Malignant Hypertension Leading to Non Arteritis Anterior Ischaemic Optic Neuropathy-Unilateral Involvement an Exigency

Abstract

Non arteritis Anterior Ischaemic Optic Neuropathy (NAION) is mentioned as loss of blood supply to the optic nerve further causing sudden onset and painless vision loss in eye. Exact mechanism, leading to reduced or loss of flow of blood to an optic nerve in NAION, is unknown but there are certain risk factors responsible for NAION like diabetes, malignant hypertension, Hypercholesterolaemia, platelet polymorphism, phosphodiesterase inhibitors, hyperhomocysteinemia, nocturnal hypotension, sleep apnoea, contribute to it. This case report is about a 40-year-old male patient who presented with a complaint of sudden onset vision loss in one eye which was further diagnosed as NAION on fundus examination. This shows association of malignant hypertension and NAION. Early diagnosis of the condition led to complete recovery of vision loss. Early management of blood pressure and timely management of NAION using antihypertensives and steroids in this patient found to be fruitful and patient regained his vision back.
