Stocker's line refers to an iron deposit along the anterior edge of which ocular condition?

Explanation:
Stocker's line is a ferruginous (iron-containing) line that forms on the corneal surface along the anterior edge of a pterygium as it extends onto the cornea. This iron deposition occurs at the advancing, vascularized edge where the pterygium meets the cornea, producing a thin dark line that is a classic sign of pterygium. It helps distinguish pterygium from other conjunctival lesions like pinguecula, which do not invade the cornea or show this iron line, and from conditions like corneal ulcers or conjunctival nevi, which do not produce Stocker's line.
