Neither of those eyes look anything like any stuck eyecaps I've ever seen. Even if a couple of them are stacked up, they are still clear with little jagged edges around them.
I'm glad you have a good vet in your area. Please keep us updated on your snake's diagnosis and prognosis!
I'll add one more thing...while it would totally suck, no doubt, I have heard of many cases of rescued ball pythons that were blind, but once rescued lived lives as contented as we can imagine these animals' lives to be. Sight isn't their primary sense...and they don't have to ever go hunting for their prey or hide from predators....they can live just fine in captivity, even if blind. I've also seen cases of some pretty nasty looking eye issues eventually healing up to perfectly normal eyes. Hang in there....and good luck!!
