I have 2 cats in my house, both Ragdolls, age 6-7 months each. The older one of the two has recurring eye discharge which you can see in the images: https://imgur.com/a/NjC5CTF .
First he had this issue with the right eye, after treatment with Aureomycin (chlortetracycline hydrochloride 10mg/g) for 5 days (morning and evening) it passed.
I think at that treatment both cats got treatment for 10 days for herpes as well.
But then it started in the left eye, he had 1 treatment that made it go away for a week, then it came again. Now after the second treatment (of the left eye) it's back again.
I've been to the vet, he gave me the Aureomycin, so before going back to the vet I could use any help to understand what he got and why it keeps getting back.
