The African eye worm: a case report and review

Area of Science:

• Medical Parasitology
• Tropical Infectious Diseases
• Ophthalmology

Background:

• Loiasis is a parasitic filarial disease caused by the nematode Loa loa.
• It is endemic to West and Central Africa.
• Symptoms include episodic angioedema and subconjunctival migration of adult worms, earning it the name 'eye worm'.

Observation:

• A case report details a Cameroonian student presenting with loiasis symptoms at a US university clinic.
• This presentation is unusual given the rarity of loiasis in the United States.
• The patient's travel history and origin are key factors in the diagnosis.

Findings:

• The case confirms that Loa loa infections, though rare, can be encountered in the US.
• Diagnosis was based on clinical presentation and likely confirmed by parasite identification or serology (details not provided in abstract).
• This underscores the importance of considering endemic parasitic infections in travelers and immigrants.

Implications:

• Clinicians in non-endemic regions should be aware of loiasis in individuals from or who have traveled to endemic areas.
• Early recognition and diagnosis are crucial for appropriate management and preventing potential complications.
• This case highlights the need for continued vigilance regarding the importation of neglected tropical diseases.
