Postoperative slit-lamp photographs. (A) Slit-lamp and (B) fluorescein staining images on postoperative day 1; a clear margin of the epithelial defect of the conjunctiva is apparent. (C) Vigorous fibrovascular proliferation of the pterygial tissue is apparent over the previous defective epithelial area. The regrowth extended over the original site of the pterygium within 1 mo after surgery.

Case 3 involved a 65-year-old man whose pterygial excision site showed an epithelial defect on the temporal side of the graft with aggressive regrowth of proliferative tissue over the defect (Figure 1).

Postoperative slit-lamp photographs of case 4. (A) On postoperative day 7, subconjunctival hemorrhage is shown under the graft. (B) Regrowth of the pterygial tissue with newly formed vascularization observed at 3 mo postoperatively.

The reproliferating tissue did not grow over the previous pterygial head margin (Figure 2).
(A) Preoperative slit-lamp photograph of case 14. (B) Postoperative day 6. Dotted line indicates the limbal margin of graft. Tightly adherent unexcised pterygial tissue on the bed can be observed (arrows). (C) Slit-lamp photograph at 8 wk postoperatively. Arrows indicate the recurrent fibrovascular tissue originating from the tightly adherent unexcised pterygial bed and dotted line indicates the limbal margin of the graft.

Fibrous proliferation originated from the tightly adherent unexcised pterygial bed in case 14 (Figure 3).
