A persistent eye discharge indicates the presence of a localized infectious lesion. Common diseases include bacterial conjunctivitis, bacterial keratitis, or lacrimal sacitis, all of which may have this symptom. The first step in the treatment of such diseases is to keep the eyes locally clean to remove the eye secretions in a timely manner, either with saline or 3% boric acid lotion to flush the conjunctival sac. Secondly, to choose sensitive antibiotic drugs to treat. The more commonly used drugs include levofloxacin hydrochloride eye drops, tobramycin eye drops, and gatifloxacin eye drops, any 1-2 kinds can be chosen. If the lacrimal sac is not effective in the case of conservative treatment can be considered surgical treatment, such as lacrimal duct exploration surgery or nasal lacrimal sac anastomosis surgery, this depends on the specific examination of the situation to choose.
