摘要: Abstract PURPOSE: To determine capillary blood flow measurements in eyes with branch retinal vein occlusion using a scanning laser Doppler flowmeter. METHODS: Retinal areas and corresponding ipsilateral nonbranch areas, 11 equivalent of the contralateral fellow eye 12 consecutive untreated patients, 16 age-matched normal control subjects were measured flowmetry. A template consisting eight squares, each field 100 × μm (10 10 pixel) space interval 500 equidistant horizontally vertically was used to obtain all subjects. Mean volume, flow, velocity obtained by averaging mean values field. We avoided measurement over large vessels prevent aliasing artifact cells from moving faster than sampling frequency. RESULTS: Branch have significantly decreased microvascular volume (P = .0009), .02), .016) compared same eye. also .001), .0042), .0044) .0012), .008), .02) areas. CONCLUSION: Average are lower healthy retinas. The ability noninvasively measure hemodynamic changes bed may be relevant development new therapies for retinovascular disease.
