Primary vascular occlusion in IRVAN (idiopathic retinal vasculitis, aneurysms, neuroretinitis) syndrome.
IRVAN is a rare retinal vascular disease characterized by the presence of aneurysmal dilations along the retinal arteriolar tree. Visual loss occurs from sequelae to proliferative changes or due to severe macular exudation and rarely from secondary vascular occlusion following laser photocoagulation of the aneurysms. We herein report a patient with a primary vascular occlusion in a patient with IRVAN and suggest that such patients may already have a natural predisposition to develop a vascular occlusion.
