What is the recommended initial management for Staph marginal keratitis?

• A. Use an antibiotic and steroid drop, along with lid scrubs and warm compresses
• B. Use only oral antibiotics
• C. Use antifungal drops
• D. Observe without treatment

Answer: (A)

Staph marginal keratitis arises from inflammation at the corneal margin driven by lid-margin disease and Staphylococcus on the lashes. The best initial approach is to tackle both the infection and the inflammatory process, while also addressing the lid disease that feeds the problem. Using a topical antibiotic reduces the bacterial load and helps prevent further corneal involvement, while a topical steroid dampens the inflammatory reaction that is causing the margin keratitis. Lid scrubs and warm compresses target blepharitis and meibomian gland dysfunction, decreasing bacterial colonization and improving the lid environment. This combination addresses the infectious component, the inflammatory response, and the underlying lid disease, making it the most effective first step.

Other options don’t fit because they miss one or more essential elements: relying on oral antibiotics alone doesn’t directly treat the local ocular surface inflammation; antifungal drops aren’t indicated for Staphylococcal infection; observing without treatment risks progression of keratitis; and using a steroid without antibacterial coverage could worsen the infection.
