Among the 101 patients, 69.6 and 11.6 showed elevated immunoglobulin E levels and eosinophilia, respectively. We believe that OT may be associated with ingestion of uncooked meat, especially cow liver, in adult patients. Specifically, it has been observed that systemic toxocariasis, also called visceral larva migrans, tends to affect children younger than 3 years of age, possibly due to an increased rate of pica among this group, 3 whereas ocular toxocariasis typically presents in older children and young adults.
