My Rabbits Eye, Can anyone assist?

I was told yesterday my rabbit most likely has a tumor and shes completely blind in her eye and has rapid weight loss. They found mass behind her eye (leading to diagnosis of tumor) and shes on three different medications to try prevent operation. Her eye is completely damaged, fully white, with broken blood vessels, blood veins and also the bottom of her eye has a pink lump in it.. but flat if that makes sense? This lump was smaller yesterday, its gotten a lot bigger.... any suggestions? Should I be worried this is getting bigger? She's due vet on Wednesday to monitor weight loss.. and pain.. should I be taking her sooner??

Because tumors can cause unpredictable results and problems, the best thing to do would be to ring your vet to find out if this is a problem that would require you to bring your bun to the vet before Wed.

Ok thank you, I will do that in the morning
