[Myxoma of the left atrium: a cause of retinal artery embolism not to be ignored. Apropos of a case]. / Myxome de l'oreillette gauche: une cause d'embolie artérielle rétinienne à ne pas méconnaître. A propos d'une observation.

We report a case of retinal artery obstruction in a 56-year-old woman which proved to be a first symptom of a left atrial myxoma. The patient also had an inflammatory syndrome and a transient embolism of the cerebellum and the left leg. Two dimensional echocardiography showed an atrial mass compatible with myxoma. This diagnosis was confirmed by histological analysis of the surgically-removed tumour.
