Area of Science:

  • Ophthalmology
  • Tropical Medicine
  • Parasitology

Background:

  • Ocular parasitic infections are uncommon, particularly in non-endemic regions.
  • Loa loa, a filarial nematode, is known to cause Calabar swellings and, rarely, migrate to the eye.

Observation:

  • A veterinary surgeon presented with intermittent visual disturbances and the sensation of a foreign body in her eye.
  • Surgical removal of an intact worm from beneath the conjunctiva confirmed the diagnosis of Loa loa ocular filariasis.

Findings:

  • Peripheral blood eosinophilia and positive filarial serology supported the diagnosis.
  • Microfilariae were not detected in peripheral blood smears.
  • The patient remained asymptomatic for 12 months post-treatment with diethylcarbamazine.

Implications:

  • This case highlights the importance of considering Loa loa in returned travelers presenting with ocular symptoms.
  • Prompt diagnosis and surgical removal, followed by antiparasitic treatment, lead to favorable outcomes.
  • Increased awareness is crucial for early detection and management of this rare but treatable condition.
