Optical Coherence Tomography Angiography (OCTA) is a precise digital microangiography of the eye. It allows to study the anatomy of blood vessels of the retina and choroid.
OCTA enables doctors to detect the earliest signs of pathologies in the structures of the eye.
Latest developments in optical technology make it possible for modern OCT tomographs equipped with special angiography software to examine the previously inaccessible structure of the eye – the choroid. Located between the retina and the sclera, consisting entirely of a network of blood vessels, until recently it was very difficult to access by any diagnostic techniques.
OCTA is an ideal tool for an early diagnosis and for treatment efficacy evaluation in diseases such as:
- age-related macular degeneration (AMD),
- diabetic retinopathy (DR),
- central retinal vein occlusion (CRVO),
- central retinal artery occlusion (CRAO).
Optical Coherence Tomography Angiography (OCTA) is performed with an OCT scanner equipped with the appropriate software. The principle of the examination is identical to that of OCT. The difference lies in the area of examination.
OCTA is a non-invasive examination. It takes a few minutes and requires no special preparation. It does not require intravenous contrast. It is safe for pregnant women and children.
Pupil dilation is not always required; the decision is made during the appointment.
Attention! Patients who had their pupils dilated should not drive for about 3 hours after instillation of the drops.
