Abstract
We therefore investigated the anti-Toxocara canis antibody profile in the aqueous humor in an animal model of ocular toxocariasis. We intravitreally injected T. canis larvae into the right eye of 4 rabbits; 2 rabbits were orally administered T. canis eggs. We collected serum, aqueous humor, and tear...

Abstract
Corneal larvae can be safely and successfully destroyed by Nd:YAG photodestruction. T. canis may be one of several nematodes responsible for DUSN. A careful examination of the anterior segment is essential in the management of patients with DUSN....

Abstract
We could identify the worm by optical coherence tomography as an area of hiper-reflectivity. The worms were laser photocoagulated and post-treatment optical coherence tomography scanning revealed improvement of edema, nerve fiber layer thinning and a retinal hyper-reflectivity where laser had been a...

Abstract
A case of ocular dirofilariasis in a female patient is presented. The zoonosis caused by parasites of the genus Dirofilaria is relatively rare in humans, with a higher incidence in south and central Europe, Asia and Africa. In Europe, dirofilariasis is mostly caused by the species Dirofilaria repens...

Abstract
Although human toxocariasis ranks among the most common zoonotic infections worldwide, it remains relatively unknown to the public. The causal agents are the nematode parasites Toxocara canis and T. cati, whose definitive hosts are dogs and cats, respectively. When embryonated eggs are accidentally...

Abstract
Impaired perfusion occurs in the retinal microvasculature of most children with CM. This is evidence for hypoxia and ischemia as important components in the pathogenesis of CM. Vessel occlusion and filling defects are likely to be due to sequestration of infected erythrocytes. Interventions which im...

Abstract
Tick infestation of ocular tissues is not common. Tick inoculation of the skin can locally lead to granuloma and abscess formation. More concerning, however, is the potential systemic sequelae that can result from transmission of zoonoses such as Lyme disease, Rocky Mountain spotted fever, Ehrlichia...

Abstract
We hypothesize that these localized lesions may be associated with topical immunomodulating therapy for KCS. Toxoplasmosis should be considered as a differential for canine conjunctivitis and corneal disease and has the potential to manifest in one or both eyes....

Abstract
We have shown that the eye involvement with Toxocara canis larvae is a phenomenon mainly produced once larvae have reached the brain. There is a direct relationship between the parasitic load and the number of ocular larvae. Moreover, the arrival of larvae to the eye is an independent event, unrelat...

Abstract
Our results indicate that ocular toxocariasis is mainly a pediatric disease. Serological screening is not informative for the diagnosis of intraocular Toxocara infection. Toxocara GWC analysis, however, can be of value when diagnosing patients with posterior focal lesions or vitritis of unknown etio...
