OCT is optical coherence tomography of the eye. The OCT eye tomograph has a resolution 10 times greater than that of an ultrasound machine, so the result of the OCT examination can be compared with a histological image of the retina (that is, the examination has the same value as if the doctor were examining a tissue slice taken surgically). The test is non-contact, performed on an outpatient basis. It takes a few minutes, but a lot of experience on the part of the evaluating physician is required to properly assess the results.

What does the study look like? A beam of light is introduced into the eye, which, by reflecting, informs about the position of its various parts. The light beam with which the camera takes measurements is completely safe for the eye. For the patient, this means that the examination is painless and non-contact – he or she looks fixedly at the point indicated by the doctor, occasionally refraining only from blinking.

The tomograph makes it possible to obtain highly accurate, spatial cross-sections of the retina. The diagnostician can assess the structure of the retina, the thickness of its nerve fibers, the condition of the blood vessels and the condition of the optic nerve. OCT examination can be repeated many times without any health consequences for the patient.

Optical coherence tomography of the eye is one of the most important tests when diagnosing retinal diseases, in people who have age-related macular degeneration (ADM) or diabetic complications (diabetic maculopathy). The OCT eye scanner is also being reached for before planned cataract removal and artificial lens implantation. It is invaluable when monitoring glaucoma lesions. OCT examination is standardly used to diagnose the condition of the cornea before and after procedures

With OCT, it is possible to assess the condition of the anterior and posterior parts of the eyeball, including the cornea, the angle of the eye, the macula, the optic nerve, and the retina.

OCT of the anterior segment of the eye gives an image similar to that of UBM (ultrabiomicroscopy), except that UBM is a tactile examination – a special flexible container (known as a corneal cap) filled with fluid is placed over the anesthetized eye, in which the probe tip is immersed without touching the eye – and OCT is non-contact. The disadvantage of the UBM test is the shallow depth (about 5 mm) to which such an ultrasound beam can penetrate deep into tissue. OCT is more accurate.

OCT examination requires injecting the patient into the conjunctival sac with a pupil dilator.

We distinguish between OCT

  • of the anterior segment of the eye
    • visualization similar to UBM except that it is more accurate and non-contact, such as visualization of the cornea, pachymetry, visibility of corneal scars, lens transparency, lens thickness , seepage (important in glaucoma), depth profile and volume of the anterior chamber of the eye
  • rear

    • OCT of the optic nerve and the thickness of the fibers around this nerve

Optical coherence tomography of the eye, also known as optical coherence tomography (OTC), can be performed with the Retina Scan Duo ™. It’s a high-resolution OCT and funduscamera (imaging the fundus of the eye through the pupil) in one. The advantages of the device are:

  • Easy operation with automatic 3D eye tracking, automatic measurement and user-friendly software. Automatic 3D tracking and automatic shooting functions allow easy imaging of the fundus and all its functions. Each standard and professional mode has a different image capture interface that can be selected according to your needs.
  • Retina Scan Duo’s stereo and panorama photography enables navigation of stereo and panoramic photography with target markers displayed on the observation screen, allowing the operator to easily capture stereo images and panoramic compositions.
  • High image resolution – Retina Scan Duo ™ has a built-in 12-megapixel CCD camera (averaging 50 HD images).
  • Wide scanning area (12mmx9mm) and Normative Database imaged with large area color map (9mm x 9mm).
  • 8 OCT scanning templates.
  • FAF mode for automated fluorescein angiography (fundus autofluorescence). FAF This is an advanced screening function and a non-invasive method for evaluating the RPE without contrast dye. The feature is helpful in detecting the early stages of retinal disorders.
  • Compact design.

The most important thing is to choose the right method for your visual impairment. During the initial consultation, we will suggest an appropriate laser correction technique.
