摘　　要：AIM:To introduce a novel surgical technique using a Z-shaped incision without epithelial resection in ophthalmic pterygia.METHODS:This was a prospective study.During pterygium surgery,all proliferative tissues were separated from the cornea and conjunctiva without resection of the tissues.The unaffected conjunctiva was incised in a Z-shape.The upper(or lower)conjunctival flap was sutured to the lower(or upper)normal conjunctiva on the limbal sclera,while the proliferative tissue was sutured to the upper conjunctiva(or lower)near the fornix.RESULTS:Ten patients with pterygia were eligible for this study.Eight patients with primary pterygia and 2 with recurrent pterygia were included.The age of patients at surgery ranged from 47 to 90y(average:71.9y).Five patients each showed right and left-sided pterygia.The postoperative follow-up periods were from 8 to 78mo(average:25.0mo).The surgery was successfully conducted and wounds were favorably reconstructed in all patients.The proliferative tissues sutured to the normal conjunctiva showed palor and attenuated neovessles,and never showed re-growth after surgery.Nine patients did not show recerrence.Recerrent pterygium was noted in 1 patient,but additional treatments were not required.CONCLUSION:The procedure involves the reconstruction of pterygial tissue and normal conjunctiva using a Z-shaped incision.The scleral limbal wound can be covered with nonaffected conjunctiva without any excision of conjunctival epithelia in patients with primary or recurrent pterygia.
