"Wygodski: Inflammatory glaucoma, 37 cases; improvement, 76 per cent; unimproved, 5 per cent; deterioration, 19 per cent. Sub-acute (chronic inflammatory), 147 cases; improvement 10 per cent; unimproved (condition the same as before iridectomy), 40 per cent; deterioration, 30 per cent; blindness, 20 per cent. Cases operated on at an early stage gave 85 per cent of good results. Simple glaucoma, 104 cases; improvement, O.96 per cent; condition as before, 10.5 per cent; deterioration, 52 per cent; amaurosis, 36.5 per cent. "Hahnloser and Sidler: One hundred seventy-two eyes observed not less than ten years after operation; acute inflammatory, 31 eyes; good results, 64 per cent; relatively good, 13 per cent; blind 23 per cent; chronic inflammatory, 37 eyes; good result, 29.9 per cent; relatively good, 27 per cent; blind, 43 per cent; simple glaucoma, 76 eyes; good results, 42 per cent; relatively good, 28.9 per cent; blind, 28.9 per cent." As far as the _Lagrange procedure_ is concerned, you will remember that after eserinization an oblique incision is made through the sclera by means of a narrow Graefe knife and a large conjunctival flap secured. This is obtained by making a peripheral section of the sclero-corneal margin with the knife and, as soon as the edge of the knife reaches the upper limit of the anterior chamber, it is turned backward and brought out through the sclera obliquely. The conjunctival flap thus formed is turned back over the cornea, and the fragment of sclera that is left attached to the cornea is removed by means of a fine pair of delicate curved scissors. Following this an iridectomy is performed. The conjunctival flap is now replaced and a bandage applied. This operation opens a large filtration passage for the intra-ocular fluids and the prompt healing of the wound with its mucous covering prevents prolapse of the iris. Under no circumstances must iris be left between the lips of the wound. Although Lagrange advocated iridectomy in all cases in his first communication, he no longer judges the procedure to be necessary in all instances, reserving it for cases in which for any reason, such as hypertension, prolapse is to be feared. While Lagrange holds that it is necessary to open the anterior chamber, Bettremieux thinks that a removal of but a portion of the thickness of the sclera suffices. His procedure is as follows: After raising a flap of conjunctiva from the neighborhood of the limbus a medium sized needle, curved and flattened towards its point and firmly grasped in a needle holder, is thrust superficially into the sclera tangentially to the upper edge of the cornea, so as to become fixed in the capsule of the eyeball. A small shaving of the sclera, about 1/2 mm. thick, 11/2 to 2 mm. broad and from 2 to 3 mm. long, is then excised by means of a narrow Graefe knife. The scleral slip is then freed from the conjunctiva at each end and the mucous membrane brought together over the wound by fine catgut sutures.
