Patch protects from more UV light and other irritation... plus, it gets the thing out of sight of the owner (lol).
ANYTHING you squirt in the eye - whether it's oil- or water-based - will be washed out by normal tear action within 10 minutes or so... probably even faster with the increased tearing that goes along with pinkeye. That said, I do commonly squirt some mastitis meds in there if I've got a tube on hand when I'm treating one.
I still think Vetericyn pinkeye stuff is total BS... it's very(expensive) dilute bleach water (99.836% water!)... not gonna hurt anything, but about all I can see it's doing is flushing the eye... and maybe just stimulating more tearing because you're bugging the animal squirting it in it's eye...
Treating with a systemic antimicrobial, like long-acting tetracyclines(LA-200/300) or Draxxin, which will be present in the tear film at the same concentration as blood/tissue fluids, essentially 'bathes' the eye in a constant therapeutic dose of the antibiotic.
I used to do the subconjunctival penicillin/steroid injections back in the day - in conjunction with LA-200 and a patch or sewing the lids shut - but I'm not convinced that (actually, I'm fairly certain that it's NOT effective) it is helpful.
Once the needle prick seals up and the antibiotic stops leaking out... which occurs within just a few minutes... that bleb of a couple of milliliters of penicillin will be no more effective than if you'd stuck it in the back end of the cow...and a 2-3cc dose of penicillin in a 1000-lb animal is NOTHING.
Vaccination... I'm not convinced that it's effective... commercial or autogenous... if you think it's helping in your herd, who am I to tell you not to do it?
