If the patient’s eyes are red and there is more discharge, and the discharge is sticky, in this case it should be considered that the patient should have conjunctivitis, and it is likely to be bacterial conjunctivitis. Conjunctivitis is the most common clinical eye disease in ophthalmology. Depending on the cause, conjunctivitis can be divided into various types, such as bacterial conjunctivitis, viral conjunctivitis, and allergic conjunctivitis, which are common in clinical practice. When a patient develops bacterial conjunctivitis, there is a foreign body sensation in the eye, and the conjunctiva becomes congested, meaning that the eye is red and there is a large amount of mucopurulent discharge. Clinical treatment of acute bacterial conjunctivitis is mainly topical treatment with effective and sensitive antibiotic eye drops and appropriate antibiotic eye ointment at bedtime. In general, with topical medication, the patient’s conjunctivitis can be cured and the redness of the eyes and the discharge can be eliminated.
