What is Angiography?
It is a technique for examining the circulation of the retina and choroid on the back of the eye.
Why it is important?
It helps to diagnose of diabetes, eye tumors, night blindness and retinal disorders.
Why it is done?
- To display the eye veins
- To investigate the presence of any mass within the eye
- To determine vascular leakage in the eye
- To investigate bleeding of blood vessels in the eye
- To determine a vascular congestion in the eye
- To examine the eye inflammation
- To determine the location for the laser treatment on the retina
- To confirm the effectiveness of the treatment
- To detect the age-related yellow spot disorders
How it is done?
Angiography is a technique for examining the blood vessels in the eye with using a special dye. It helps to see some unseen problems, to diagnose and choose the treatment for the patient. In the beginning, the patient’s pupils are enlarged with eye drops and an injection is made. After the medicine is reached to the eye within the circular system, the blood vessels can be seen more clearly. At this moment, by using a special microscope and a blue light, an angiogram is obtained by photographing the medicine. With this photograph, the patient is diagnosed. This usually takes 30 minutes and there is no harm to the patient’s eyes.
Optical Coherence Tomography (OCT)
The OCT is also known as a new generation of technology in unmedicated imaging.
The movement of the moving red blood cells within the vessels are captured with OCT-B screening, and rendered as an image.
In OCT imaging angiography, vascular and structural information is displayed on a single screen without invasive intervention. As in traditional eye angiography, patient is not given medicine intravenously. 3D angiographic imaging of the eye is provided with this technique.
Retina and choroid layers can be examined separately for ease of visual assessment.
It is a non-invasive, drug-free angiography.
With only one scan, OCT angiography is provided.
With 3D , the rear layers of the eye can be evaluated one by one.
It is a drug-free angiography.
With one scan, the procedure is complete in a short period of time.
The pupils are not enlarged with eye drops.
To take an image in one scan lasts only 8-10 seconds.
