Abstract

Nowaday, zoonoses are an important cause of human parasitic diseases worldwide and a major threat to the socio-economic development, mainly in developing countries. Importantly, zoonotic helminths that affect human eyes (HIE) may cause blindness with severe socio-economic consequences to human communities. These infections include nematodes, cestodes and trematodes, which may be transmitted by vectors (dirofilariasis, onchocerciasis, thelaziasis), food consumption (sparganosis, trichinellosis) and those acquired indirectly from the environment (ascariasis, echinococcosis, fascioliasis). Adult and/or larval stages of HIE may localize into human ocular tissues externally (i.e., lachrymal glands, eyelids, conjunctival sacs) or into the ocular globe (i.e., intravitreous retina, anterior and or posterior chamber) causing symptoms due to the parasitic localization in the eyes or to the immune reaction they elicit in the host. Unfortunately, data on HIE are scant and mostly limited to case reports from different countries. The biology and epidemiology of the most frequently reported HIE are discussed as well as clinical description of the diseases, diagnostic considerations and video clips on their presentation and surgical treatment.

  • Canine dirofilarioses by Dirofilaria immitis and Dirofilaria repens are key examples of the success of vector-borne helminths spreading into non-endemic areas.

    “Although canine dirofilarioses by Dirofilaria immitis and Dirofilaria repens are key examples of the success of VBH spreading into non-endemic areas, another example is represented by Thelazia callipaeda eyeworm, an emergent pathogen of dogs, cats and humans in several regions of Europe.”

  • Ctenocephalides felis, Ctenocephalides canis and Pulex irritans are intermediate hosts for the filarial nematode Acanthocheilonema reconditum, which is transmitted via their bites to dogs and human beings and causes subcutaneous infection in animals and ocular disease in humans.

    “Ctenocephalides felis, C. canis and P. irritans are intermediate hosts for the filarial nematode Acanthocheilonema reconditum, transmitted via their bites to dogs and human beings and a cause of subcutaneous infection in animals and ocular disease in humans [46-48].”
  • Global climate change is influencing the ecology of helminths with multiple hosts and different transmission routes.

    “Indeed, global climate change is influencing the ecology of helminths with multiple hosts and different transmission routes.”
  • Feline and canine extra-intestinal parasitic nematodes are emerging in several countries and spreading into regions previously free from these parasites.

    “In the past few years the attention of the Scientific Community has been attracted by feline and canine extra-intestinal parasitic nematodes, which are emerging in several countries and spreading into regions previously free from these parasites.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
