年龄相关性黄斑变性(简称AMD)是西方国家50岁以上老年人低视力和盲目的首要原因。视力突然丧失主要发生在渗出性AMD的新生血管阶段,故过去对这种病变进行激光治疗,但近年来研究已逐渐重视AMD早期非渗出性阶段,使其早期诊断,推迟发病年限,预防老年人的盲目。随着电子计算机的兴起,自动视野计提高了眼科诊断水平。Humphrey视野分析仪是一个多点静态定量的视野检查仪,供视中心30°内的视野检查,并准确地测试黄斑功能,近年来多用于青光眼的早期诊
Age-related macular degeneration (referred to as AMD) is the primary cause of low vision and blindness in the elderly over the age of 50 in Western countries. In recent years, the sudden loss of vision mainly occurs in the stage of neovascularization of exudative AMD, and laser treatment of this lesion was used in the past. However, in recent years, studies have gradually attached importance to the early non-exudative phase of AMD, making it early diagnosis, postponing the onset of disease, The blindness of the elderly. With the rise of electronic computers, automatic perimeter to improve the level of ophthalmic diagnosis. Humphrey visual field analyzer is a multi-static static quantitative visual field detector for visual field within 30 ° examination and accurate testing of macular function in recent years, more for early diagnosis of glaucoma
