The cause of idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) as to whether it is a congenital or acquired disorder is unresolved. We present a case of IRVAN in a patient with previously normal results of a retinal examination.
A woman in her early 30s presented with a 6-month history of bilateral blurred vision. She stated that she had experienced no illnesses associated with visual changes.
