Retinoblastoma is a significant cause of childhood eye cancer world-wide with prognosis dependent upon early diagnosis and treatment but also upon accurate classification of tumours. Unilateral incidence is normally non-hereditary compared with bilateral incidence. Survivorship is much better for unilateral compared with bilateral and trilateral retinoblastoma but the early signs are important to detect and photography can assist in identifying no return of “red-eye” during flash photography or a distinctive white or yellow appearance of the tumour.
