TECHNIQUE OF LAMELLAR SCLERAL RESECTION* BY

Abstract

THE purpose of this paper is to describe certain points in the technique of lamellar scleral resection which I think help in its efficient performance and shorten the time spent upon it. Particular mention is made of the scleral marker, the suture-retention coil, and the suture-tying forceps, new instru-ments which I have designed to assist in the orderly conduct of the operation. The time taken for a half-circumference resection of a scleral strip 28 mm. long is 45-55 minutes. The resection of a strip 45 mm. long which necessitated the division of three extra-ocular muscles for adequate exposure took 73 minutes. TECHNICAL POINTS IN THE OPERATION HAEMOSTASIS.-Oozing of blood is much reduced by injecting 0.5 ml. saline with adrenaline chloride 1:1000 one minim into Tenon's capsule in each quadrant for resection, that is 1 ml. with 2 minims adrenaline when half the scleral circumference is marked for lamellar resection.
