    4. Atlas of Pathologic Myopia (Textbook)

      Atlas of Pathologic Myopia (Textbook)

      The choroid in high myopia is markedly thin compared to normal eyes. Choroidal thickness is negatively correlated with severity of myopic maculopathy from tessellated fundus to macular diffuse choroidal atrophy. However, there is no significant difference in choroidal thickness between eyes with macular diffuse choroidal atrophy and patchy choroidal atrophy. By using swept-source OCT, macular Bruch’s membrane defects in patchy atrophy and CNV-related macular atrophy have also been shown. Using receiver operating characteristic curve, the cut-off value of 56.5 μm for the nasal choroidal thickness (3000 μm from fovea) is able to predict peripapillary diffuse choroidal atrophy from ...

    19. Imaging of Intraocular Tumours (Book Chapter)

      Imaging of Intraocular Tumours (Book Chapter)

      Ophthalmology is a specialty that is very reliant on imaging, since the optically optimized structure of the eye lends itself easily to evaluation with photographic, optical and even ultrasound imaging. In ocular oncology, ophthalmologists have the advantage by and large over other cancer physicians of being able to visualize the tumour they are dealing with and to use imaging to record and diagnose the lesion, without always having to take a tissue biopsy. With ever improving resolution this has even led to the concept of the “optical biopsy” using the increasing resolution of optical coherence tomography. For some diagnoses, such ...

    20. Optical Coherence Tomography for Imaging Dental Caries (Book Chapter)

      Optical Coherence Tomography for Imaging Dental Caries (Book Chapter)

      Optical Coherence tomography (OCT) is a noninvasive technique that can be used to measure reflectivity within dental hard tissues. Due to the strong reflection at the tooth surfaces, the contrast between sound and demineralized tissues can be enhanced by use of polarization. Polarized sensitive OCT (PS-OCT) can monitor demineralization and remineralization. Clinical studies have indicated that OCT was able to demonstrated penetration into DEJ more reliably that radiographs in questionable occlusal caries. In root caries, the system was able to discriminate sound dentin from demineralized dentin, assess cementum thickness and determine lesion severity by using shrinkage of dentin as a ...

      High Resolution Imaging in Microscopy and Ophthalmology New Frontiers in Biomedical Optics (Textbook)

      Optical coherence tomography (OCT) is a non-invasive technique for cross-sectional tissue imaging. It typically uses light in the near-infrared spectral range which has a penetration depth of several hundred microns in tissue. The backscattered light is measured with an interferometric set-up to reconstruct the depth profile of the sample at the selected location. A scanning OCT beam allows for acquisition of cross-sectional images of the tissue structure. Different technical methods are introduced and compared regarding their properties like sensitivity, imaging speed and penetration depth. Regardless of the technical realization, axial resolution and imaging range of an OCT system are determined ...

    23. What’s New in Optical Coherence Tomography Angiography for Glaucoma (Book Chapter)

      What’s New in Optical Coherence Tomography Angiography for Glaucoma (Book Chapter)

      Glaucoma is one of the main clinical areas where OCT angiography is used. In contrast to medical retinal application, where qualitative image analysis and semiquantitative measurements are frequently satisfactory for clinical decision-making, in glaucoma the exact quantitative measurements provide the useful information. Therefore both general ophthalmologists who treat glaucoma patients and glaucoma subspecialists need to be familiar with the measurement details of OCT angiography, the types of complementary structural information necessary to clinical decision-making, and the current limitations of the technology. This chapter attempts to guide the reader through all aspects of glaucoma-related OCT angiography in a stepwise manner.
