Fundus fluorescein angiography

  1. 1. FundusFluorescein Angiography<br />Dr. AnandSudhalkar<br />Baroda<br />
  2. 2. Purpose<br />Highlight retinal and choroidal circulation<br />Detect early vascular pathologies<br />Confirm diagnosis<br />
  3. 3. How does it work?<br />Charateristics<br />applications<br />Absorbs 465-490nm, emits 520-530nm<br />Binding to plasma proteins, espAlbumin<br />Selective visualization of its passage<br />Confined to natural blood retinal barrier<br />
  4. 4. The sequence:<br />passage of dye after inj.<br />Visualization<br />10 to 15 sec : Short posterior ciliary arteries.<br />Choroidal flush, optic nerve head, cilioretinal artery.<br />11-18 sec: Retinal circulatiion, arteries-capillaries-veins. <br />20-25 sec: juxtrafoveal and perifoveal capillaries Maximal fluorescence around FAZ. The best time for PEAK PHASE IMAGING.<br />30 sec: First passage completed. Recirculation starts<br />After 10min: total disappearance of dye.<br />
  5. 5. The Interpretation<br />Hypo-fluorescence<br />Hyper-fluorescence<br />Blocked: Media opacity, Hem<br />Vascular Filling Defects: Occlusions, capillary non perfusion<br />Autofluorescence<br />Transmitted fluorescence<br />Hyperfluorescence: <br /> 1. Abnormal Vessels: Angiomas, Tumours<br /> 2. Leakage: NV, Plebitis<br /> 3. Pooling: CSR, PED <br /> 4. Staining: Disc, drusen, chorioret. scar <br />
  6. 6. Hypofluorescence<br />Vascular filling defects<br />Obstructions<br />
  7. 7. Transmitted fluorescence<br />
  8. 8. Blocked Fluorescence<br />
  9. 9. Hyperfluorescence<br />Vascular Leakage<br />Pooling<br />Staining<br />
  10. 10. FFA reveals NV<br />
  11. 11. FOCAL LEAKAGE<br />
