Ocular toxocariasis in adults

E R Raistrick, J C Hart

    The British Journal of Ophthalmology
    |May 1, 1976
    PubMed
    Summary
    This summary is machine-generated.

    Human toxocariasis, caused by toxocara larvae, affects adults, not just children. Antibody prevalence increases with age, and ocular toxocariasis symptoms in adults suggest this parasitic infection is more common in older populations.

    Area of Science:

    • Ophthalmology
    • Infectious Diseases
    • Parasitology

    Background:

    • Human toxocariasis is traditionally considered a pediatric disease.
    • Recent serological data indicate increasing Toxocara antibody prevalence with age.
    • Ocular manifestations are a significant concern in toxocariasis.

    Purpose of the Study:

    • To investigate the potential for ocular toxocariasis in adult patients.
    • To present evidence suggesting adult-onset toxocariasis.

    Main Methods:

    • Ophthalmoscopic examination of three adult patients with unilateral vision loss.
    • Serological testing using Toxocara fluorescent antibody tests.
    • Comparison of clinical findings with known pediatric ocular toxocariasis.

    Main Results:

    • Three adult cases presented with recent unilateral vision loss.
    • Ophthalmoscopic findings were consistent with toxocaral granulomata.
    • All three patients tested positive for Toxocara antibodies.

    Conclusions:

    • Adults can be affected by ocular toxocariasis.
    • Ocular toxocariasis should be considered in adults presenting with suggestive visual disturbances.
    • Serological evidence supports the diagnosis in affected adults.
