Introduction
Fluorescein angiography can be used to examine retinal vascular diseases such as retinal periphlebitis, macular edema, and retinal vein occlusion. It not only aids in diagnosing these conditions but also helps in formulating appropriate treatment plans. The procedure usually takes a short time, approximately half an hour, and results are typically available about one hour after the examination.
Fluorescein angiography usually refers to fundus angiography, which generally takes about half an hour.
Fundus angiography is a relatively routine examination method in ophthalmology. During the procedure, contrast dye is injected into the antecubital vein, and then special filters along with a fundus camera are used to capture images of the retinal blood vessels and their perfusion status. This technique helps diagnose various retinal vascular diseases, such as retinal periphlebitis, retinal neovascular diseases, macular edema, and retinal vein occlusion. It not only aids in disease diagnosis but also assists in formulating appropriate treatment plans. The examination itself is typically brief, lasting approximately 30 minutes, and results are usually available within about an hour after completion.
Patients with known allergic constitutions should inform their doctor prior to undergoing angiography to prevent possible allergic reactions. Additionally, individuals with severe liver dysfunction should not undergo fundus angiography.
