Live intraocular Angiostrongylus cantonensis infection in Vietnam: a case report

Year: 2026

Type: article

Abstract: Purpose To report a rare case of intraocular angiostrongyliasis caused by Angiostrongylus cantonensis in Vietnam and to highlight its clinical features and management. Observations A patient presented with a live, motile nematode initially observed in the vitreous cavity, which subsequently migrated into the anterior chamber. The parasite was successfully removed through surgical extraction from the anterior chamber. Morphological examination and molecular analysis confirmed the organism as Angiostrongylus cantonensis . Postoperative treatment with antihelminthic medication and corticosteroids resulted in a favorable visual recovery without recurrence of ocular inflammation. Conclusions and importance Intraocular involvement of Angiostrongylus cantonensis is a rare manifestation of human angiostrongyliasis. This case highlights that early diagnosis and timely surgical removal of the parasite are critical for achieving favorable visual outcomes and preventing serious ocular complications, particularly in endemic regions.
