To secure the same object the neck of thepterygium may be seared with the cautery.—D.] or [Quite similar to Beards operation for pterygium is his operation superficial growths (dermoid, etc.) at the sclero-corneal margin(See Fig. 418)—D 1.

The latter isstripped up and shaved off clean just as in the case of a pterygium (Fig. 417), but, instead of beingsimply shoved aside, is removed in its entirety. There is thus left a raw surface, BACD. The conjunc-tiva above AB and below CD is undermined, and by incisions, AE, CG, BF and DH, concentric withthe cornea, the flaps, EABF and GCDH, are delimited. These are brought together so that AB andCD meet along the dotted line. A stitch or two serve to keep them in place.—D.] V. Operations for Symblepharon 821. Cases of symblepharon anterius are easily cured. We separatethe adhesions between the lid and the eyeball with great care, so as not tocut into the sclera or the tarsus. When the lid has been set free, we mustthen make it our business to prevent a readhesion of the freshly maderaw surfaces, and to make
