Fluorescein Angiography

Retinal angiography at Challa Eye Care Centre

Retinal Angiography is a diagnostic technique that enables our doctor to visualize the blood vessels & tissues in the eye.

With the Fluorescein Angiography process, our retina specialists observe the tissue more closely and can identify several eye diseases & keep track of changes over time.

What we do during Retinal angiography diagnosis

This diagnostic procedure will take less than 30 minutes at our centre.

  1. Initially, our ophthalmologists put drops in your eyes to dilate the pupil.
  2. After dilating eye, a colored dye (yellow), known as fluorescein is injected in a vein, in your arm.
  3. It takes around 10 - 15 seconds for a dye to travel till eye from the vein of your arm.
  4. The inserted dye spots the blood vessels & allows our eye doctors to look at retina & choroid
  5. When the dye passes via retina and choroid, our ophthalmic technician clicks a series of preliminary images using a special camera, known as the fundus camera.
  6. These images become a roadmap that aid our retina specialist to see where to focus treatment if a disease is identified.
  7. In the clicked images, macular hole & active wet macular degeneration areas are highlighted by the fluorescein dye.

What Happens After Retinal Angiography

After Retinal Angiography, your vision will be affected by the bright light of camera. This resolves in few minutes but your vision will remain blurry for many hours due to the eye drops which are used for dilating pupils.

Moreover, eyes will remain very sensitive to light. Thus, it is suggested to wear sunglasses after test that makes you feel more comfortable.

Retinal Angiography Risks & Side Effects

Your skin may become yellow, because the yellow dye travels to all veins of the body. However, after few hours, your skin pigmentation becomes normal.

Further, your urine may look orange or bright yellow for a maximum of 24 hours after angiography because the kidneys will filter the dye out of the blood.

Moreover, there would be a burning sensation on skin if dye leaks while injecting. This sensation would be just for few minutes.

Additionally, if an individual is allergic to the fluorescein dye, he or she may get hives or itchy skin and very rarely, they may experience breathing or other severe problems. Kindly, let us know if you have had any previous reactions with yellow dye used during angiography.

Prior to performing this test, our doctors will do a thorough analysis of your medical conditions and try to ensure that there are no side effects. They treat allergic reactions if they do occur with medications.
