My 15-year-old cat's eye infection won't heal. What's wrong?

By far the most common cause of corneal ulcers is herpesvirus; so although antibiotic drops are usually indicated to treat secondary bacterial infections or prevent infection, Kit might not be improving because she has viral eye disease. Some vets will try oral antiviral medication or topical antiviral drops. Herpesvirus can be very difficult to treat and it never goes away completely. You may want to ask about referral to an ophthalmologist for the best treatment.

I'm not sure if O has seen a vet for his eye infection; if he has not, he has to see one immediately. The eye is such a delicate and important structure that any problem with it should be considered an emergency. Leaving it untreated can lead to vision loss. The vet can prescribe medication to treat O's eye infection and help your parents with administering the medication, as there isn't a spray that can be used for it. Please take him into a vet now.

You will have to use your best judgement on if Binx needs to see the vet tonight or if it can wait, since I am not able to evaluate the eye. If he has chronic eye infections, they may be viral, and the antibiotics may or may not be needed. Helping him keep it clean by using a warm wet washcloth until he sees the vet.

It looks like your cat has a seriously deep corneal ulcer. I cannot suggest any treatment without examining her myself. This probably needs surgery. All you are doing with the Ciplox is preventing infection - that will not heal this. You need to take her to a vet for an exam. In the meantime, I recommend you use an eye ointment (not a liquid drop) on the eye as it will protect the cornea better. https://www.indiamart.com/proddetail/tetracycline-eye-ointment-11084634148.html

Poor Snowball! Since she is still squinting with watery eye discharge after 6 days on Terramycin, you should take her to the vet now. The most common cause of recurrent eye issues and sneezing is due to viral infections (herpesvirus and calicivirus) that can cause both eye and upper respiratory signs when they shed intermittently. Signs typically resolve once the virus is done shedding, but many cats can also develop secondary bacterial infections which require antibiotics for treatment. In the long term, discuss using a Lysine supplement (Viralys is one example) for Snowball with her vet. I hope that all goes well for Snowball!

I would have Junor seen by a vet. This discharge can be indicative of an eye infection, and that requires an antibiotic eye ointment to treat. The eye is such a delicate and important structure that any problem with it should be considered an emergency. That's because leaving it untreated can lead to vision loss. I would take Junor into a vet right away to have his eyes examined and treated.

You are in a very difficult situation with mommy kitty. Most of the time if a cat has discharge it is related to an infection. Most infections need eye drops to resolve. I would try and take mommy kitty into a vet to determine if the eye needs medications. It is possible that maybe oral antibiotics will help with the eye but you will still have to catch her to administer the oral medications. I hope momma kitty starts feeling better soon
