What is the follow-up interval after starting treatment for Staph Marginal Keratitis?

• A. 1-2 days
• B. 5-7 days
• C. 2-3 weeks
• D. 4-6 weeks

Answer: (B)

Follow-up after starting treatment for Staph Marginal Keratitis is typically in about five to seven days. This timing lets you reassess the response to lid hygiene measures and topical antibiotic therapy, since improvement in the peripheral corneal infiltrate and symptoms usually becomes evident within that first week. Checking sooner isn’t usually necessary unless pain or vision worsen, while waiting much longer risks missing progression or complications. If there’s no improvement by the end of the first week, reassess adherence, consider adjusting therapy, and evaluate for alternative diagnoses.
