Purpose:
To describe a case of bilateral necrotizing retinitis induced by Angiostrongylus cantonensis.
Design:
Interventional case report.
Methods:
A 52-year-old Asian woman developed eosinophilic meningitis after eating several undercooked snails. One week later, sudden onset of vision loss was noted in both eyes. Widespread yellow retinal exudates were accompanied by bullous retinal detachment in both eyes.
Results:
Angiostrongylus cantonensis infection was confirmed by positive enzyme-linked immunosorbent assay of the serum and cerebrospinal fluid, and a positive Western blot test of the subretinal fluid. After treatment with mebendazole, levamisole, and corticosteroid, these necrotizing patches regressed gradually. However, the final visual acuity was no light perception.
Conclusions:
Angiostrongylus cantonensis infection should be considered as one of the causes of necrotizing retinitis.
