Which combination therapy option specifies serum used separately from other treatments for corneal ulcers?

• A. Gram +, gram -, anti-fungal, atropine, serum (separate serum from other txs)
• B. Gram +, gram -, atropine, and serum
• C. Two to three anti-proteases may be used
• D. Antibiotics can be fortified

Answer: (A)

Serum therapy provides healing factors that support epithelial regeneration, so it should be used separately from other topical medications to preserve its activity and allow proper cooling, timing, and sterility. The best option reflects a comprehensive approach to corneal ulcers: coverage for both Gram-positive and Gram-negative bacteria to address common infectious agents, addition of an antifungal if fungal risk is present, and the use of atropine to relieve pain and prevent cycloplegia and adhesions. Crucially, the serum is specified as being used separately from the other treatments, ensuring the serum’s bioactive components are delivered without interference from concurrent meds. The other choices either group serum with other drugs or omit the explicit separation, which can compromise the efficacy of serum therapy or rely on less clearly defined strategies.
