Case Report: Ocular Toxocariasis: A Report of Three Cases from the Mississippi Delta

Abstract

Ocular toxocariasis can be vision threatening, and is commonly reported from tropical or subtropical regions. Knowledge of clinical manifestations from the United States, particularly in underserved areas such as the American South, is lacking. We report three cases of ocular toxocariasis in individuals from the Mississippi Delta, a rural community with prevalent poverty. Visual acuity was severely affected in two of the three cases. Increased awareness of ocular toxocariasis, which may have under-recognized frequency, will contribute to prompt diagnosis and treatment, which will ultimately improve patient health in the region.

Who Let the Dogs Out? Unmasking the Neglected: A Semi-Systematic Review on the Enduring Impact of Toxocariasis, a Prevalent Zoonotic Infection

“…The diagnosis of OT represents a diagnostic challenge, something that may explain the limited existing data regarding the therapy of OT [246]. Even though some published cases of OT showed a favorable outcome when anthelmintic drugs were combined with corticosteroids; the role of such drugs, for example, ABZ, remains unclear [246,[264][265][266][267]. However, the therapy of OT is based on anthelmintic drugs in combination with corticosteroids or surgical interventions, depending on previous ocular comorbidities and grade of inflammation [268][269][270].…”

Determinación de parásitos intestinales en perros con dueño de la ciudad de Talca, Chile, y su asociación con variables epidemiológicas

“…Además, la infección en perros adultos, especialmente en aquellos con hábitos outdoor, se puede originar a partir del consumo de hospederos paraténicos, tales como roedores o lagomorfos, ya que las larvas, una vez ingeridas, pueden originar gusanos adultos en el intestino sin sufrir una migración somática (Parsons, 1987). En el presente estudio, los perros con dueño con hábitos outdoor tienen un mayor riesgo de infección por T. canis y también podrían desempeñar un papel zoonótico en la toxocariasis humana (Inagaki et al, 2019;Gakosso et al, 2020;Nicoletti, 2020).…”

“…Interestingly, of the 11 cases who underwent serological screening 10 were seropositive for Toxocara IgG. 5 cases underwent ELISA testing of intraocular samples, all of which were positive for Toxocara IgG, including the one case with negative serology [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] .…”
