[Operative techniques for surgical treatment of primary and recurrent pterygia].
Surgical treatment of pterygia is indicated when there is a reduction of visual acuity secondary to the development of irregular astigmatism and an (impending) obscuration of the visual axis by the tumor. Poor cosmetic appearance and an insufficient corneal lubrication are more rare indications. The most popular surgical technique in this country appears to be a free conjunctival autograft which, depending on the priority of the surgeon, is combined with adjunctive antimetabolite therapy applied either in primary or recurrent cases. A simultaneous transplantation of conjunctival and limbal stem cell autografts is an excellent method to be considered particularly in cases of recurrent pterygia. In the case of non-existing healthy autologous tissue the resection bed can be covered by preserved amniotic membrane. A lamellar sectorial corneal graft might become necessary if there is a deep corneal defect. The well established technique of suturing the graft has been replaced by fibrin glue in some surgical centers.
