A treatise on the diseases of the eye. nce [a], in order to facilitate the approximation of the lateraledges [b b] of the triangle, which should be raised from the subjacent partsby a few incisions with the scalpel. The two lateral incisions of the triangleare to be united by fine sutures, and then the horizontal incision, on eachside of the base of the triangle, is also to be brought together by sutures [asis represented in Fig. 51]. Von Graefe has lately introduced the following method of operating forthe severer cases of ectropium of the lower lid, more especially those whichare the result of chronic blepharo-adenitis. He makes a horizontal incisionjust behind the edge of the lid, in the intermarginal space, from the lowerpunctum to the outer canthus. From the extremities of this line (Fig. 52),two incisions are then to descend vertically down the cheek, for a distance offrom eight lines to ten lines. The square flap A is next to be dissected up,and, if necessary, somewhat raised subcutaneously beyond the lower extremi-. 122 DISEASES OF THE EYELIDS. ties of the vertical incisions. The flap is then to be seized at its upperedge by two pairs of broad forceps, and forcibly stretched upwards, andmaintained in this position by sutures, which are to be applied first at thevertical incisions, commencing at their lower extremity. The two upper angles, which now project considerablyFig. 52. above the upper margin of the opposite edge of the wound, should next be suffi-ciently bevelled off, and this is best doneby making a somewhat bent incision (B B)whose acute angle C is then to be drawnup and united to D. The effect of this bentincision (i> B) is twofold, viz., it shortens theedge of the lid, and elevates the flap. The\b ^ I closer to the edge of the lid the point C is brought, the less does it elevate the flap, butthe more does it shorten the edge of the lid;whereas, the closer the point G lies to the vertical incision, the more is theflap elevated, and the less i
