A 68-year-old woman experienced an infection of a porous polyethylene orbital implant caused by Capnocytophaga after a dental procedure. The infection was unresponsive to both topical and oral antibiotics and required removal of the porous polyethylene orbital implant. Capnocytophaga is a capnophilic, gram-negative bacillus. Capnocytophaga is a normal commensal of the mouth and is responsible for both gingivitis and periodontal disease. Capnocytophaga is a rare cause of ocular infections. This is the first reported patient with an infection of a porous polyethylene orbital implant caused by Capnocytophaga. The authors believe infected integrated orbital implants must be removed because neither topical or systemic therapy provide effective treatment.
