Which treatment component is included in Staph Marginal Keratitis management?

• A. Moxifloxacin 0.5% qid
• B. Amoxicillin
• C. Timolol
• D. Prednisolone acetate

Answer: (A)

Staph Marginal Keratitis is driven by Staphylococcus colonization on the eyelid margins that provokes inflammation. The main treatment goal is to reduce that bacterial load on the lid margin, which often governs the course of the keratitis. A topical antibiotic like moxifloxacin 0.5% given four times daily directly targets the eyelid margin bacteria, helping to clear the infection and improve the keratitis. While controlling inflammation is also important, steroids are used selectively and not as the primary initial component, and they must be used with care after bacterial load is addressed. Amoxicillin is a systemic antibiotic not ideal for a localized lid-margin infection, and timolol has no role in this condition.
