Cognitive and Adaptive Functioning in Youth With Retinoblastoma: A Longitudinal Investigation Through 10 Years of Age.

The results generally indicate that previously demonstrated declines in functioning from diagnosis through age 5 improve by age 10. However, these early declines, as well as the continuous difficulties observed in patients treated with enucleation only, suggest the need for early intervention services for young patients with retinoblastoma. Continuous monitoring of the psychological functioning of patients with retinoblastoma, increased awareness of risk factors such as unilateral disease, enucleation, race, and surgery-only treatment plans, and referral to Early Intervention for all patients are indicated.
