Eye salvage in diffuse anterior retinoblastoma using systemic chemotherapy with periocular and intravitreal topotecan.

Diffuse anterior retinoblastoma is an infrequent presentation in which the tumor is confined to the anterior segment, and there is no retinal mass. An 18-month-old Asian Indian boy presented with white spots in the left eye. There were extensive anterior segment seeds without a retinal tumor. Fine-needle aspiration biopsy confirmed the diagnosis of retinoblastoma, and the patient received intravenous chemotherapy with a combination of vincristine-carboplatin-etoposide, periocular topotecan, and intravitreal topotecan to achieve complete tumor regression.
