Eleven patients had unilateral involvement and one patient had bilateral optic neuropathy. Eight patients （66.7%） had a possible infection source to Toxocara. Six patients （50%） had painless acute optic neuropathy. Ten eyes had asymmetric, sectorial optic disc edema with peripapillary infiltration and three eyes had diffuse optic disc edema. Eosinophilia was noted in five patients （41.7%） and optic nerve enhancement was observed in eight of eleven eyes （72.7%） with available orbit magnetic resonance imaging （MRI）. Mean visual acuity significantly improved following treatment [mean logarithmic of the minimum angle of resolution （IogMAR） 0.94±0.56 at baseline and 0.47±0.59 at the final （P=0.02）]. Asymmetric optic disc edema with a peripapillary lesion and a history of raw meat ingestion were important clues for diagnosing Toxocara optic neuropathy. Additionally, Toxocara IgG enzymelinked immunosorbent assay （ELISA） test and evaluating eosinophil may be helpful for diagnosis.展开更多

We presented a case of progressive blurring of vision in a single eye of a 9-year-old boy.The presence of anti-toxocara antibody in serum samples helps to confirmation the diagnosis in our patient.Despite of treatment,the boy had lost his vision on the affected eye.展开更多
