Which additional therapy is listed for Vernal Keratoconjunctivitis if a shield ulcer is present?

• A. Erythromycin ointment qid
• B. Latanoprost
• C. Oral antibiotics
• D. Steroid injection

Answer: (A)

When a shield ulcer is present in Vernal Keratoconjunctivitis, protecting the corneal surface from infection while the inflammation is managed is essential. A topical antibiotic such as erythromycin ointment, applied four times daily, provides direct, local coverage to the cornea, helping the epithelial defect heal and preventing bacterial superinfection that can accompany a shield ulcer.

Latanoprost isn’t used for VKC or corneal ulcers; it’s a glaucoma medication with no role in treating this condition. Oral antibiotics aren’t the preferred approach here because the goal is targeted corneal protection with minimal systemic exposure. A steroid injection isn’t standard for shield ulcers due to risks and the availability of safer, more appropriate topical anti-inflammatory options.
