Vitreoretinal large B- cell lymphoma (VR- LBCL): Clinical and pathological features and treatment outcomes.

Context: Vitreoretinal large B- cell lymphoma (VR- LBCL) is a type of non- Hodgkin lymphoma confined to the eye and central nervous system (CNS). The clinical manifestations of intraocular lymphoma can precede, occur simultaneously with, or follow disease at CNS sites. It differs from other forms of extra-nodal lymphoma; in that it does not involve systemic sites other than CNS.
