ABSTRACT:
A method and an apparatus for carrying out the method, in which the necessary outflow of the aqueous humor which is continuously being renewed in the eye is ensured, and thus the normal intraocular pressure is maintained. For the treatment, the sclera undergoes operative lamellar incision for partial exposure of Schlemm's canal, and the portion which is opened out is held by a device which is not depicted. A medium is introduced into Schlemm's canal by a tube which is introduced into the circular canal of Schlemm by which the upstream trabecular tissue is hydraulically expanded and traumatically opened at several points and, at the same time, the points are wetted by the highly viscous medium.
