What causes bacterial conjunctivitis

Bacterial conjunctivitis is conjunctivitis caused by bacterial infection in most cases.

Under normal circumstances, there are bacteria in the conjunctival sac. If the body's resistance decreases or the conjunctival defense ability weakens, bacteria multiply and infect the conjunctiva, which will lead to bacterial conjunctivitis. Common pathogens include Neisseria gonorrhoeae, Staphylococcus aureus, Haemophilus influenzae, etc.

After diagnosis, patients with bacterial conjunctivitis can be treated with antibiotic eye drops or eye ointment locally under the guidance of a doctor, such as erythromycin eye ointment, ofloxacin eye drops, tobramycin eye drops, etc.
