Eye pain with increased discharge is considered conjunctivitis. The yellowish-white purulent discharge is usually caused by bacterial infection and is related to hand hygiene. The most common pathogens causing purulent discharge are Neisseria gonorrhea and meningococcus, while other pathogens usually cause muco-purulent discharge, which should be treated with antibiotic eye drops and ointment. Ocular discharge manifesting as a watery, viscous discharge may be caused by a viral infection and is treated with antiviral eye drops as well as eye ointment. If the discharge is sticky and filamentous with itching, it may be caused by allergic conjunctivitis, and should be treated with anti-allergic eye drops.
