Summary
This case study details a rare instance of ocular larva migrans in an 8-year-old child caused by Toxocara canis. Treatment involving antihelminthics and steroids led to stabilized ocular lesions.
Area of Science:
- Ophthalmology
- Parasitology
- Pediatrics
Background:
- Ocular larva migrans (OLM) is a rare condition caused by parasitic infections, often Toxocara species.
- Toxocara canis infection in humans can lead to severe ocular manifestations, particularly in children.
Observation:
- An 8-year-old child presented with bilateral ocular lesions, including peripheral chorioretinal granuloma, papillitis, and vasculitis.
- Diagnostic findings included significant eosinophilia (37%), positive serology in blood and aqueous humor, and elevated vitreous humor immunoglobulin E levels.
Findings:
- Fluorescein angiography confirmed the presence of vascular and chorioretinal lesions.
- The diagnosis of ocular larva migrans due to Toxocara canis was established based on clinical presentation and laboratory results.
Implications:
- This case highlights the importance of considering parasitic infections in pediatric ophthalmology, even with rare presentations.
- Successful management involved a multi-modal approach including antihelminthic therapy, corticosteroids, and cryotherapy, leading to lesion stabilization.
