Conjunctivitis is treated based on the cause, primarily with local medication and systemic treatment when necessary, and it is advisable to avoid bandaging the affected eye during the acute phase. First, eye drops are the most basic method of administering medication for treating conjunctivitis. Second, eye ointment should preferably be applied before bedtime. Third, when there is excessive secretion in the conjunctival sac, it is necessary to rinse the conjunctival sac. Fourth, severe conjunctivitis, such as gonococcal conjunctivitis, requires systemic treatment with antibiotics or sulfonamides.
