A Case of Orbital Abscess following Porous Orbital Implant Infection

Purpose: We present a case of orbital abscess following porous orbital implant infection in a 73-year-old woman with rheumatoid arthritis. Methods: Just one month after a seemingly uncomplicated enucleation and porous polyethylene (MedporⓇ) orbital implant surgery, implant exposure developed with profuse pus discharge. The patient was unresponsive to implant removal and MRI confirmed the presence of an orbital pus pocket. Despite extirpation of the four rectus muscles, inflammatory granulation debridement and abscess drainage, another new pus pocket developed. Results: After partial orbital exenteration, the wound finally healed well without any additional abscess formation. Conclusions: A patient who has risk factors for delayed wound healing must be examined thoroughly and extreme care such as exenteration must be taken if there is persistent infection.
