IMO has 3 different pieces of equipment

Images captured within 3 seconds

Duration: 3-5 minutes

What is an OCT-angio?

An OCT-angio is innovative new diagnostic equipment that uses optical coherence tomography (OCT) technology to obtain high-quality images of retinal circulation and provide a 3D view of the structures of the eye’s posterior pole.
This allows for an extremely precise examination of the eye’s vascular network at different depths, showing the mobility of blood flow in the vessels in specific layers of the retina and the choroid (the layer just below), as well as in the optic nerve head.

Of what does it consist?

Based on OCT (light emission) technology, this technique captures images within just 3 seconds. Unlike the conventional fluorescein angiography – a test traditionally used to study retinal circulation – it requires no intravenous injection of contrast dye to view the vascular section.
As a result, it is faster to perform and avoids discomfort and possible adverse effects for patients. This makes it a minimally invasive option that can be repeated more often for thorough control of diseases.

How is it performed?

The OCT-angio is performed in the consulting room in less than 10 seconds, without the need to prepare the patient beforehand or to dilate the pupil.

6 keys to the OCT-Angio

  • Painless test for patients.
  • Can be performed without prior preparation and without dilating the pupil.
  • Can be performed on patients of any age.
  • An appliance is used that emits a light into the eye through the pupil to analyze the different layers of the retina and the choroid.
  • It is a minimally invasive test for patients.
  • Test duration: 3-5 minutes.

In what cases is it used?

Included as state-of-the-art equipment in IMO consulting offices since late 2010, the OCT-angio is particularly relevant with regard to vascular diseases of the retina, as it allows for the study of abnormalities such as microaneurysms (dilation of blood capillaries) in diabetic retinopathy.
Another of its main indications is AMD, as it can detect the presence of neovessels (new abnormal blood vessels).
Because this is a new technique, however, the images obtained cover just the central part of the retina and, in the case of peripheral disorders, the conventional fluorescein angiography is still required.
It is also important to remember that, as well as being a powerful diagnostic tool, the OCT-angio is a great help in monitoring and evaluating the patient’s response to treatment. The usefulness and contribution of this innovative technology to glaucoma is also being considered.
