Certain chalazia may stem from viral conjunctivitis. Caution is advised when using intralesional corticosteroids for these viral-induced chalazia cases.

Area of Science:

  • Ophthalmology
  • Virology
  • Pathology

Background:

  • Chalazia are typically associated with meibomian gland dysfunction or blepharitis.
  • The etiology of chalazia, particularly those presenting with conjunctivitis, remains incompletely understood.
  • Investigating potential infectious causes is crucial for effective management.

Observation:

  • A prospective study identified 27 patients with chalazia and diffuse follicular conjunctivitis without other known causes.
  • Patients presented with symptoms suggestive of viral infections, including recent systemic viral illness, contact with affected individuals, and preauricular lymphadenopathy.
  • Ocular findings included viral corneal disease in some cases.

Findings:

  • Evidence strongly suggests a viral etiology for a subset of chalazia.

  • Viral particles were identified via transmission electron microscopy in conjunctival biopsies from affected patients.
  • Systemic viral illness and contact with infected individuals were common in patients with viral-induced chalazia.

    • Implications:

    • Chalazia can be a manifestation of viral conjunctivitis, expanding the differential diagnosis.
    • Treatment strategies, particularly the use of intralesional corticosteroids, require careful consideration in suspected viral cases.
    • Further research into the specific viruses involved could lead to targeted therapies.
