Ocular disease associated with Epstein-Barr virus infection

Area of Science:

• Ophthalmology
• Virology
• Immunology

Background:

• Epstein-Barr virus (EBV) is a ubiquitous herpesvirus, infecting approximately 90% of adults and causing infectious mononucleosis.
• Recent research suggests a growing association between EBV infection and a range of ocular conditions.
• These include conjunctivitis, keratitis, uveitis, retinitis, and ophthalmoplegia.

Purpose of the Study:

• To review the current understanding of Epstein-Barr virus (EBV) involvement in ocular diseases.
• To highlight the diagnostic challenges and uncertainties in establishing EBV as the causative agent in ophthalmic conditions.

Main Methods:

• Literature review of studies reporting EBV and ocular disease.
• Analysis of diagnostic methods for EBV infection, including serologic tests.
• Examination of clinical evidence linking EBV to specific eye conditions.

Main Results:

• EBV is implicated in numerous ocular diseases such as keratitis, uveitis, and retinitis.
• While EBV-specific serologic tests can confirm infection, they do not always confirm causality in ocular manifestations.
• The pathogenesis of EBV-related ocular diseases remains uncertain due to diagnostic limitations.

Conclusions:

• Despite a high prevalence of EBV and reported associations with ocular disease, definitive causal links are often questionable.
• Diagnostic challenges, including lack of culture confirmation and animal models, hinder clear understanding.
• Further research is needed to elucidate the precise role of EBV in various ophthalmic conditions.
