title: Complications following ex-press glaucoma shunt implantation.
abstract: OBJECTIVE
  To report post-operative course and complications in patients who underwent Ex-Press glaucoma shunt placement.
  
  
  METHODS
  Small case series.
  
  
  METHODS
  Four patients were referred for management following Ex-Press shunt implantation. Patients underwent complete ophthalmologic evaluation and were appropriately managed.
  
  
  RESULTS
  Of the four patients, two had inadequate control of intraocular pressure related to bleb failure caused by subconjunctival scar tissue formation. One patient experienced suprachoroidal hemorrhage 5 days after shunt placement followed a year later with conjunctival erosion and shunt rim exposure. Endophthalmitis from conjunctival erosion over the Ex-Press shunt rim was observed in one patient.
  
  
  CONCLUSIONS
  Patients with subconjunctival implantation of the Ex-Press shunt should be monitored closely for possible conjunctival erosion that can lead to endophthalmitis and failure from fibrosis.
