Abstract

Retinal laser-Doppler velocimetry (LDV) is a powerful non-invasive technique for measuring retinal and optic nerve blood flow¹. To date, the laser delivery and detection systems necessary for LDV in the eye have been incorporated in a slit-lamp microscope^2,3 and fundus camera⁴. These instruments are optimized for a seated subject with eyes facing forward, but are not well suited to other configurations. To provide for LDV under more general circumstances (such as during a surgical procedure on an operating table), a LDV system has been incorporated in an operating microscope (model OPMI-1, Zeiss). This instrument and its applications are described below.
