Enhanced depth imaging optical coherence tomography.
Imaging the choroid with conventional commercial spectral-domain optical coherence tomography (SD-OCT) has been difficult, mainly because of difficulty in signal transmission beyond the retinal pigment epithelium. A recent modification to the standard technique, termed enhanced depth imaging optical coherence tomography (EDI-OCT), was able to image the choroid with reasonable clarity using comm...
متن کاملRetrobulbar structure visualization with enhanced depth imaging optical coherence tomography.
PURPOSE To assess enhanced depth imaging optical coherence tomography (EDI-OCT) visualization of deep posterior pole structures and retrobulbar tissues in myopic eyes and evaluate ocular structural elements that influence this capability. METHODS Thirty consecutive myopic eyes (>-6 diopters) from 21 patients were enrolled. Exclusion criteria included any pathological condition affecting the p...
متن کاملEnhanced optical clearing of skin in vivo and optical coherence tomography in-depth imaging.
The strong optical scattering of skin tissue makes it very difficult for optical coherence tomography (OCT) to achieve deep imaging in skin. Significant optical clearing of in vivo rat skin sites was achieved within 15 min by topical application of an optical clearing agent PEG-400, a chemical enhancer (thiazone or propanediol), and physical massage. Only when all three components were applied ...
متن کاملAgreement Between Three Optical Coherence Tomography Devices to Assess the Insertion Distance and Thickness of Horizontal Rectus Muscles.
PURPOSE To assess the agreement between two different spectral domain (SD-OCT) and one swept source (SS-OCT) optical coherence tomography device to measure the insertion distance and the thickness of the horizontal rectus muscles. METHODS Seventy eyes from 35 healthy patients were studied. Three OCT instruments-Spectralis (Heidelberg Engineering Inc., Heidelberg, Germany), Cirrus 5000 (Carl Z...
متن کاملLong-wavelength optical coherence tomography at 1.7 microm for enhanced imaging depth.
Multiple scattering in a sample presents a significant limitation to achieve meaningful structural information at deeper penetration depths in optical coherence tomography (OCT). Previous studies suggest that the spectral region around 1.7 microm may exhibit reduced scattering coefficients in biological tissues compared to the widely used wavelengths around 1.3 mum. To investigate this long-wav...
