Diffuse Unilateral Subacute Neuroretinitis Caused by Ancylostoma Hookworm

چکیده
Diffuse unilateral subacute neuroretinitis is an ocular infectious disease caused by several distinct nematodes. Definite identification of the involved nematodes is rarely achieved. We report on the molecular-based genetic identification of an Ancylostoma ceylanicum hookworm implicated in a case of diffuse unilateral subacute neuroretinitis in a child.

Ocular parasitic diseases: a review on toxocariasis and diffuse unilateral subacute neuroretinitis.
Parasitic infections may damage various ocular tissues, thereby causing visual dysfunction. In 1950, Wilder described the first case in which larval forms of nematodal intestinal roundworms (Ascaridoidea: Ascaris, Toxocara, Ancylostoma, Necator, and Strongyloides) were implicated as a cause of intraocular disease. This review focuses on two disorders associated with parasitic infections: ocular...

Diffuse unilateral subacute neuroretinitis (DUSN) is a form of uveitis that can potentially lead to blindness. In Brazil and other parts of South America, diffuse unilateral subacute neuroretinitis is an important cause of posterior uveitis in children and healthy young adults. If diagnosed and treated in early stage, allows a resolution of symptoms with improvement of visual acuity. If the dis...

متن کاملIdentifying live nematodes in diffuse unilateral subacute neuroretinitis by using the scanning laser ophthalmoscope.
OBJECTIVE To describe use of the scanning laser ophthalmoscope (SLO) to identify live nematodes in patients with diffuse unilateral subacute neuroretinitis. METHODS Infrared, red, and blue illumination (780, 633, and 488 nm, respectively) in an SLO were used to image and evaluate functional retinal status in patients with late-stage diffuse unilateral subacute neuroretinitis. An examination t...
