Does my cat have glaucoma?

About 2 weeks ago, I started noticing that Mietzi's right pupil would always stay quite large, even when the left one was narrowed. She never paws at her eye or acts like she is experiencing discomfort. She is eating, pooping, peeing, sleeping, all normal. The white part around the eye is also red and veined. I went online and read about glaucoma and anisocoria and decided to take her to the vet. There is an American vet on base but they are always busy so last night, I took her to a German vet. He took blood and sent it away for a full scan. He tested the pressure in that eye (several times) and told me that while it should be around 25, it is at 80. Then he put some drops in her eye, waited 30 min, and tested again. The pressure was 50. He gave me a prescription which I picked up and it calls for 1 drop in the eye 2X a day. He wants to see her again on Monday, but talked about all the many things it could be and if it should get painful, the eye might need to be removed. It isn't that I don't trust him, but his bedside manner left something to be desired and I would just love to hear if you would treat this any other way...or if there is something I should try that I'm not. It was somewhat traumatic for me because on the way home, she was foaming at the mouth and throwing up. Did the medicine cause that or the stress -- and why did I leave the name of the meds at home?? Thanks for your time! :)

Good morning, Dr. Marie!

Thanks for your response! I still don't know the name of the medication (it is in German anyway :/) but I have put one drop in her eye morning and night since Friday. The good news is, and I don't believe it is just hopeful imagination on my part, her eye seems to be responding and there was one time this weekend where the pupil definitely contracted and became almost as small as the other eye...

So, because I think of glaucoma in humans as irreversible, have you ever treated a cat which appeared to have glaucoma but then the eye recovered? Is that even possible?

I promise, no more questions :)

Thank you for your time!
