Erythromycin ointment should not be used for wheals. This is because the ointment is more concentrated than the eye ointment, which can irritate the conjunctival sac of the eye, and the dosage form is not suitable for use inside the conjunctival sac of the eye. When you have granuloma, you must give regular treatment. First of all, local hot compresses, you can use hot towel paste or hot water fumigation, each 15-20 minutes, 2-3 times a day. Topical dabs of antimicrobial eye drops 4 times a day and eye ointment before bedtime to facilitate the antimicrobials to stay in the eyes for a longer period of time. Oral antibiotics can be given for severe symptoms, and when localized abscesses form and pus heads appear, they can be incised and drained. Do not squeeze before maturity, otherwise the spread of inflammation can cause orbital cellulitis, further development causes sepsis.
