Abstract: A alteration caused in a nerve fiber layer could not accurately be displayed. There is provided a tomographic imaging apparatus including a generation means for generating a nerve fiber bundle map, a designation means for designating an arbitrary nerve fiber bundle in the nerve fiber bundle map, and a display control means for causing display means to display a parameter of the designated nerve fiber bundle.

Abstract: A drainage implant for draining chamber water from the eye, comprising a tube-shaped part (1) which has at least one lumen, whose open distal end (3) can be introduced into an episcleral vein and whose open proximal end (2) can be introduced into the front eye chamber for draining the chamber. The proximal and center areas of the tube are covered with silicon. Said covering is embodied in the center area in the form of a plate (6) with eyelets (6) in order to stabilize and fix the implant by means of sutures on the sclera. The implant contains a guide wire (8) inside the tube (1), the front of said guide wire being acutely sharpened. The guide wire is used to puncture the vein and also stabilizes the very thin tube (1) for implantation.

Abstract: The invention relates to an implant for draining the aqueous humour from the anterior aqueous chamber of the eye into Schlemm's canal. Said implant comprises a tubular proximal part (1) with at least one lumen, whose open end (2, 3) can be introduced into the anterior aqueous chamber for draining the aqueous humour and a tubular distal part (5) that is open at both ends (6) and that has at least one lumen connected to the proximal part (1) to form a substantially T-shaped implant, whereby said distal part (5) can be introduced into Schlemm's canal. To produce an implant of this type, which can be securely fixed, at least one plate-shaped fixing element (7) is provided, said element stabilising the implant on the sclera. The fixing element is connected by the central section to the distal part (5) on the opposite side of the latter to the proximal part (1) and comprises at least one eyelet (8) or similar for fixing with a suture.
