This case highlights an unusual ocular presentation of Toxocara infection in an asymptomatic individual. Diagnostic tests confirmed a subclinical infection, leading to a scarred worm lesion in the eye.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Parasitology

Background:

  • Ocular toxocariasis is a parasitic infection caused by the nematode Toxocara.
  • It typically presents with visual disturbances, but subclinical or asymptomatic cases are less common.

Observation:

  • A 52-year-old male presented with an incidental finding of a lesion in his right fundus.
  • The lesion was suggestive of a scarred Toxocara worm.
  • The patient had no prior ocular or systemic health issues and was asymptomatic.

Findings:

  • Blood count and chemistry were normal.
  • Serological tests were negative for Toxoplasma and Echinococcus.
  • Positive serology for Toxocara at a 1:4 dilution indicated infection.

Implications:

  • This case demonstrates a rare, subclinical presentation of ocular toxocariasis.
  • It underscores the importance of considering Toxocara even in asymptomatic patients with fundic lesions.
  • Further research into subclinical ocular toxocariasis may be warranted.
