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.
非动脉炎性前部缺血性视神经病变（NAION）是成人继青光眼之后导致永久性视神经相关视力丧失的第二大常见病因。NAION由导致视神经乳头灌注不足的复杂机制引起，并且常与2型糖尿病（DM2）和高血压等心血管危险因素相关。当小梁网被周边虹膜阻塞，导致眼压急剧升高时，就会发生急性闭角型青光眼（AAC）发作，这可能引发视神经乳头灌注减少。我们报告一例同时发生双侧AAC和NAION且合并DM2控制不佳的病例。
