What is an alternative cause of the pus in my eye, rather than pink eye?

Justin S asked:


I wake up every morning and both of my eyes are coated in a very large amount of yellow pus. I clean them out, and then my eyes will gather build ups throughout the day, usually starting at the very tops of my upper eyelid, and then when it comes down to the corners of my eyes, I am able to clean it out. I’ve tried multiple medications for pink eye and other such antibiotics to no avail. I am able to see an eye doctor in about 3 weeks, but until then I was wondering what else could be the cause of this. To the best of my knowledge, it’s not an allergic reaction, and it doesn’t seem to be any better or any worse depending on my surroundings or anything like that. Just steady pus production in the upper part of my eyes, and after sleeping, I can see just how much is made in 6-8 hours.
