Retinoblastoma is the most common intraocular malignancy of childhood. In most cases, parents are the first to notice leukocoria and other symptoms before undergoing a prolonged period of stress before diagnosis. The purpose of this study was to determine prediagnostic intervals of patients with retinoblastoma at an oncology tertiary center (Instituto Nacional de Cancer) in Rio de Janeiro, Brazil, and relate them to stage at diagnosis, eye salvage, and survival.
