1. PRINCIPLES OF NONPENETRATING GLAUCOMA SURGERY
Nonpenetrating glaucoma surgery (NPGS) selectively targets the pathological structures
responsible for the increase in intraocular pressure (IOP) (1,2). This is done without
penetration into the eye (3). In this respect, NPGS is essentially extraocular surgery as
opposed to other surgical modalities that necessitate eye penetration. The avoidance of
penetration into the eye reduces the risk of hypotony and its sequelae.
