This population-based study was undertaken to obtain information on age-, sex-, and race-specific incidence of nonarteritic and arteritic anterior ischemic optic neuropathy for the State of Missouri and for Los Angeles County, California. Among subjects who were 50 or older the estimated mean annual incidence rates per 100,000 population were 2.30 for nonarteritic anterior ischemic optic neuropathy and 0.36 for arteritic anterior ischemic optic neuropathy. White individuals appear to be at significantly higher risk of developing nonarteritic anterior ischemic optic neuropathy than black or Hispanic individuals, suggesting possible genetic predisposition.
这项基于人群的研究旨在获取密苏里州和加利福尼亚州洛杉矶县非动脉性和动脉性前部缺血性视神经病变按年龄、性别和种族划分的发病率信息。在50岁及以上的受试者中，每10万人的非动脉性前部缺血性视神经病变估计年发病率为2.30，动脉性前部缺血性视神经病变为0.36。白人个体患非动脉性前部缺血性视神经病变的风险似乎显著高于黑人或西班牙裔个体，这表明可能存在遗传易感性。
