Is fundus fluorescein angiography dangerous?

When I was in the ophthalmology department of our hospital, I saw many cases, but none of them had the described side effects. The most important thing is that patients with sound liver and kidney function can do it, and they must drink water desperately to expel contrast media after finishing. Personally, I think the biggest side effect is that people's whole skin turns yellow, and others really don't see greater danger.

Assuming that patients with poor cardiovascular system and liver and kidney function do it, there may be great problems, at least the rescue is more difficult, because the degradation of contrast agent is extremely weak and depends entirely on liver and kidney function.

I hope my answer can help the landlord.
