SEAL stands for which term?

• A. Subepithelial Arcuate Lesion
• B. Superior Epithelial Arcuate Lesion
• C. Superior Posterior Arcuate Lesion
• D. Superior Epithelial Arcuate Lesion

Answer: (D)

SEAL identifies a specific corneal finding in contact lens wearers: a crescent-shaped defect in the superior part of the corneal epithelium. The name packs the meaning: Superior indicates the location at the top of the cornea, Epithelial tells you the lesion involves the corneal epithelium, Arcuate describes the arc-shaped arc of the defect, and Lesion just names the abnormal area. So the term expands to Superior Epithelial Arcuate Lesion. This is distinct from subepithelial or posterior lesions—the former would be beneath the epithelial layer, not on it, and the latter would imply a posterior corneal location—neither of which match the SEAL wording. In practice, recognizing the epithelial, superior, arcuate nature helps differentiate SEAL from other contour or staining patterns seen with lens wear.
