Drug-releasing trabecular implant for glaucoma treatment

摘要

A device and method are provided for improved treatment of elevated intraocular pressure due to glaucoma. A trabecular shunting device is adapted for implantation within the trabecular meshwork of an eye such that aqueous humor flows controllably from the anterior chamber of the eye to Schlemm's canal, bypassing the trabecular meshwork. The trabecular shunting device may utilize a quantity of pharmaceuticals effective in treating glaucoma, which are controllably released from the device into cells of the trabecular meshwork and/or Schlemm's canal. Depending upon the specific treatment contemplated, pharmaceuticals may be utilized in conjunction with the trabecular shunting device such that aqueous flow either increases or decreases as desired. Placement of the trabecular shunting device within the eye, and release of a glaucoma medication therefrom, can arrest or slow the progression of glaucoma.
