Idiopathic retinal vasculitis, aneurysms, and neuroretinitis
The present case appears in the Indian Journal of Ophthalmology.

A 21-year-old male with decreased vision (4/60 both eyes) for 3 months presented with idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) as seen by disc edema, vascular sheathing, and exudates in macula and around the disc, with aneurysmal dilatations on optic nerve head and retinal arterioles at or near their bifurcations on ultra-widefield fluorescein angiography.

Laboratory workup was normal. Three months following oral prednisolone, both eyes' macular edema decreased with two-line visual improvement. Although an isolated retinal vascular disease, IRVAN can cause severe visual loss due to neovascular sequelae.
