Retinal arterial macroaneurysm in a patient with congenital heart disease.

In 1973, Robertson' introduced the term macroaneurysm to describe large aneurysms arising on a main retinal arteriole within the first three orders of bifurcation. Retinal arteriolar macroaneurysms occur primarily in elderly people with hypertensive and generalised arteriosclerotic vascular disease. 1-8 The condition may be the result of aging, hypertension, and arteriosclerosis.' Local damage to the vessel wall by emboli may also lead to retinal arteriolar macroaneurysms.3 We report here a case of retinal arterial macroaneurysm in a 20-year-old patient with congenital heart disease associated with embolic retinal disease.
