Safar's method aims at getting discrete areas of coagulation in the choroid without any injury to the retina. Larson produces areas of coagulation by surface cauterization with a small, ball-shaped electrode. Weve uses Larson's method, and also the encircling method with a fine needle.The advantages of Safar's method are: (a) The exact placing of the area of coagulation; (b) the possibility of using a more regular current; (c) less likelihood of the area of coagulation being too extensive; (d) the possibility of making large barrages without losing fluid and the eye becoming soft; (e) the avoidance of having to make a subsequent puncture to draw off the subretinal fluid.Technique.-(1) Nearly the same as Guist's encircling method or the formation of barrages. (2) INSTRUMENTS: Special isolated needles to avoid sparking and also to limit the depth of entry. Special ivory-headed retractors; glass retractors are also useful.Treatment.-(1) Previous to operation: rest in bed, with the use of Lindner's Lochbrille. (2) Subsequent to operation: eight to fourteen days with both eyes bandaged. Wearing of the Lochbrille after the bandages have been removed.Scars.-Ideal scars about the size of optic disc, round, and stippled with small spots of pigment; the retina lies flat over these scars as seen by tracing the retinal vessels.Results. Up to 1932 (Safar's).-Thirty-nine unselected cases: twenty-four reattachments, that is, more than 60% in recent cases of myopia, and after contusion more than 90%.
