Blepharitis is one of the more common diseases of ophthalmology, also called mydriasis, and is an acute inflammatory condition caused by a purulent bacterial infection. The most common bacteria that cause blepharitis are mostly staphylococci, especially Staphylococcus aureus, which is the most common bacteria. Therefore, for the treatment of this disease, topical application of antibiotics is recommended. You can choose sensitive antibiotic eye drops or eye ointment to control the inflammation, such as those currently commonly used in clinical practice including levofloxacin hydrochloride eye drops, tobramycin eye drops, gatifloxacin eye drops, azithromycin eye drops, etc. You can choose any 1-2 kinds. Since eye ointments are more viscous, they are more suitable for use before bedtime. Erythromycin eye ointment, for example, can be applied to the conjunctival sac before going to bed and can exert a continuous anti-inflammatory effect. This disease, if treated promptly, can usually return to normal in 1-2 weeks.
