The aim of this study was to retrospectively determine clinical features, treatment outcomes, and overall survival in four patients with metastatic retinoblastoma at presentation. The mean age at diagnosis was 63 months (range: 24-108 months). Three patients had overt orbital disease of at least one eye and one patient had microscopic orbital disease with scleral infiltration on histopathology.
