    Abstract

    We present clinical data obtained with the aid of a novel instrumentation using, high speed, ultrahigh resolution Spectral/Fourier domain Optical Coherence Tomography (SOCT). This method allows performing video rate, ultrahigh resolution cross-sectional images with 98 dB of sensitivity, 100 times faster that previously reported UHR OCT system with comparable axial resolution of 3 um. Ultrahigh resolution imaging enables improved visualization of retinal architectural morphology compared to standard resolution OCT. High speed, ultrahigh resolution OCT using Spectral/Fourier domain detection promises to significantly enhance the utility of OCT for clinical applications. High speed imaging enables high density data sets to be acquired which can increase the quality of reconstructed cross-sectional images and can help to visualize small focal pathologic changes. This technique helps reconstructing true retinal topography without motion artifacts. Submitted manuscript describes the technology, its clinical performance and present preliminary data obtained for various retinal pathologies.
