Overview

Retinoblastoma may be classified into several subtypes based on the International Retinoblastoma Staging System (IRSS).

Stage III A overt orbital disease
Stage III B preauricular or cervical lymph node extension
Stage IV Metastatic disease
Stage IV A
  • haematogeneous metastasis without CNS involvement
  • single lesion
  • multiple lesions
Stage IV B

CNS metastatic involvement prechiasmatic lesion CNS mass leptomeningeal disease
