5 year old Persian seems to have an eye infection, but not?

She is 5 today and what a horrible way to have a birthday. I noticed a couple days ago the fur in the outside corner of one eye was gone and I was concerned then, but just kept an eye on her. Last night I cleaned her eye because like all persians she had goo in the corner, usual color and she let me because she has always loved that. This morning it was more of a red color and a lot of it. Again, let me clean it, purring the whole time. When she was little she was diagnosed with fungus in her ears which simply causes her to itch from time to time, it has been under control. This morning though as I was getting the cloth ready to clean her eye I saw her digging her ear, so after cleaning her eye I cleaned a little gunk out of her ear (same side as the problem eye), but it wasn't nearly as bad as it has been in the past. I am going to say she is still being her normal self, we live in the South of France so it is hot and she tends to lay low on these 90° days. It was weird last night when I saw her sleeping in the bathroom on the floor, she never does that and when she was in there this morning I found a moth on the window so she may have just been on a mission haha. When she does her blinking at me, the "bad" eye doesn't close as much, and I think it was 2 days ago I saw her bathing and she left that eye closed. This was just before I found the missing fur and helped her open her eye to see if she had a hair on it or something (common) and that is when I saw the missing fur next to her eye.

I say "infection, but not" because it isn't swollen, no pus, it doesn't hurt her when I touch it and other than laying low for the heat she does seem to be her normal quirky self. I have told my husband if it doesn't seem better today we're going to the Vet, so no worries, that IS the plan ;-) I just want to know if anyone else with a Persian (or another cat or course) went thru something like this and what it ended up being.

Another quick background, she is strictly indoor except for the occasion dash out the kitchen door, but that has not happened in well over a week. She did however, and I don't remember the day, but recently she got over to my mother in law's side of the house, which is under major construction aka playground for a curious cat. Furniture everywhere, dust bunnies, you name it- and that is where the flea ridden dog lives (I have checked her several times for fleas because she did get them from the dog in their first encounter a couple months ago, I have not found any this time). She was over there for a couple hours before we found her, happy as can be going under things and exploring. I am thinking she may have gotten something in her eye over there (and the dust aggravated her ear), sound possible? I keep thinking she looks sad, but it is just her eye doing a slow leak I guess. She has been bathing normally, sleeping 23 hours like a normal cat (hehe), this morning she played with a piece of grass before it got too hot, I just saw her eating and drinking, and as far as I can tell the litter is being used (pregnant, can't investigate too closely).

Any ideas what this could be? Again, taking her to the Vet soon if this doesn't get better with what I have started doing today.

Thanks :-)
