How is angular blepharitis treated?

Lid margin ulcers may be caused by angular blepharitis, allergic blepharitis, keratitis, and other factors. It is important to seek prompt medical attention at a hospital to determine the underlying cause and receive appropriate treatment under a doctor's guidance.

1. Angular Blepharitis:

This condition often affects both eyes and primarily occurs at the outer canthus. It may lead to symptoms such as redness, swelling, erosion, and maceration of the eyelid margin and surrounding skin at the outer corner of the eye. Adjacent conjunctiva may become congested, sometimes accompanied by follicular conjunctivitis, and punctate keratitis may also develop. Under medical guidance, antibiotic eye ointments such as erythromycin ointment, chlortetracycline ointment, or gentamicin ointment may be applied for treatment.

2. Allergic Blepharitis:

This typically occurs when patients come into contact with allergens, triggering an allergic reaction in the eyes, resulting in symptoms such as redness, swelling, and increased eye discharge. In severe cases, it may even lead to lid margin ulceration. Under medical supervision, anti-allergy eye drops such as sodium cromoglicate eye drops, emedastine difumarate eye drops, or dexamethasone sodium phosphate eye drops may be used for treatment.

3. Keratitis:

Keratitis refers to inflammation of the cornea that occurs when its defensive capacity is reduced and is invaded by exogenous or endogenous pathogenic factors. Patients may experience discomfort such as eye pain, photophobia, and excessive tearing. Under a doctor’s direction, anti-inflammatory medications such as tobramycin eye drops, erythromycin ointment, or levofloxacin eye drops may be used for treatment.

In addition, conjunctivitis may also cause symptoms resembling lid margin ulcers. It is important to promptly visit a hospital for thorough evaluation and, based on the specific cause and severity of the condition, receive appropriate treatment under medical guidance.
