Any ideas what this could be?

My 11 year old cat has had issues over the last 6 months or so with her left ear. At first the vet thought it was Pallups but when he went in during surgery to remove it he founds hundreds of little cysts and popped as many as possible but said it was going to be an ongoing issue and they would come back. Sure enough a month later her ear was nasty again with a terrible odor. He prescribed a strong 7 day medication and it cleared up but a couple weeks later now it's starting to look yucky again and now in addition to that her left eye (same side of the head as bad ear) is messed up. The pupil won't dilate and the eye looks cloudy and she is keeping it shut or half shut most of the time. She is also not eating well and has been staying under my sons bed most of the day. I tried to give her a couple treats today under the bed she wasn't interested (so unlike her) and I noticed she was also drooling. Are these all bad signs of maybe just related to her ear problem? We have an appointment for tomorrow evening but just wondering if anyone has any experience with these symptoms? Worried about my girl!!

A few pics of her above you can sort of see in the first pic the pupil difference. She never goes under the stools like that either she has been hiding a lot like that

Does she have any balance issues?  I ask because my boy had been diagnosed with 'vestibular disorder' based on the basis that one pupil was larger than the other.  Our case had a happy ending, in that a two week antibiotic shot cleared up our boy's problem.  For the details, here is that thread:

Meanwhile, here come some prayers and positive vibes your way. 

Thanks, she doesn't seem to have a balance issue, she's walking normal and able to jump up on the couch and beds fine. I have a feeling it's related to her ear problem but not sure. We got her 11 years ago as a kitten who was born to a barn cat. When we got her she has fleas, worms, ear mites, and ring worm. We got it all cleared up and she's been an awesome cat. We have another cat about the same age we adopted at 4 months old from the humane society and he has not had any health problems.

When you do see the vet, I would mention this possibility--just in case.  Your vet may not have heard of this problem.

I definitely will, we go tomorrow at 5:40pm. I will post an update.

Looking at her eye, I am wondering about the possibility of Horner's Syndrome (signs include small pupil size, drooping of the upper eyelid, sunken appearance to the affected eye, and elevation of the third eyelid). Horner's syndrome can be caused by a number of different things, including middle ear disease (such as an infection or tumor)... so definitely could be related to her ear issues.

A few years ago, one of my cats developed chronic/recurrent right-sided ear infections due to a mass in his middle ear that was obstructing the ear canal. (You could also see this in a cat with a large number of cysts narrowing the canal.) We ended up having the affected canal surgically removed.

Will be thinking of you guys tomorrow... let us know how things go.  

Smudgie Does have Horner's syndrome. It's caused by her inner ear issues. He gave her a shot of antibiotic and an anti-inflammatory medicine also by injection. He said to use the medicine once a day in her ear also and I have to bring her back next week on Tuesday. If she continues to have issues with her ear like this he might have to remove her entire ear canal and she might be deaf in one ear. For now he wants to try this less invasive method. You got the nail right on the head 4fabfelines!!! Thanks! I will update next week. I have a feeling she may end up needing the war canal removed this ear issue has been ongoing.
