Transcorneal tube erosion of an ahmed valve implant in an adult.

Al-Shahwan S - Middle East Afr J Ophthalmol (2010)

Bottom Line: Ahmed valve implants are currently used to manage high-risk complicated adults and pediatric glaucoma when standard filtration surgery is unsuccessful.Despite its success, the Ahmed valve shunt has significant complications particularly in the anterior segment.Periodic observation of tube position is recommended.

ABSTRACT
Ahmed valve implants are currently used to manage high-risk complicated adults and pediatric glaucoma when standard filtration surgery is unsuccessful. Despite its success, the Ahmed valve shunt has significant complications particularly in the anterior segment. We report an unusual case of transcorneal tube erosion of an Ahmed valve implant in an adult that resulted from long-standing tube-corneal touch. Periodic observation of tube position is recommended.

No MeSH data available.

Mentions: The patient underwent diode cyclophotocoagulation to control his IOP. At the last follow-up visit, the area of repair appeared well healed; the conjunctiva was intact with a persistent corneal scar [Figure 2].Figure 2
