[Clinic use of Laser Doppler Flowmetry (LDF) in the study of subfoveal choroidal circulation]

Today our knowledge of the choroidal circulation is limited: we know its anatomy, but, on the other hand, its physiopathology remains to be fully. The choroid is involved in a number of important ocular diseases. The Laser Doppler Flowmetry (LDF) is a technique that allows non-invasive measurement of haemodynamic parameters of the subfoveal choroidal circulation. It is easy to use in daily clinic activity. The aim of this mini-review is to describe LDF studies of the choroidal circulation performed in healthy subjects under different environmental conditions, in subjects with ocular diseases, as well as studies of the effects of various drugs can induce on this circulation.
