Clinical Features and Treatment Outcomes of Vitreoretinal Lymphoma according to Its Association with CNS Lymphoma

Purpose: To compare the clinical features and treatment outcomes of different types of vitreoretinal lymphoma (VRL) that presents primarily, secondarily, or concurrently in association with CNS lymphoma.Methods: We retrospectively reviewed the medical records of 53 patients with VRL pathologically confirmed between 2000 and 2014 in two of the largest tertiary hospitals in Korea.Results: The proportions of primary, secondary, and concurrent VRL were 26%, 34%, and 40%, respectively. The primary VRL group had retinal infiltration most frequently (68%) among all groups and presented with the worst visual acuity at diagnosis (P=0.035). The diagnostic delay was significantly shorter in patients with secondary VRL (1.4months; P<0.001). Median overall survival was 31months in the entire cohort, and it was shortest in the concurrent VRL/CNS lymphoma group (18months; P=0.007).Conclusions: Ocular presentation and survival times may be different in VRL patients according to the association with CNS involvement.
