扫描激光眼底镜微视野检查是一种非损伤性的视功能检查 ,包括局部视网膜功能检查和注视点检查。该技术使用激光扫描眼底镜 ,在直视眼底的条件下 ,定量、定位地测量中心 2 0°～ 4 0°范围局部视网膜功能 ,测量注视点及评价其稳定性。该项检查可对研究黄斑部疾病的发展过程和评价治疗效果提供有价值的信息。注视点的检查 ,有助于评价局部视野检查的可信度 ,同时为医疗人员在行黄斑手术和激光时避免医源性的注视点损伤提供帮助 Scanning laser ophthalmoscopy Microvisual examination is a non-invasive visual function test, including local retinal function and fixation points. The technology uses laser scanning ophthalmoscope to measure quantitatively and locally the local retinal function in the range of 20 ° ~ 40 ° in the direct view of the fundus, measure the fixation point and evaluate its stability. This examination can provide valuable information for studying the development of macular diseases and evaluating the efficacy of treatment. The fixation of the fixation point helps to assess the reliability of the local visual field examination and at the same time helps the medical staff avoid iatrogenic fixation damage during macula and laser surgery
