Consider it caused by conjunctivitis. The discharge is actually a “corpse” of fibrin and white blood cells secreted by the conjunctiva to wrap up foreign substances or pathogens that cause local inflammation and irritation, which is a way for the eye to protect itself. There are many causes of conjunctivitis, such as “pink eye”, which is mostly caused by infectious viruses, allergic conjunctivitis, which is mainly characterized by itchy eyes, and trachoma, which is caused by Chlamydia trachomatis.
