A Case Report on IRVAN Syndrome

Idiopathic retinal vasculitis, arteriolar macroaneurysms, and neuroretinitis (IRVAN) is a rare condition predominantly affecting young, healthy females without systemic disease. We present the case of a 35-year-old female who presented with a 3-month history of decreased visual acuity without associated symptoms. Ophthalmological examination revealed reduced visual acuity in both eyes, papillary oedema, stellate macular oedema, and haemorrhages bilaterally. Retinal imaging confirmed IRVAN syndrome. Treatment included pan-retinal photocoagulation (PRP) and intravitreal bevacizumab injections, resulting in macular oedema regression.
