Non-arteritic anterior ischemic optic neuropathy as the only manifestation of a malignant hypertensive crisis: Report of a case

Abstract

Non-arteritic anterior ischemic optic neuropathy (NAION) is after glaucoma the most common optic neuropathy in patients over 50 years. It is known that high blood pressure (HBP) is an important risk factor for the development of NAION. It is also known that malignant arterial hypertension (MAH) could be accompanied by optic disc edema. However, MAH has not classically been considered a cause of NAION. We report the case of a 32-year-old patient who presented irreversible visual loss with a pattern compatible with NAION as the only manifestation of a hypertensive crisis.
