I tried apple cider vinegar and colloidal silver and both helped but the infection kept coming back. I couldn't afford $200 the vet wanted so out of desperation I decided to use my leftover antibiotic capsule (Amoxicillian). My sister who is a nurse used my cats weight times 5 mg. antibiotic per pound and figured that a 500 mg. capsule could be divided into 16 dosages. From information I read about, I gave my cat one dosage a day for 10 days and we are now 7 days off the amoxicillian and there is no sign of the infection coming back. You can tell that it is still healing as there is crusty stuff, like scabbing still coming out of his eyes. I am glad I used the antibiotic. This cat is a stray that just showed up in my yard one day and he is a delight. Lastly, I must say I am very angry that I can't afford to go to a vet. Everything is outragious. Thanks to everyone who has contributed to this sight.
