Diffuse Unilateral Subacute Neuroretinitis Caused by Ancylostoma Hookworm

Emerg Infect Dis. 2017 Feb;23(2):343-344. doi: 10.3201/eid2302.142064.


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.
