Description

The International Classification for Intraocular Retinoblastoma (ICRB) is the newer retinoblastoma staging system, which takes into account what has been learned about the disease in recent decades. Due to early diagnosis, extraocular spread of retinoblastoma has become less common, however, for cases with extraocular involvement, the most commonly used staging system is the Reese-Ellsworth staging system.
The ICRB divides intraocular retinoblastomas into 5 groups, labeled A through E, based on the chances that the eye can be saved using current treatment options.
Group A - Small tumors (3 mm across or less) that are only in the retina and are not near important structures such as the optic disc (where the optic nerve enters the retina) or the foveola (the center of vision).
Group B - All other tumors (either larger than 3 mm or small but close to the optic disc or foveola) that are confined to the retina.
Group C - Well-defined tumors with small amounts of spread under the retina (subretinal seeding) or into the jelly-like material that fills the eye (vitreous seeding).
Group D - Large or poorly defined tumors with widespread vitreous or subretinal seeding. The retina may have become detached from the back of the eye.
Group E - The tumor is very large, extends near the front of the eye, is bleeding or causing glaucoma (high pressure inside the eye), or has other features that mean there is almost no chance the eye can be saved.
