摘要：
Purpose. - To evaluate the contribution of MRI exploration for the evaluation of orbital prothesis biocolonization. Patients and methods. - We studied ten eyes of ten children who underwent enucleation for retinoblastoma and synthetic hydroxyapatite orbital implantation. Each patient was examined by MRI imaging with gadolinium within 2 months to 1 year. Results. - After gadolinium administration, five implants showed an enhancement. Nodular enhancement around the implant was noted in one patient with a recurrence of retinoblastoma, and brain metastases were shown in two cases. None of the orbital implants was rejected. Conclusion. - Fibrovascular colonization reduces the risk of orbital implant migration. Magnetic resonance imaging is safe and effective in detecting extrusion or tolerance of the orbital implant.
