Abstrakt:	Introduction: Studies aimed at a direct research of human herpes viruses (HHVs) in the tumor material and eye media have not been carried out so far. Research goal to establish the frequency of detection HHVs DNA in the biomaterial of the eye and blood and to assess the specific humoral immunity to the causative agents of herpes virus infections in patients with uveal melanoma. Materials and Methods: 38 patients with the uveal tract tumor were examined for the presence of DNA of HHV types 1 and 2 (HSV-1, 2), Cytomegalovirus (CMV), Varicella Zoster virus (VZV), EpsteinBarr virus (EBV) and herpes viruses 6 and 8 types (HHV-6, HHV-8) in tumor tissue, vitreous body, aqueous humour and blood plasma by real-time polymerase chain reaction; blood serum was studied by enzyme-linked immunosorbent assay (ELISA) for IgG and IgM antibodies to HHVs. Results: EBV DNA was present in tumor tissue in 20.6% of cases, in vitreous body in 4.2%, in blood plasma in 2.7%, and was not found in aqueous humor. Ig G antibodies to HSV-1, 2 and CMV were detected in 97.3% of cases, VZV 94.6%, HHV-6 32.4%, antibodies to HHV-8 were not detected. 20 patients (55.6%) had reactivation of chronic HSV-1, 2 infection, and 14 (38.9%) patients had reactivation of CMV infection. Markers of chronic EBV infection were found in all patients, its atypical reactivation was observed in 2 cases (5.4%). Conclusion: Our findings suggest the possible participation of EBV in the oncogenesis of the uveal tract and emphasize the need for further in-depth study of this problem.
