Transcorneal tube extrusion in a child with a Baerveldt glaucoma drainage device.

We describe a clinical scenario in which a child was treated for glaucoma and aqueous misdirection with surgical placement of a tube shunt. The child then suffered extrusion of the tube through the cornea, a rare complication of such procedures. This complication has only been seen in children, and thus, young patients with tube shunts need careful and frequent monitoring, especially during the first year of the post tube shunt period to ensure that they have not developed this complication.
