Honestly, I don't know about the cataracts and PRA, but what I do know is that, with glaucoma, once the pressures are starting to spike up into the high 60's and 70's you won't be able to control them for long. What we experienced is that a particular medication would work for a short time (days or weeks) then lose effectiveness, and we'd have to add another kind of drop and then another and another. With our girl, for the first eye it was about 4 or 5 months from dx of glaucoma until she had to have the eye removed. Her optic nerve was already destroyed anyway from the glaucoma so she had no vision left in that eye. And she was in pain. A year later, glaucoma hit her other eye. We knew she was not a surgical candidate at that point as she has chronic bronchitis so we would have to do the chemical ablation. Once the pressures are spiking high, ablation isn't an option, so we fought it with the drops for maybe three months, then threw in the towel and had the procedure done. She still had some very slight vision left at that point but her pressures were spiking into the sixties and we knew she was in pain, so we sacrificed the little vision she had left and just did it. Dogs are stoic and often don't show their pain, but your vet should have explained to you that glaucoma is very painful - like having a severe migraine times ten - and a pressure spike near 70 is going to cause pain. Give Sophie some snuggles and belly rubs from us. I bet she's quite a cutie. Good luck with her. I hope you are able to find her a forever home.
