Persistent eye infections

Hi everyone, I’m new to the community and was wondering if anyone could help me out. My Single chin Roo is 7years old. Up until this year she has had 0 health problems. I have had her in the vets office 4 times in the last 6 months for persistent eye infections. I have followed through with every antibiotic and also switched from paper bedding to fleece cage liners. It seems that no matter what I do her eye infections are coming back! Is there a possibility that she can be allergic to her...
