PurposeEnucleation is a common treatment modality performed for pediatric retinoblastoma patients, and the resultant defects are reconstructed using an ocular prosthesis. The prostheses are modified or replaced periodically, as the child develops due to orbital growth and patient‐error. The purpose of this report is to evaluate the replacement frequency of prostheses in the pediatric oncologic population.MethodsA retrospective review was completed by the two senior research investigators, of patients that had ocular prostheses fabricated following enucleation of their retinoblastoma from 2005 to 2019 (n = 90). Data collected from the medical records of the patient included the pathology, date of surgery, date of prosthesis delivery, and the replacement schedule of the ocular prosthesis.ResultsDuring the 15‐year study period, 78 enucleated observations (ocular prosthesis fabricated) were included for analysis. The median age of the patients at the time of delivery of their first ocular prosthesis was calculated to be 2.6 years (range 0.3–18 years). The median time to the first modification of the prosthesis was calculated to be 6 months. The time to modification of the ocular prosthesis was further stratified by age.ConclusionPediatric patients require modification of their ocular prostheses throughout their growth and development period. Ocular prostheses are reliable prostheses with predictable outcomes. This data is helpful to set an expectation among the patient, parent, and provider.
