A bacterial infection can lead to a more serious condition like blepharitis, which is an inflammation at the base of your eyelashes that produces a thick, yellowish pus filled with bacteria-fighting white blood cells. People who are sick with cold or flu tend to have more eye discharge. Discharge is often associated with an eye condition called conjunctivitis. Conjunctivitis may be infectious (caused by a viral or bacterial infection), or sterile (caused by allergy, or some other irritant). When conjunctivitis is caused by an infection, it is commonly referred to as pinkeye.
