Molteno® Implants were developed for the treatment of
severe and complex cases of glaucoma. The implants consist
of a fine bore silicone tube opening onto the upper surface
of one or more episcleral plates. The function of the tube
is to deliver aqueous from within the eye onto the upper surface
of the episcleral plate. The episcleral plate is firmly sutured
to the sclera and covered by a thick flap of Tenon's tissue
and conjunctiva. The function of the plate is to initiate
the formation of a large circular bleb which develops a specialised
fibrovascular bleb lining and becomes distended by aqueous.
It is this fibrovascular bleb lining which is responsible
for regulating the escape of aqueous from the eye and which
determines the final level of intraocular pressure (IOP) that
is achieved after insertion of the implant.
