Orbital retinoblastoma: Where do we go from here?

Abstract

Diagnosis of orbital retinoblastoma traditionally carries a dismal prognosis. Although its incidence is less in the developed countries, it continues to contribute to an epidemic of extraocular disease at diagnosis in the developing world. Orbital retinoblastoma encompasses a wide range of distinct clinical entities with varying tumor load. There are no standard treatment protocols as of now but the current preferred management is multimodal with a combination of initial high-dose chemotherapy, surgery, external beam radiotherapy and prolonged chemotherapy for 12 cycles. Though orbital retinoblastoma is a catastrophic event, rapid advances on many fronts, especially the genetic, makes the future appear brighter than what it is now. This review looks at all the new frontiers that are in store in the near as well as the distant future. Looking at the ever expanding horizons makes one believe of a definite hope that one day we will conquer this disease as we have conquered many others in the past.
