摘要: The purpose of the present study was to effect a single instillation latanoprost on human optic nerve head (ONH) and retinal circulation. Using laser-speckle tissue blood flow analysis, normalized blur (NB; quantitative index velocity) measured every 0.125 sec at temporal ONH site free visible surface vessels. Measurements were averaged for 3 cardiac cycles (NBONH). Color Doppler Imaging (CDI) also used evaluate peak systolic velocity (PSV), endo-diastolic (EDV), resistive (RI) in central artery (CRA) mean (MV) vein (CRV). One drop 0.005% instilled into one eye its vehicle other eleven healthy volunteers double-blinded manner. bilateral NBONH, CDI parameters, intraocular pressure (IOP), (BP), pulse rate (PR) performed before, 45, 90, 180, 270 min after instillation. After instill...
