Just got back from Buddy's appointment with his eye doctor (this cat has more doctors than I do! LOL) I was right in thinking that his eye looked bigger again. The vet confirmed that the pressure was back up. He still doesn't know for sure what's causing it, but he's so surprised that Buddy still has vision in the eye. He said the pressure must have increased slowly so as not to damage the nerves. I asked if there was anything else that could be done and he said that eye surgery on cats usually wasn't very successful. Dr. Hermann said to continue the pills and the eye stuff and gave me drops to give twice a day. Whew!! We go back in three weeks for another recheck. I have to add that Buddy was sooo good. Having someone look in your eyes will all sorts of devices would be disconcerting to me.
I'll do an update after the next vet visit unless something comes up beforehand.
