We report a case of delayed presentation of a child with retinoblastoma in his left eye because parents thought the change in iris colour in this eye was due to the innocent heterochromia irides that was previously diagnosed in his elder sibling. This late presentation necessitated enucleation of the affected eye followed by chemotherapy.
