A 3-YEAR-OLD girl with bilateral severe congenital glaucoma underwent
an Ahmed valve implantation in the superonasal quadrant of the left eye following
failure of 2 penetrating filtering procedures. Four months later, a second
valve that controlled intraocular pressure (IOP) was placed superotemporally.
Follow-up examination confirmed tubes in contact with the posterior corneal
surface. Eight months after the initial procedure, the superotemporal tube
had eroded, causing moderate conjunctival vasodilation and sterile infiltrate
adjacent to the tube (Figure 1).
During the removal of the tube and plate, a self-sealing wound without leak
and a deep anterior chamber were noted. Five months after shunt removal, the
superonasal tube continued cornea touch without erosion (Figure 2) with an IOP of 18 mm Hg.
