Ophthalmology·2000

A young girl experienced vision loss and optic disc swelling, likely due to Toxocara optic neuropathy. Prompt treatment with oral prednisone successfully resolved the condition, highlighting the importance of timely diagnosis and intervention for this rare condition.

Area of Science:

Ophthalmology
Infectious Diseases
Parasitology

Background:

Toxocara species are common roundworm parasites that can cause visceral larva migrans.
Ocular involvement in toxocariasis can range from mild inflammation to severe vision loss.

Observation:

A 14-year-old female presented with acute vision loss in her right eye.
Examination revealed bilateral optic disc swelling, indicating increased intracranial pressure or direct optic nerve inflammation.

Findings:

Extensive diagnostic workup was performed to identify the cause of the optic neuropathy.
The clinical presentation and resolution following treatment strongly suggested a diagnosis of Toxocara optic neuropathy.

Implications:

This case underscores the importance of considering parasitic infections in the differential diagnosis of optic neuropathies, especially in pediatric patients.

Early recognition and treatment of Toxocara optic neuropathy can prevent permanent visual impairment.
