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

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.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.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 (1.4 months; P 0.001). Median overall survival was 31 months in the entire cohort, and it was shortest in the concurrent VRL/CNS lymphoma group (18 months; P = 0.007).Ocular presentation and survival times may be different in VRL patients according to the association with CNS involvement.
