[Interest in the Heidelberg Retinal Flowmeter for measuring the retinal and papillary blood flow].

The Heidelberg Retina Flowmeter is a combination of Doppler flowmetry and laser scanning technology. It is new non-invasive method performing a high definition topography of perfused microvessels of the retina and optic nerve head with simultaneous evaluation of blood flow. Recent studies prove significant decrease of optic nerve head blood flow and juxtapapillary blood flow in primary open angle glaucoma.
