To identify demographic and clinical factors associated with delayed diagnosis in patients with primary vitreoretinal lymphoma (VRL).
Retrospective, tertiary referral center-based cohort study of all patients at Mayo Clinic in Rochester, Minnesota, with a biopsy-proven diagnosis of VRL from January 1, 2000, to October 31, 2022.
There were 87 patients included during the 22-year study period with 73 patients (83.9%) diagnosed with VRL upon initial evaluation at the tertiary center, with the other 14 patients (16.1%) diagnosed later. The median referral time was 4.8 months (range: 0-113 months). Patients who received an initial diagnosis of inflammatory uveitis or another incorrect diagnosis elsewhere were referred slower than those initially diagnosed with VRL (P = 0.04). The most common incorrect initial diagnosis from an outside institution was inflammatory uveitis (n = 35, 40.2%). When patients were split into four groups based on referral time, prior use of corticosteroids was associated with a significant delay in referral (P = 0.03).
Diagnosing VRL continues to be challenging, as months-long delays from initial evaluation to expert referral center evaluation are common. Prior use of corticosteroids was associated with delay in diagnosis and referral time, underscoring the need to increase awareness regarding differences between VRL and uveitis.
