Text

Background: Primary vitreoretinal lymphoma (PVRL) is a rare, but high malignant intraocular tumor with limited prognosis. Clinical findings of PVRL may simulate uveitis. Difficulties to confirm diagnosis, even after cytological and immunhistochemical analyses of vitreal specimens, are often. MiRNAs in cerebrospinal fluid have been demonstrated as a reliable marker for primary CNS lymphoma. Objective of this analysis was to evalute preliminary miRNA data in a PVRL specimen.

Methods: A single vitreal specimen from a 53 year old female patient with confirmed PVRL (analysed by the Coupland laboratory/Liverpool) was analysed for miRNAs by Real-Time PCR and compared to controll specimens (7 normal and a single uveitis specimen).

Results: At least 16 fold upregulation of three marker miRNAs has been seen in the PVRL specimen in comparison to the control group of 8 specimens. These differences have also been seen between the PVRL and the uveitis specimen.

Discussion: MiRNAs have the potential to be a valuable diagnostic tool for PRVL and especially to differentiate between PVRL and uveitis. Further analysis with a larger number of patients are necessary to increase first evidence.
