Abstract
ABSTRACTPurpose: To investigate the association between multiple evanescent white dot syndrome (MEWDS) and Epstein-Barr (EB) virus infection.Methods: A prospective, consecutive case series study was performed in patients with the characteristic findings of MEWDS. Patients received EB viral-specific antibody serologic tests.Results: Five cases of MEWDS who had prodromal flu-like symptoms were enrolled, comprising 2 women and 3 men with a mean age of 34. Mean diopter of myopia was −7.5. During acute onset of MEWDS, EB virus infection was confirmed by positive EB virus serology test. One showed positive EB viral capsid antigen (EB-VCA) IgM, and the other four showed highly elevated titer of EB-VCA IgG more than 1:160. Two months later, paired serum virus serology data showed negative EB-VCA IgM, or prior EB-VCA IgG titer decreased four-fold in the recovery stage.Conclusion: MEWDS may be associated with acute systemic EB virus infection. Ocular symptoms might develop due to this infection or represent virus-induced autoimmune inflammatory retinitis.
