老年性黄斑变性(简称SMD)是50岁以上老年人低视力和盲目的主要原因之一。本病在我国日益受到重视,并从心理物理学和视觉电生理对SMD 视功能进行研究,为其早期诊断提供临床依据,及时预防治疗,推迟发病年限,防止老年人的盲目。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,可准确测试黄斑光阈值,已用于青光眼和SMD 的早期诊断。而光阈值的变异又与短期波动
Age-related macular degeneration (referred to as SMD) is one of the main causes of low vision and blindness in people over 50 years of age. The disease is increasingly valued in our country, and from the psychophysics and visual electrophysiology of SMD visual function research, to provide a clinical basis for its early diagnosis, timely prevention and treatment, postponed the onset of the disease, to prevent blindness in the elderly. With the advent of electronic computers, the Auto-Paremeter increases diagnostic ophthalmology. The Humphrey Visual Field Analyzer is a multi-static static quantitative visual field tester that accurately tests macular thresholds and has been used in the early diagnosis of glaucoma and SMD. The variation of light thresholds is also related to short-term fluctuations
