Acute conjunctivitis can also be called pink eye. It is an acute inflammatory reaction of the conjunctiva, mainly caused by bacterial infection, commonly by Staphylococcus aureus. The treatment mainly involves local anti-infection treatment, using antibiotic eye drops such as chloramphenicol eye drops, ofloxacin eye drops, or tobramycin eye drops. While using topical antimicrobial drugs, it is important to avoid rubbing the eyes with hands and avoid prolonged use of the eyes.
