Optical coherence tomography angiography versus fluorescein or indocyanine green angiography: legal implications for ophthalmologists

Optical coherence tomography angiography (OCTA) is a non-invasive imaging technique able to show real-time volumetric data on chorioretinal vasculature. The most commonly used angiographic techniques in visualizing vascular changes are fluorescein (FA) or indocyanine green angiography (ICGA). Dye-based techniques require intravenous dye injection which can cause side effects. The physician has the responsibility to decide which diagnostic instrument is more appropriate. Legal implications are due to the side effects of dye injection. OCTA test can be performed without side effects.
