Ointment alone may cure it (from the vet) fusilthalmic (little orange tube). However go and see the vet anyway. I used the Fusi ointment on one of mine as I had some in and it wasnt the correct treatment for that particular ailment. Mine had an ulcerated eye and ended up having to have it took out completely So I wouldnt just put anything in, go to your vets and get advice first
