Abstract
Goniotomy became the procedure of choice for primary congenital glaucoma (PCG) when Otto Barkan reported on its surgical success in 1942, and PCG remains the most common indication for goniotomy as of this writing. This chapter reviews the indications for surgery, preoperative preparation, operative technique, postoperative management, complications, and results of goniotomy. Its goal is to describe the position of goniotomy in the current surgical armamentarium of procedures for glaucoma. It is not intended to replace direct, personal training for individuals who want to perform the procedure.
