Which tests are used in evaluating Staph Marginal Keratitis?

• A. NaFl staining
• B. A-Seg photo
• C. Lid eversion (styes, telangiectasia, blepharitis)
• D. All of the above

Answer: (D)

Staph Marginal Keratitis is driven by lid margin disease with staphylococcal involvement that affects the corneal periphery, so evaluation needs both corneal and lid findings. Fluorescein staining shows any corneal epithelial disruption and marginal infiltrates, giving a direct view of the keratitis extent near the lid margin. Anterior segment photography provides documentation of the keratitis’ size and location and helps track changes over time. Lid eversion reveals the lid margin condition—styes, telangiectasia, and blepharitis—which are commonly present and contribute to the inflammatory environment causing the keratitis. Putting these together gives a complete assessment, so all of these tests are appropriate in evaluating Staph Marginal Keratitis.
