Optic Neuritis Secondary to Angiostrongylus cantonensis Infection

Abstract

Purpose: To describe a case of optic neuritis secondary to Angiostrongylus cantonensis infection. Method: Case report of a patient with eosinophilic meningitis secondary to A. cantonensis infection. The patient developed a sudden decrease in visual acuity with a visual field defect and color vision loss in his left eye. Both visual evoked potential and clinical manifestations suggested the diagnosis of optic neuritis (os). Result: After two weeks of larvicidal drugs and steroid treatment, the patient's visual acuity and color vision had dramatically improved. Conclusion: Optic neuritis may occur in patients with A. cantonensis meningitis. Treatment with a combination of steroid and larvicidal agents may be beneficial to these patients.
