Abstract

A method is described for creating a shunt between the anterior chamber and a vortex vein. This procedure increases the outflow facility of aqueous humor and reduces intraocular pressure in the normal pigmented rabbit. The average value for outflow facility was 0.27 µl per minute per millimeter of mercury prior to operation and 0.43 µl per minute per millimeter of mercury after the operation. The statistical difference between preoperative and postoperative values for average intraocular pressure and outflow facility ivas significant. It is essential to maintain the plastic capillary tube in the lumen of the vein in order to keep the shunt functioning and to minimize postoperative complications.
