Detailed Mapping of Retinal Blood Flow and Vascular Disease
**Fundus Fluorescein Angiography (FFA)** is a specialized diagnostic test that provides a dynamic, detailed view of the blood circulation in the **retina** and underlying **choroid**. This test is vital for diagnosing conditions involving damaged or abnormal blood vessels.
During an FFA, a fluorescent dye (**Fluorescein**) is injected into an arm vein. As the dye travels through the eye's blood vessels, a high-speed camera captures a rapid sequence of images. This process highlights areas of leakage, blockages, abnormal blood vessel growth (**Neovascularization**), and poor circulation, which are crucial for treating conditions like **Diabetic Retinopathy** and **Wet Age-related Macular Degeneration (AMD)**.

Consult our retina specialist to determine if FFA is right for you.
Diabetic Retinopathy
Identifies areas of capillary closure (non-perfusion) and leakage in the macula that require urgent treatment.
Wet AMD & CNV
Crucial for locating and mapping the extent of Choroidal Neovascularization (CNV) for targeted anti-VEGF injections.
Vascular Blockages
Diagnoses and assesses the damage caused by Retinal Vein or Artery Occlusions (RVO/RAO).
Guides Treatment
Provides the high-precision roadmap necessary for laser photocoagulation and targeted drug delivery.
