title: [Retinal Arterial Macroaneurysms (RAM)--pathology, differenzial diagnoses, and therapy].
abstract: Retinal arterial macroaneurysms (RAM) are unilateral, solitary, acquired saccular or fusiform dilatations of the large arterioles of the retina, usually within the first three orders of bifurcation. They are associated with systemic vascular conditions such as hypertension and arteriosclerotic disease and occur most commonly in elderly women. Cases of simple RAM are predominated by the vascular ectasia. These macroaneurysms regress without treatment and without causing decreased visual acuity and will usually remain undetected. Complex RAM often go along with vision loss due to haemorrhage or oedema affecting the macula. Poor visual outcome may occur secondary to foveal exudates and subfoveal haemorrhage, the latter appear as pre-retinal, intra-, and subretinal haemorrhage. This overview discusses conservative and surgical therapeutic options for complex cases.
