Purpose: To evaluate the efficacy of the different diagnostic tests for vitreoretinal lymphoma (VRL). Methods: A cohort of 150 patients with a presumed diagnosis of VRL. Vitrectomy samples were analysed for cytology, monoclonality [polymerase chain reaction (PCR)] and cytokine levels, and anterior chamber taps were analysed for cytokine levels. Vitreoretinal lymphoma (VRL) was diagnosed after confirming the clinical suspicion with vitreal or brain cytology. Results: Vitreoretinal lymphoma (VRL) was diagnosed in 78 patients. Vitreal cytology was positive for 53/132 patients (40.2%), 36/53 had positive cytology from both the eye and the brain. Additional 25 patients had positive brain cytology. Vitreal PCR for monoclonality was positive for 32/91 patients (35.2%). Vitreal cytokine levels of interleukin (IL)-10/IL-6 were >1 for 47/110 patients (43.1%). For cytology, PCR and cytokine analysis, the respective sensitivity was 73.6%, 46.0% and 81.4%, and the accuracy of the tests was 85.6%, 60.4% and 80.9%, respectively. All three tests were available for 79 patients. In this subset, for cytology, PCR and cytokine analysis the respective sensitivity was 79.5%, 41.0% and 82.1%, respectively, and the accuracy of the tests was 89.9%, 60.8% and 81.0%, respectively. Conclusion: Cytokines analysis has an important role in the diagnosis of VRL. We suggest analysing cytokines levels in all cases suspected of VRL along with cytology and PCR analysis.
