Survival of primary intraocular lymphoma (IOL) patients, including those with primary IOL alone or that simultaneously detected with primary central nervous system lymphoma (PCNSL). Patients with primary IOL that were subsequently diagnosed with PCNSL had a median progression-free survival (PFS) of 25.4 months (95% CI, 18.0-48.3 mo) and a 3-year overall survival (OS) rate of 90%.
