However, the similarity of the geographic distribution of chorioretinal disease on Truk and of filariasis as noted in a survey of Micronesia³ was proposed as evidence of a relationship between the two diseases.^1,2 Although chorioretinal lesions have been described in infections with Onchocerca, the filarial organism endemic in tropical America and Africa,^4-7 little is known about eye lesions caused by Wuchereria, the only type of filaria common in the South Pacific.^8,9

Because chorioretinitis has been repeatedly associated with infection by Toxoplasma,^10-14 a survey of 192 natives on Truk was . . . [Full Text PDF of this Article]
