“…Ocular alveolar hydatidosis caused by E. multilocularis may occur after spreading of the larval cestodes to other sites. For instance a choroidal eye mass has been reported in a patient with history of visceral alveolar hydatid disease with cerebral metastasis [115]. Human infection by E. oligarthrus is very rare with only a few cases published in the international literature, two of which involve the eye [116].…”

Zoonotic helminths affecting the human eye

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.Homines amplius oculis, quam auribus creduntSeneca Ep 6,5Men believe their eyes more than their ears

“…They acquire the infection by oral ingestion of eggs, which develop into metacestodes. The initially hepatic lesions may spread to other locations, especially in advanced cases (Williams et al, 1987;Kondo et al, 1996). The larvae form a cluster of multiple small vesiculated cysts, in which protoscoleces may develop.…”

Alveolar echinococcosis (AE) is a rare, but potentially severe zoonotic disease caused by Echinococcus (E.) multilocularis. Recent findings indicated an increasing importance of AE for non-human primates living in regions endemic for E. multilocularis. The death of five cynomolgus monkeys (Macaca fascicularis) and a lowland gorilla (Gorilla g. gorilla) due to AE raised concern about the incidence of this parasite in the Basle Zoo. Consequently, a project was initiated to investigate the prevalence amongst an affected group of cynomolgus monkeys, as well as in foxes and mice. Three out of 46 monkeys were seropositive for E. multilocularis antigen. In two of these monkeys and in another three animals, which were seronegative, structures compatible with metacestodal cysts were observed using ultrasonography. Seven out of 35 free roaming foxes caught at the zoo were positive for an intestinal E. multilocularis copro-antigen ELISA, four of them shed taeniid eggs simultaneously. No lesions compatible with AE were present in 50 necropsied mice from the zoo area. These results indicate that the fox population is a potential source to introduce E. multilocularis and may thus represent a risk for the zoo animals.

“…Ocular infection in general and subretinal infection in particular are exceedingly rare. Williams et al reported a choroidal hydatid cyst accompanied by multiorgan involvement in an Alaskan patient [7]. In South Africa, Konar and Pillay reported visual loss in a HIV-infected patient due to bilateral echinococcus cysts and tractional retinal detachment [8].…”
