ICG Angiography

We use ICG Angiography to evaluate both the retinal and choroidal vasculature. This test is exquisitely useful to look at the choroid and allows us to determine if there was previous tissue damage which we see as staining. Choroidal vessels come from optic nerve circulation. We can also check for optic nerve damage.

ICG Angiography also allows us to look at leakage from the optic nerve to tell whether or not someone has raised intracranial pressure or inflammation. ICG Angiography is also highly useful when there has been hemorrhaging which can occur in cases of papilledema or in vitreous hemorrhages from diabetic changes as the dye allows us to see through to the underlying vasculature.
