That's good on the first part. On the second part, if there's no change, no worries, right? Eyes are weird and they can have benign conditions which can make even experts think there's a problem.
My eyes are very different from each other, and something showed up on the conventional test which made the optometrist think I had glaucoma, but when she had me come back and tested with the laser machine, everything checks out and is within the range they should be with both eyes considering my age.
One of mine has a nice wad of nerves right at the center like it should be, while the other is very sparse. But it's the healthier one which seems to have a dead spot - go figure. She says everything she sees I was probably born with and not anything that happened later.
