    Pars plana vitrectomy offers significant benefits for chronic ocular toxocariasis, particularly when inflammation is unresponsive to steroids or causes vision-threatening structural changes. This surgical intervention can improve vision and prevent further complications.

    Area of Science:

    • Ophthalmology
    • Parasitology

    Background:

    • Chronic ocular toxocariasis presents a significant challenge in ophthalmology.
    • Intraocular inflammation in toxocariasis often requires intensive management.

    Observation:

    • Subtotal pars plana vitrectomy was performed in four patients with chronic toxocaral endophthalmitis.
    • Two patients with inflammation unresponsive to corticosteroids showed dramatic improvement post-vitrectomy.
    • One patient had a retrolenticular membrane removed, preventing amblyopia.

    Findings:

    • Vitrectomy relieved macular vitreoretinal traction in two patients.
    • A peripheral traction retinal detachment was cured in one patient.
    • The study suggests new guidelines for laboratory confirmation of ocular toxocariasis.

    Implications:

    • Pars plana vitrectomy is a valuable treatment for chronic ocular toxocariasis when medical management fails.
    • Vitrectomy can prevent or reverse vision loss caused by structural changes like tractional retinal detachment and membranes.
    • This approach may improve outcomes for patients with severe or complicated toxocaral endophthalmitis.
