The vital dye patent blue V is used as a negative contrast dye in order to obtain information about the vascular filling events of the choroid in relation to the retinal circulation and the papilla employing intravenous injection and serial photography. Patent blue is bound to plasma proteins to a limited degree and the angiograms therefore do not only picture the choroidal vessels but also reveal the filling of the choriocapillaris and the transcapillary exchange. It is demonstrated by microdensitometry that the patent blue leakage and subsequent reabsorption is rapid, and that the choroidal dilution curve almost parallels that of the retinal vessels. Our measurements might indicate a diffusion of patent blue from the choroid to the papillary tissue.
活性染料专利蓝V用作阴性对比染料，通过静脉注射和连续摄影获取有关脉络膜血管充盈情况与视网膜循环及视乳头之间关系的信息。专利蓝与血浆蛋白的结合程度有限，因此血管造影片不仅能显示脉络膜血管，还能揭示脉络膜毛细血管的充盈及跨毛细血管交换情况。显微密度测定法表明，专利蓝的渗漏及随后的重吸收很快，脉络膜稀释曲线几乎与视网膜血管的曲线平行。我们的测量结果可能表明专利蓝从脉络膜扩散至视乳头组织。
