Anterior ischemic optic neuropathy is the most common cause of acute optic neuropathy in older age groups and very rare below 50 years of age. The causes can be non-arteritic (NAION) or arteritic (AION), the latter being associated with giant cell arteritis (GCA or Temporal arteritis). In the majority of cases it is idiopathic, but known risk factors are hypertension (HTN), diabetes (DM), Obstructive Sleep apnea (OSA) and drugs. Visual loss secondary to NAION as a presenting feature of renal artery stenosis is rarely seen. Herein we describe a young male patient who presented with progressive loss of vision in his left eye which was acute in onset. He improved over few weeks with a vision of 20/20(right eye) and 20/80(left eye) and was discharged home.
