Abstract: The Epstein-Barr virus (EBV) belongs to the family of herpesviruses, subfamily Gammaherpesvirinae, and genus Lymphocryptovirus. Despite this classification, there are two serotypes of the Epstein-Barr virus, namely type A and type B. Both types play significant roles in the development of viremia. Additionally, EBV infection can lead to lymphadenopathy, upper respiratory tract obstruction, spleen rupture, thrombocytopenia, and recently, there has been increased emphasis on the connection between this virus and certain malignant neoplasms. Diagnosing this virus can be challenging if clinicians rely solely on serological confirmation. In some cases, it is necessary to perform more specific methods, in addition to considering the clinical picture and history, to prove the presence of the virus in blood, nasopharyngeal swabs, and other tissue samples. The aim of this paper is to present the severity and consequences caused by the Epstein-Barr virus and to emphasize the importance of preventive measures in preventing the virus from coming into contact with susceptible individuals. Prevention plays a crucial role in reducing contact with the virus. Since the infection spreads via droplets, wearing masks in healthcare facilities and regular hand washing are hygiene priorities to prevent infection and further transmission.

The Epstein-Barr Virus (EBV), a member of the Herpesvirus family, occurs commonly and infects more than 90% of people worldwide. Most of systemic EBV infections throughout childhood and adulthood are typically asymptomatic or paucisymptomatic. Even though ocular involvements in EBV infections are infrequently reported, an increasing number of ocular manifestations have been previously reported . Ocular manifestation caused by EBV infection involved all segments of the eye, including oculoglandular syndrome, dry eye syndrome, dacryoadenitis, conjunctivitis, episcleritis, keratitis, uveitis, choroiditis, retinitis, retinal vasculitis, and papillitis. Previous reports found neurologic complications such as papilledema, optic neuritis, ophthalmoplegia, impaired accommodation, and facial nerve palsy. Any atypical ocular inflammatory process should be considered EBV infection in the differential diagnosis. The ocular manifestations of systemic EBV infection are varied and have not been emphasized. And the role of EBV infection in ocular manifestations should be fully described.
