Insights
A rare case of congenital ocular toxocariasis caused early-onset strabismus in a five-week-old infant. This finding suggests congenital transmission of Toxocara, differing from typical acquired infections.
Area of Science:
- Ophthalmology
- Parasitology
- Pediatrics
Background:
- Strabismus is a common condition in infants, often with various underlying causes.
- Ocular toxocariasis is a parasitic infection of the eye, typically acquired postnatally.
- Congenital ocular toxocariasis is exceptionally rare, with limited documented cases.
Purpose:
To report a case of strabismus in a five-week-old infant, likely secondary to a rare occurrence of congenitally acquired ocular toxocariasis.
Methods:
Retrospective case report.
Results:
A five-week-old male infant with left exotropia was referred to pediatric ophthalmology and to a vitreoretinal specialist. Fundoscopic examination revealed a granuloma with associated retinal folds and tractional retinal detachment typical for ocular toxocariasis. Serology revealed positivity for Toxocara antibodies, consistent with the clinical diagnosis of ocular toxocariasis.
Conclusion:
Ocular toxocariasis is typically thought to be secondary to acquired Toxocara infection secondary to fecal-oral transmission. In this case of early-onset strabismus secondary to ocular toxocariasis, it is hypothesized that this is a presentation of congenitally acquired toxocariasis.
