Background: Blepharoconjunctivitis poses a diagnostic challenge due to its diverse etiology, including viral infections. Blepharoconjunctivits can be acute or chronic, self-limiting, or needing medical therapy.
Aim: To review possible viral agents crucial for accurate differential diagnosis in cases of blepharoconjunctivitis.
Methods: The PubMed database was searched for records relating to viral blepharoconjunctivitis. The search string generated was "("virally"[All Fields] OR "virals"[All Fields] OR "virology"[MeSH Terms] OR "virology"[All Fields] OR "viral"[All Fields]) AND "Blepharoconjunctivitis"[All Fields]".
Results: A total of 24 publications were generated from the search string. Reference lists from each relevant article were also searched for more information and included in this review. Viral etiologies such as adenovirus, herpes simplex virus (HSV), varicella-zoster virus (VZV), and Epstein-Barr virus (EBV) are frequently implicated. Adenoviral infections manifest with follicular conjunctivitis and preauricular lymphadenopathy, often presenting as epidemic keratoconjunctivitis. HSV and VZV infections can result in herpetic keratitis and may exhibit characteristic dendritic corneal ulcers. EBV, although less common, can cause unilateral or bilateral follicular conjunctivitis, particularly in immunocompromised individuals. Other potential viral agents, such as enteroviruses and molluscum contagiosum virus, should also be considered, especially in pediatric cases.
Conclusion: Prompt recognition of these viral etiologies is essential for appropriate management and prevention of complications. Thus, a thorough understanding of the clinical presentation, epidemiology, and diagnostic modalities is crucial for accurate identification and management of viral blepharoconjunctivitis.
