What is ocular angiography?

Fluorescein fundus angiography uses fluorescein sodium as the contrast agent, which is quickly injected from the forearm vein. When the fluorescein sodium enters the fundus blood vessels with the blood flow, it continuously takes pictures of the fundus extravascular dye circulation and receives excitation. The fluorescent form emitted by the light can be used to observe the dynamic reincarnation process of the retina.

This examination method is mainly used for various macular diseases, various retinal, choroidal, and optic nerve diseases, and retinopathy caused by various systemic diseases, such as diabetic retinopathy, hypertensive retinopathy, Arteriosclerotic retinopathy, etc.
