from the
macula to optic disk to peripheral portions in one sitting. How
long would this take?

Tnx.
