Vascular networks in retinal arterial macroaneurysms.
Retinal arterial macroaneurysms (MA) are a rare pathology, often associated with old age, arterial hypertension, artherosclerosis, and retinal vein occlusions. Here, we present two unusual cases of MA in patients with arterial hypertension, that displayed small vascular networks at the site of the MA on angiography. Resulting exudative changes and the networks themselves regressed after laser treatment, and visual acuity improved. Those vascular networks might represent collateral vessels forming as a rare sequel after spontaneous occlusion of the MA.
