If Staph marginal keratitis recurs, what long-term therapy may be considered?

• A. Low-dose oral antibiotic long term
• B. High-dose topical steroids long term
• C. Surgical eyelid repair
• D. No further therapy

Answer: (A)

Managing recurrent Staphylococcal marginal keratitis focuses on controlling lid-margin blepharitis and the Staphylococcus colonization that fuels episodes. Using a low-dose oral antibiotic long term helps reduce the bacterial load on the eyelids and dampens the inflammatory cycle that leads to keratitis, breaking the pattern of recurrences. Doxycycline is a commonly used example due to its anti-inflammatory properties as well as its antibacterial effects, and the idea is to maintain a gentle suppression rather than high-dose treatment. Long-term topical steroids, while they may reduce inflammation short-term, carry risks with prolonged use and do not address the underlying bacterial source. Surgical eyelid repair targets structural issues rather than infection control and isn’t the primary strategy for recurrent infectious keratitis. Opting for no further therapy would leave the cycle of blepharitis and keratitis unchecked.
