A case of presumed ocular toxocariasis in a 28-year old woman.

This is a case of presumed ocular toxocariasis in a 28-year old woman complaining of a sudden onset of nasal side field defect of the right eye. The patient had been suffering from uveitis for ten months. Fundoscopic examination of the right eye showed a rhegmatogenous retinal detachment. Furthermore, a retinochoroidal granulomatous lesion was observed nearby the tear site. Scleral buckling, cryotherapy, and gas injection(SF6, pure gas, 0.7 cc) were conducted. Mebendazole was prescribed for one month at 25 mg/kg per body weight daily. Even though the interventions resulted in the recovery of the field defect, anti-Toxocara IgG and IgE titer levels did not decrease when checked three months after the treatment ended. This is the first confirmed serological ocular toxocariasis case in Korea. Uveitis may be a clinical presentation prior to retinal detachment of a person with toxocariasis.
