激光扫描眼底镜同时荧光血管造影和吲哚青绿血管造影

眼底荧光血管造影 (ＦＦＡ)和吲哚青绿血管造影 (ＩＣＧＡ)是检查和记录视网膜、脉络膜血管状态的重要诊断技术。现代的眼底荧光血管造影在 6 0年代就应用于临床 ,人们已经有很清楚的认识 ;而吲哚青绿血管造影是 90年代中期才开始应用 ,虽然目前ＦＦＡ、ＩＣＧＡ的检查在各地已

Fluorescein Angiography and Indocyanine-Green Angiography using a confocal scanning laser ophthalmoscope-the Heidelberg Retina Angiogrophy

Fluorescein Angiography (FA) and Indocyanine-Green Angiography (ICGA) are well established diagnostic techniques for documenting the retinal and choroidal vasculature,respectively,in both normal and pathological conditions of the fundus. While standard fundus cameras use film for recording the images,digital systems use internal hard disks and optical disks(CDs) for the recording and storage of the acquired images. A scanning laser ophthalmoscope (SLO) uses digital imaging and acquisition, but differs greatly from the digital imaging systems which are added to fundus cameras in their illumination source and optical properties.Laser scanning systems,in particular confocal laser scanning systems,have important advantages as compared to conventional photographic systems,mainly in image resolution and contrast and in three-dimensional imaging. This article represents the angiographic imaging capabilities of an SLO-the HRA-in several entities,both in FA and ICGA.
