BACKGROUND: A surgical technique has been developed using a Schlemm's canal implant to bypass the obstruction of outflow of the juxtacanalicular trabecular meshwork in patients with primary open-angle glaucoma. The implant device should also bridge healing processes after trabeculotomy and laser techniques. PATIENTS AND METHODS. An 8-15-mm-long silicone tube was implanted in each of two human autopsy eyes connecting the anterior chamber directly with Schlemm's canal. Serial sectioning was performed at two sections of 1-mm length. RESULTS: Implantation of the tube was technically uneventful. Histological examination showed no evidence of mechanical disruption of the endothelial lining of the inner wall of Schlemm's canal. CONCLUSIONS: These preliminary results demonstrate the possibility of shunting aqueous directly into Schlemm's canal using a silicone tube. A clinical study in a selected group of patients is planned. LA: German
