When Fluorescein sodium is injected for Fluorescein Angiography, approximately how many cc are used?

Fluorescein sodium, when used for fluorescein angiography, typically requires a dosage in the range of 5 cc. This dosage is optimal for achieving sufficient vascular visualization, allowing for clear imaging of the retinal and choroidal circulation.

In the context of fluorescein angiography, the injection is generally performed intravenously, and the volume used is significant enough to ensure that the dye circulates effectively and reaches the retinal vasculature. A volume of around 5 cc strikes a balance between visibility and the risk of potential side effects, as using too much fluid may not necessarily enhance the imaging quality but could increase the risk of adverse reactions, while too little might not provide adequate visualization.

Thus, the choice of 5 cc aligns with common clinical practice for this procedure, ensuring that the desired imaging characteristics are achieved without compromising patient safety.
