An Alternative Drainage Surgery for the Toughest Cases
If trabeculectomy cannot be performed, tube shunt procedures usually are effective in lowering IOP.
A shunt is a small plastic tube or valve connected on one end to a reservoir. The shunt is implanted in the eye through a tiny incision. The eye shunt redirects fluid (aqueous humor) to an area beneath your eye. The fluid is then absorbed into the blood vessels. When healed, the reservoir is not easily seen unless you look downward and lift your eyelid.
