Basically the fish's eyes swell up until they eventually explode or the fish dies, or both.
Water quality is usually to blame, but not always. I've heard that often times disease is spread through bad feeder fish you put in the tank.
That sucks. I've been fortunate and never had to deal w/ Popeye. I've had to deal w/ Ich, Columnaris, Swim Bladder Disease, Bent Spine, and Neon Tetra Disease though and what a pain in the ass! My water quality is pristine too, so I agree that there could be other factors that play into why fish get diseases.
