Macular microcirculation and macular oedema in branch retinal vein occlusion

The relationship between the blood-flow velocity in the perifoveal capillaries and macular oedema was investigated in patients with branch retinal vein occlusion (BRVO).This study compared 18 patients with BRVO and 16 healthy volunteers. Perifoveal capillary blood-flow velocity was measured on fluorescein angiograms with a scanning laser ophthalmoscope by the tracing method. Retinal thickness at the central fovea was measured by optical...
