To describe the clinical outcomes of patients receiving a quasi-integrated porous polyethylene orbital implant following enucleation for retinoblastoma.
A retrospective review of all retinoblastoma patients who received the quasi-integrated porous polyethylene implant following enucleation during the 56-month period between October 2000 and May 2005 was conducted.
Ten patients were identified who received the quasi-integrated porous polyethylene implant as a buried, primary orbital implant. Approximately 6 weeks following implantation, a custom-fitted prosthesis was made by an impression technique to provide a "lock-and-key" fit with the orbital implant in the majority of patients. Follow-up ranged from 2 months to 78.5 months following surgery, with an average of 36 months. One case of implant exposure was noted, with no other significant complications. Good motility of the prosthesis was noted in all cases.
The quasi-integrated porous polyethylene orbital implant is safe to implant and provides good prosthetic motility without the need for pegs or screws. It was associated with an exposure rate similar to other commonly used implants following enucleation in retinoblastoma cases.
