title: Optic neuritis secondary to Angiostrongylus cantonensis infection.
abstract: OBJECTIVE
  To describe a case of optic neuritis secondary to Angiostrongylus cantonensis infection.
  
  
  METHODS
  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).
  
  
  RESULTS
  After two weeks of larvicidal drugs and steroid treatment, the patient's visual acuity and color vision had dramatically improved.
  
  
  CONCLUSIONS
  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.
