Transcorneal tube erosion of an Ahmed valve implant in a child
Al-Torback A; Edward DPAmerican Journal of Ophthalmology 2001; 119:
A three-year-old girl with bilateral severe congenital glaucoma underwent Ahmed valve implantation in the superonasal quadrant of the left eye following failure of two 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. During 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 with an IOP of 18 mmHg.
