Oral-ocular trans infection of Epstein Barr virus. A possible new way of transmission by wearing masks in the SARS-CoV-2 era

PURPOSE: To describe a case of an infective vitreitis with an exudative retinal detachment in a 56-year-old lady who was previously affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). OBSERVATIONS: A broad workup for infections including the main viruses and bacteria was performed. Salivary droplets, tear film and vitreous samples were collected, resulting positive only for Epstein-Barr virus (EBV). Viraemia and immunoglobulin M for EBV negative, whereas immunoglobulin G positive. The patient showed a simultaneous painless erosion on the right margin of the tongue that's with the lab swab demonstrated the presence of EBV at the same time the vitreitis in the left eye was present. CONCLUSIONS AND IMPORTANCE: Our speculation is that a continuous use of the mask, especially in immunocompromised subjects, it might create a new route for spreading infectious oral agents in the ocular area, and this case is a warning for all the ophthalmologists that have to be aware of this threatening possibility in the COVID era.
