Abstract
The invention relates to a device and method for treating animals, such as humans and dogs, with primary glaucoma by draining or diverting aqueous humor extraocularly comprising a shunt implant wherein the length and tubing of the shunt ensure fluid flow from the eye directly into the frontal sinus cavity via tubing. The device has crossbeam aids in anchoring the device; four slit valves to control fluid flow at required volume; and bulb that anchors in the frontal sinus cavity. The device is preferably made of medical grade radiopaque silicone rubber, and is flexible. Other improvements and a method for implanting the device are disclosed as well.
