idiopathic retinal vasculitis, aneurysms, and retinitis: a case report

purpose: to report a case of idiopathic retinal vasculitis, aneurysm, and retinitis [irvan] with angiographic and optical coherence tomography (oct) findings. case report: a 15-year-old girl with a 2 -month history of decreased visual acuity in both eyes and best corrected visual acuity of 20/70 in both eyes was referred to the retina clinic. mild inflammation was present in anterior chamber and vitreous cavity. there was severe exudative maculopathy, optic disc swelling, multiple tied knot-like aneurysmal dilations of retinal arterioles, and retinal vasculitis bilaterally. systemic and laboratory work-up were negative. oct illustrated severe retinal edema, cystic spaces in nerve fiber layer (nfl), and excrescences on the retinal surface around posterior pole. conclusion: in this report, we present oct findings in a case of irvan syndrome about which few reports are available. the findings show that reduced axonal conduction and schisis-like cavities in nfl may be present.
