Diffuse Unilateral Subacute Neuroretinitis (DUSN)

Diffuse Unilateral Subacute Neuroretinitis Caused byAncylostomaHookworm

“…In this case, we obtained a positive ELISA result for Toxocara canis , another helminth implicated in DUSN ( 3 ). Because the confirmatory immunoblot test was negative, we assume the ELISA result to most likely have been caused by unspecific cross-reactions.…”

“…Several nematodes can induce DUSN, in particular Ancylostoma spp. , Baylisascaris procyonis , and Toxocara canis ( 3 ), but the actual cause remains unknown. Because the nematodes are only rarely surgically extracted from the eye, a definite identification is hardly ever achieved ( 3 , 4 ).…”

“…, Baylisascaris procyonis , and Toxocara canis ( 3 ), but the actual cause remains unknown. Because the nematodes are only rarely surgically extracted from the eye, a definite identification is hardly ever achieved ( 3 , 4 ). Noninvasive laser therapy is the treatment of choice for DUSN because it leads to the death of the nematode, thereby stopping the inflammatory process ( 1 ).…”

“…The finding of a hookworm in DUSN seems plausible because Ancylostoma spp. nematodes have been repeatedly proposed as an etiologic agent in DUSN ( 1 , 3 , 4 ). …”

Role of PASCAL and optical coherence tomography angiograpgy in the treatment of diffuse unilateral subacute neuroretinitis caused by large live motile worm

“…The causative agent can be divided into a small and large worm. Several species of nematodes, including Toxocara canis,[3] Baylisascaris procyonis[4] and Ancylostoma caninum have been suggested as the potential causative agent. The treatment mainly consists of destruction of the visible worm or the yellow crops of lesion using laser photocoagulation in combination with oral anthelmintic therapy.…”
