title: Orbital cellulitis following implantation of aqueous drainage devices.
abstract: OBJECTIVE
  Orbital cellulitis (OC) as a complication of implanted aqueous drainage devices (ADD) for glaucoma is an uncommon phenomenon. The authors report two cases of infectious OC in patients with a history of congenital glaucoma and placement of ADD.
  
  
  METHODS
  Clinical records of two patients with ADD who subsequently developed OC were reviewed for presenting symptoms, signs, medical and surgical management, and final outcome.
  
  
  RESULTS
  In the first case, an 11-year-old girl was found to have evidence of OC 9 days after the implantation of a Krupin-Denver valve. In the second case, a 14-month-old girl presented with similar findings 8 months following the implantation of an Ahmed valve. In both cases, ultrasonography demonstrated evidence of orbital inflammation and in one patient computed tomography scan was consistent with OC. In both cases, prompt institution of systemic antibiotics resulted in resolution of the clinical signs. In the first case, diagnosis was made early and the patient was promptly treated with systemic antibiotics, resulting in resolution of her symptoms without the need for implant removal. Because of the delayed presentation in the second case, an infected implant had to be removed to achieve resolution in addition to aggressive with antibiotics treatment.
  
  
  CONCLUSIONS
  Although rare, infectious OC may occur following implantation of ADD. Early recognition and intervention may be required to achieve resolution of the infection.
