My 16 month old baby has a green-yellowish discharge on her eye. what could it be?

Eye infection: Eye infections could be caused by bacterial, fungus or virus and thus have different treatments. You need to take your baby to see a doctor for proper diagnosis/ treatment. Some common eye infections are pink eye , trachoma, blepharitis. Trachoma if not properly treated may lead to blindness. Some eye infections may be contagious (wash hands often), some may last for days or weeks. Take care.
