**1. Introduction**

The aim of glaucoma surgery is to drain the internal reservoir of aqueous in such a manner that the inside head pressure remains within normal limits.The conventional and alternative pathways have been well known for decades - the anterior route that goes through the canal of Schlemm and the posterior route which is called "uveo-scleral outflow". While the former route has been studied and discussed thoroughly for over a century, the latter mechanism has been discovered only recently and is talked about more as a functional rather than an anatomical entity. When the natural drainage mechanisms get stressed for any reason, the intra ocular pressure rises proportionately. The dearth of knowledge about the involvement of an extensive lymphatic channel system in aqueous drainage, has unwittingly encouraged the surgeons to perform dissections on the sclera with a rather large footprint. Bipolar cau‐ tery is used with impunity for the same reason. We shall now discuss the lymphatic channel system.
