“…[4] Some authors feel that if the nematode is located in the posterior pole of the retina, surgical removal should be selected over photocoagulation since laser can cause permanent scarring and visual loss. [56]…”

Diffuse unilateral subacute neuroretinitis (DUSN) is a subacute outer retinal inflammation due to the presence of a subretinal worm. The worm is identifiable in only 30% of the cases. The identification of the worm and laser photocoagulation of the worm remains the mainstay of treatment. Here, we describe a case of DUSN with a subretinal worm in the macula which was captured on Optical coherence tomography (OCT) scans and treated with laser photoooagulation.

“…Liver biopsy is performed in patients with VLM. Motile larva can be directly observed below the retina in the ocular form (64). Therefore, immunology methods determining the presence of specific IgG antibodies against the parasite's antigens are the main instruments in the diagnosis of toxocariasis.…”

Toxocariasis is a helminthic zoonosis caused by the presence and migration of animal nematode larvae in human tissue – mostly Toxocara canis and Toxocara cati. The term visceral larva migrans syndrome was used for the first time in 1952 by Beaver et al. who described the typical clinical presentation. There are difficulties in the diagnosis of toxocariasis because of the variety of symptoms depending on the larva localisation in different tissues and organs. Currently, the most commonly used serological methods are ELISA and Western blot. The disease is characterised by diverse clinical picture and thus toxocariasis is very rarely identified and most patients remain undiagnosed, which requires in-depth study of this widespread but still problematic zoonosis.

“…A definitive laboratory diagnosis of human toxocaral infection uses the histopathological examination of tissue specimens including liver [29], lung, brain [26,27] and enucleated eye tissue [30]. A mobile larva or larval tract can be directly observed in the retina in patients with OT [31], and larvae were found in CSF [32]. Since histopathological examinations are mostly not feasible, the laboratory diagnosis of human toxocariasis relies upon serology.…”

For the last four decades, knowledge about human toxocariasis with regard to its epidemiology, pathophysiology, clinical spectrum, and imaging or laboratory diagnosis has substantially progressed. Knowledge about specific therapy with anthelmintics has lagged behind. To date, only four drugs are registered for human use, and their efficacy has rarely been assessed in prospective controlled trials. It is likely that the repurposing of potent anthelmintics from veterinary medicine will improve this situation. Due to its wide availability and a lack of major side effects during short regimens, albendazole has become the drug of choice. However, its efficacy should be more precisely assessed. The role of anthelmintics in the treatment of neurological or ocular toxocariasis remains to be clarified. Prophylactic measures in humans or companion animals are efficient and represent first-line treatments for the control of this zoonosis. Unfortunately, their implementation in areas or countries where toxocariasis epidemiology is driven by poverty is quite difficult or unrealistic.

Extraktionsversuch einer intraretinalen Nematode im papillomakulären Bündel

Abstract: We demonstrated that nematode larvae can be removed successfully from the central retina using vitrectomy techniques. By that means the damage to the visual functions can be limited. Near the posterior pole surgical extraction of the worm may be favorable compared to photocoagulation.
