The diagnostic significance of immuno-diffusion test in atypical ocular toxocariasis

Abstract

A case of atypical intra-ocular Toxocara infestation in a 53 year-old Japanese male is described. Characteristic long, linear, subretinal tracts resembling a coiled circle were observed at the posterior pole and in the equatorial region of the fundus. These subretinal coiled tracks may be caused by larval appearance and migration in the subretinal apace of the fundus. Immuno-diffusion tests which may aid the diagnosis of ocular Toxocariasis and the implications of infestation are discussed.
