ABSTRACT

Retinoblastoma is the most common primary intraocular malignant tumor of early childhood, and 95% of all cases are diagnosed before the age of 5 years. Tumors are evaluated and classified based on laterality, genetic features, the number, location and size of foci. Currently, systemic and intaarterial chemotherapy are the most commonly used management options worldwide. Group A tumors are treated with focal techniques including transpupillary thermotherapy, cryotherapy, or laser photocoagulation. Groups B and C tumors are managed with systemic chemotherapy and focal consolidation techniques. Group D lesions are best treated with systemic chemotherapy, subtenon carboplatin injection or external beam radiotherapy. Alternatively, groups B, C and D tumors can be primarily treated with intraarterial chemotherapy. Intravitreal melphalan injection can be an alternative treatment for eyes with recurrent or persistent vitreous seeding. Group E eyes are often enucleated, however, depending on the fellow eye, systemic or intraarterial chemotherapy may be administered. Systemic chemotherapy is also mandatory if high-risk histopathological features are found after enucleation.
