Pterygium is a fibrovascular proliferative disorder in which conjunctival tissue grows medially to cover the clear cornea. It is well known that outdoor work in situations with high light reflectivity enhances pterygium development. Surgical resection is not always necessary for patients without visual disturbance or cosmetic complaint. A 63yearold woman presented with a 5year history of a slow growing wingshaped ocular surface lesion in the left eye. Her best corrected visual acuity was 1.2 in the right eye and .9 in the left eye. On slitlamp examination showed marked pterygium that extend from the nasal side of bulbar conjunctiva onto the cornea in the left eye. A vertical gold leaflike line was also detected at the head of pterygium (Figure 1 arrow). Inferior conjunctival autograft transplantation was performed. One year after the surgery, there was no evidence of recurrence (Figure 2). Her left visual acuity improved to 1.2. A vertical line at the head of pterygium has been termed Stocker’s line.1–4 The lesion consisted of corneal linear iron deposition.3,4 Several
