A 68-year-old man presents to the general practitioner (GP) with visual complaints in the right eye. He intermittently loses vision in the right eye, which he describes as a curtain vertically across his visual field. Each episode lasts about two or three minutes. He denies eye pain, eye discharge or headaches.
His past medical history is significant for poorly controlled type 2 diabetes mellitus, hypertension and hypercholesterolaemia.
On examination, his pupils are of normal size and reactive to light. There is no scalp tenderness. Blood test results are pending, and his electrocardiogram (ECG) shows normal sinus rhythm, without ischaemic changes.
A provisional diagnosis of amaurosis fugax (AG) is being considered.
