Description
Summary:Non-arteritic anterior ischaemic optic neuropathy (NAION) is the second most common cause of permanent optic nerve-related visual loss in adults after glaucoma. NAION is caused by complex mechanisms that lead to optic nerve head hypoperfusion and is frequently associated with cardiovascular risk factors like type 2 diabetes mellitus (DM2) and hypertension. An attack of acute angle-closure (AAC) occurs when the trabecular meshwork is blocked with peripheral iris that causes an abrupt rise in intraocular pressure, which can trigger a decrease in optic nerve head perfusion. We present a case with simultaneous and bilateral AAC and NAION in association with uncontrolled DM2.
