OCT - angiography

• Ophthalmologic examination may require pupil dilation - Patient sees worse for about 2-3 hours after the examination.
  During this time, he should not drive or perform activities that require correct vision.
• Zapping the drops may cause watery eyes - for the patient's safety and comfort, it is recommended to wash off eye makeup before counseling.

OCT is optical coherence tomography of the fundus of the eye is a modern test that allows evaluation of the organ of vision. The examination is mainly used in the diagnosis of retinal diseases. It is a non-invasive examination and thus can replace more complicated methods. Performing an OCT examination of the eye makes it possible to obtain a cross-sectional model of the tissues. The whole procedure is somewhat similar to ultrasound. A beam of light is introduced into the organ, which, by reflecting, informs about the position of the various parts. OCT examination is performed in people who, for example, have age-related macular degeneration. Diabetes is also an indication. People who have macular edema present are also referred for OCT of the eye. These may be of unknown origin. This is when OCT helps make the diagnosis.

Angio OCT (OCTA) is an OCT examination of the macula with imaging of the retinal and choroidal vessels using spectral tomography. Imaging of the vessels is done at different depths of the retina and choroid so that it is possible to localize lesions and determine their nature. OCTA does not require the administration of contrast and is a completely non-invasive procedure.

Course of the examination: To visualize the relevant area on the fundus, the patient is asked to direct his or her gaze in different directions. Periodically, the patient may be asked to refrain from blinking. It may be necessary to dilate the pupils with drops - this is decided by the doctor. The examination is painless, the light beam with which the camera takes measurements is completely safe for the eye.
