Stocker's line is most commonly observed in conjunction with which condition?

• A. Pterygium
• B. Pinguecula
• C. Conjunctival nevus
• D. Corneal ulcer

Answer: (A)

Stocker's line is a ferruginous line at the corneal limbus that marks the leading edge of a pterygium. It forms from iron deposition in the corneal epithelium as the fibrovascular pterygium advances onto the cornea. Because this iron-lined streak accompanies the advancing edge of a pterygium and is not a feature of pinguecula, conjunctival nevus, or a corneal ulcer, its presence most strongly indicates pterygium. The line is typically seen at the nasal limbus where pterygia commonly occur.
