Cockatiel with swollen, blind eye -- with blood?

A few weeks ago I noticed that my 14 yr. old cockatiel Gally had a swollen eye. She held it shut most of the time, and when she opened it, it looked glassy, and the pupil was cloudy. Then I realized she didn't seem able to see out of it at all.

I'm not sure what caused it. I don't think she injured it (she lives with two other birds in a large aviary cage). I don't think it could be aspergillosis, as she eats a diet of pellets, cous-cous, fruits & veggies, and we line the grilled-off cage bottom with paper.

I took her to the vet as soon as I could, but they weren't sure what had caused it, or what it was. It wasn't oozing, and she behaves normally -- normal appetite and droppings, no respiratory problems. They gave me "Neomycin and Polymyxin B Sulfates and Dexamethasone Ophthalmic Ointment" to give her 2x a day. When I took her back in after two weeks, she hadn't improved a whole lot, though she was keeping it open more often. They added a once-daily dose of Baytril and upped the ointment to 4x a day.

That was on Thursday. Tonight when I gave her her Baytril, I noticed that her eyelid almost looks like it's pulling up away from her eye, revealing what looks like a dot of blood at the upper corner of her eye. I'm attaching the best pictures I could get of the eye. (The feathers around the eye look sticky from the ointment.)

I would appreciate any thoughts or input on this matter. Is this a new development that I should get her a new appointment for? Is it something the new medication should eventually help?

Thank you so much,
