Angio – OCT

3D DRI OCT Triton plus (AngioOCT)
Angio-OCT – a new, non-invasive method for imaging the flow in the retinal vessels Angio-OCT is a test that includes both angiography and high-resolution OCT. It enables early detection of pathologies within the vessels at different levels of the retina. It is a non-invasive test and can be safely repeated even many times. Unlike traditional vascular imaging methods, such as fluorescein and indocyanine angiography, Angio Oct does not require any dye or special preparation. En face images allow you to view angiograms from the intima up to the choroid, which allows you to assess the vascular plexus, fragments of the inner choroid, outer retina, choriocapillaries, and other areas. The examination takes only a few minutes.

Swept Source (SS OCT) technology provides new possibilities in the field of imaging of eye structures. Compared to the most widely distributed spectral devices (SOCT) at present, it allows for a much faster scanning speed, much better penetration of the eye structures up to the sclera and a better final resolution of the obtained images. The use of 1050 nm (infrared) wavelength in the SS OCT TRITON provides much better tissue penetration than the red light used in SOCT. The infrared light is also scattered less, which enables better visualization of the posterior vitreous cortex and its structure. Moreover, in SOCT devices a significant limitation in the imaging of eye structures is the spectrometer, whose non-linear sensitivity characteristics further limit the possibility of obtaining a good-quality scan simultaneously in the choroid and vitreous. Swept Source technology does not require the use of a spectrometer.

Thanks to the properties described above, the swept source DRI OCT TRITON is a device that allows you to look deeper into the structures of the human eye.

Gives possibility:

  • simultaneous high-quality image of the vitreous, retina, choroid and sclera
  • visualization of the vitreous with the possibility of visualizing the diversity of its structure
  • automatic creation of maps of the thickness and volume of the retinal and choroid layers
  • obtaining a much better quality of OCT scans in patients with reduced transparency of optical centers, including cataracts and unfavorable refractive errors
  • Thanks to the large maximum width of scans (12mm), the camera can simultaneously image the macular area and the nerve disc
  • high transmittance and low light scattering allow for obtaining high-quality, artifact-free sections of the anterior segment.

An additional advantage of using infrared light in the examination is the lack of scanning lines visible to the patient, which often result in loss of fixation and deterioration of the examination quality.

The TRITON apparatus simultaneously with the OCT slices takes color images of the fundus correlated with the scans, which can be replaced with an autofluorescence photo (autofluo function and fluorescein angiography are available in the TRITON (plus) apparatus). The device has extensive glaucoma functions with a normative database. Thanks to the large scanning area (maximum 12 × 9 mm), it is possible to perform imaging and qualitative diagnostics of the macular area in one scan, measure the thickness of the layer of nerve fibers around the disc, ganglion cells in the central area and obtain topographic data of the optic disc.

Spectral tomography of the retina

Study characteristics:
Spectral retinal tomography (SOCT) is a device that has revolutionized the diagnosis of eye diseases. Imaging of eye tissues in a cross-section comparable to the histological image is an invaluable diagnostic tool in the examination of both the anterior and posterior segments of the eyeball.


  • Retinal imaging in 2D and 3D projection
    OCT cross-sections made with the OCT-2000 3D tomograph perfectly illustrate the structure of the vitreous body and the retina. It is possible to assess the thickness of individual anatomical structures, as well as a comparative assessment of the condition of the retina at subsequent visits.
  • Fundus photos
    Built-in fundus camera with a high-quality digital camera (16.2 Mpx) complements SOCT diagnostics, allowing you to visualize the structure of the eye in detail and reveal any pathological changes.
  • Glaucoma profile
    The glaucoma module makes it possible to perform a fully automated topography of the optic disc and compare it with a normative database. The glaucoma module, supplemented by the analysis of the ganglion cells and the measurement of the filtration angle, is a complete imaging tool. The test allows to estimate the average thickness of RNFL nerve fibers (retinal nerve fiber layer), which is used primarily in the diagnosis of glaucoma, but also in demyelinating diseases (e.g. sclerosis multiplex).
  • Anterior Eye Scanning:
    Various analytical functions in conjunction with color photography and 3D SOCT imaging enable imaging and analysis of the cornea, anterior segment of the eye (e.g. assessment of keratoconus, drainage angle, measurement of corneal thickness, assessment of the cornea after refractory procedures).

The course of the study:
The test is performed in a sitting position, most often after pupil dilation, although it can also be performed without dilating the pupils (with horizontal optical centers). The patient receives a tomography of the eye with a description immediately after the examination. Estimated duration of the study with description: 40 minutes.

SOCT is a non-invasive, safe test that can be performed multiple times.

Color photo of the eye

Fundus camera 3D OCT 2000 (Topcon)
Color photography of the anterior segment and the fundus is valuable medical documentation. Thanks to the photos, it is easier to assess the progression of lesions


Study characteristics:
It allows the assessment of the field of central and peripheral vision.

They are performed routinely in the diagnosis of glaucoma, but also in diseases of the optic nerve and central nervous system damage.

The course of the study:

  • The examined person looks at the central point of the apparatus canopy. At the same time, points of light of different intensity appear circumferentially. The patient’s task is to press the remote control button every time he notices light points appearing circumferentially.
  • The patient receives the test result immediately after it has been conducted
  • Estimated duration of the study: 30-40 minutes.


Topcon TRK 1P
Basic ophthalmological examination allowing the examination of the eye refraction and corneal power in the main optical axes.


Tonometer (Topcon TRK 1P)
The level of intraocular pressure is a factor that allows to assess the risk of glaucoma and is therefore of critical importance in the diagnosis and treatment of this disease. The Topcon TRK 1P non-contact tonometer with corneal response technology takes into account the biomechanical properties of the cornea by providing the value of the Corneal Compensated IOPcc (Corneal Compensated) pressure – a pressure that is significantly less error-prone than other tonometry methods. The addition of the value of correlated pressure (Goldmann Corelated) gives the opportunity to better understand tonometry, which translates into more accurate diagnoses and decisions regarding the therapy. It allows the assessment of the actual intraocular pressure.


Examination of the filtration angle.
The test is performed in patients with suspected glaucoma.


Useful in the diagnosis of glaucoma, in the implantation of intracorneal rings, in corneal degeneration.
