Summary

Comparison of high-resolution optical coherence tomography (High-Res-OCT) to conventional imaging modalities for the diagnosis of eye diseases

Detailed description

The high resolution optical coherence tomography (High-Res-OCT) is an improvement of a non-invasive routinely used imaging technique, the optical coherence tomography (OCT), with a light-source capable of providing an increased axial resolution. The routinely used Spectral-Domain OCT has a center wavelength of 880 nm and a spectral bandwidth of 40 nm, resulting in an axial resolution of approximately 7 μm in the eye and is used routinely worldwide. The High-Res OCT works with a central wavelength of 840 nm and an increased bandwidth of 130 nm, making it possible to improve the optical axial resolution in tissue from 7 to 3 µm, without increasing the maximum laser exposure limit. The improved axial resolution of the High-Res OCT results in clearer and more detailed images. The technique is routinely used in clinical practice and the device used for High-Res-OCT (Heidelberg, SPECTRALIS® High-Res OCT- DMR001) has received CE mark (european conformity in the extended Single Market in the European Economic Area) approval in March 2021. We plan to compare High-Res-OCT as an imaging modality to conventional imaging modalities used in clinical routine, such as the Spectral-Domain-OCT (SD-OCT)
