Summary
This summary is machine-generated.

Dirofilariasis, a rare parasitic infection in humans, can cause eyelid swelling and preseptal cellulitis. Diagnosis requires considering this zoonotic disease, especially in regions like southern India.

Area of Science:

  • Ophthalmology
  • Parasitology
  • Infectious Diseases

Background:

  • Preseptal cellulitis and eyelid swelling are common ophthalmic presentations.
  • Dirofilariasis is a zoonotic parasitic infection typically affecting animals.

Observation:

  • Three patients presented with unilateral eyelid swelling mimicking preseptal cellulitis.
  • Clinical examination revealed a mobile, firm eyelid mass.
  • CT scans showed non-specific inflammation, and antibiotic treatment provided only temporary relief.

Findings:

  • Excision biopsy confirmed parasitic infestation by Dirofilaria in all three cases.
  • Histopathological and microbiological examinations identified the causative agent.

Implications:

  • Dirofilariasis should be considered in the differential diagnosis of migratory subcutaneous swellings and conjunctival nodules.
  • This zoonotic infection, though rare in humans, warrants consideration in ocular presentations, particularly in endemic areas like southern India.
