    • “According to the International Retinoblastoma Staging System (IRSS), patients with extraocular RB had extraocular extension on pathologic examination (extrascleral/cut end of optic nerve involvement) after enucleation (Stage II) or demonstrated clinically evident extraocular extension on MRI at presentation (Stage III) [3].”

  3. 3.

    Page 4, 1st column, 3rd paragraph: The first sentence [Of the total 11 eyes which received IVC, 2 eyes had group B, 1 eye had group C, 4 eyes had group D, and 4 eyes had group E RB]. should be replaced by the following 2 sentences:

    Page 6, 1st column, 3rd paragraph: The first 2 sentences [In total, 12 of 29 (41.4%) cases with extraocular RB were found to have metastasis to various sites: CNS (8 cases, 27.6%), bone (2 cases, 6.9%), bone marrow and CNS (1 case, 3.4%), and lymph nodes and CNS (1 case, 3.4%). Metastasis developed in 2 cases with only extrascleral extension but no optic nerve involvement.] should be replaced with the following 3 sentences:

    • “In total, 12 of 29 (41.4%) cases with extraocular RB were found to have metastasis to various sites and grouped as IRSS Group IVa (2 cases)/IVb (10 cases) while the rest 17 (58.6%) were classified as Group II/III disease [3]. The metastatic sites were as follows: CNS (8 cases, 27.6%), CNS and bone marrow (1 case, 3.4%), CNS and lymph nodes (1 case, 3.4%), and bone (2 cases, 6.9%).
