My cat's eye is red, weeping, and third eyelid sore after drops?

Pet's info: Cat | Domestic Shorthair | Male | neutered | 2 years old | 3.5 lbs

Hi, My cats third eyelid has become red and sore looking. His eye was weeping a couple of days ago and I put in some eye drops that I've used b4. Yesterday it seemed like it worked and his eye looked fine, now today its weeping again and the third eyelid looks irritated and red. I'm using the drops again but could there be something more serious wrong?

Poor guy. Since the 1 eye is draining and it also looks irritated, he likely has a corneal scratch or ulcer. He also could have a bout of conjunctivitis which can be allergy related, but that typically affects both eyes and not just one. I am not sure what kind of eye drops you are using; however, most antibiotic eye ointment takes 3-4 days to show improvement. Also you should do the full course of treatment which is 7 consecutive days. If you do not have enough medication, then Chico needs to see your vet for a refill. Also I would recommend checking the expiration date on the medication to make sure it isn't expired! I hope that Chico's eye resolves soon. If he is not improved after the 3-4 day time period or if his eye seems to be getting worse or if you need new medication, then its best to take him in to your vet for further treatment. Best of luck to you both and take care!
