    3. The potential of spectral domain optical coherence tomography imaging based retinal biomarkers

      The potential of spectral domain optical coherence tomography imaging based retinal biomarkers
      Background Biomarker, a merged word of biological marker, refers to a broad subcategory of medical signs that objectively indicate the state of health, and well-being of an individual. Biomarkers hold great promise for personalized medicine as information gained from diagnostic or progression markers can be used to tailor treatment to the individual for highly effective intervention in the disease process. Optical coherence tomography (OCT) has proved useful in identifying various ...

    5. Spectral Domain Optical Coherence Tomography Features and Classification Systems for Diabetic Macular Edema: A Review

      Spectral Domain Optical Coherence Tomography Features and Classification Systems for Diabetic Macular Edema: A Review
      Abstract: Spectral domain optical coherence tomography (SD-OCT) is fast becoming the current standard of care for the detection and assessment of diabetic macular edema. With the application of SD-OCT for imaging of retinal microstructure and measurement of retinal thickness, new information regarding disease characteristics has been gathered, which was unrecognized previously. Retinal thickness measurements on SD-OCT have also been used for deciding the management and monitoring of the disease. Since ...

      Spectral Domain Optical Coherence Tomography Based Alterations in Macular Thickness and Inner Segment Ellipsoidare Associated with Severity of Diabetic Retinopathy
      Objective: To study the association of spectral domain optical coherence tomography (SD-OCT) based alterations in macular thickness and inner segment-ellipsoid band (ISel) with severity of retinopathy in cases of type 2 diabetes mellitus. Method: Two hundred thirty eight consecutive cases and seventy nine healthy controls were included. Eyes of cases were divided into three groups according to ETDRS classification: diabetes without retinopathy (No DR) (n=79), non-proliferative diabetic retinopathy (NPDR ...

    9. Three-dimensional spectral domain optical coherence tomography in vitreomacular traction

      Three-dimensional spectral domain optical coherence tomography in vitreomacular traction
      Spectral domain optical coherence tomography (SD-OCT) is a non-invasive tool providing unprecedented imaging and analysis of vitreomacular interface. Two cases of vitreomacular traction were analysed by advanced threedimensional (3D) SD-OCT imaging. En-face OCT permitted localisation of the exact point of attachment of vitreous to retina. A comprehensive view of the surface topography and anatomical configuration of vitreomacular affection was revealed by 3D imaging with segmentation technique. Macular change analysis programme ...

    10. Three-dimensional spectral domain optical coherence tomography in chronic exposure to welding arc

      Three-dimensional spectral domain optical coherence tomography in chronic exposure to welding arc
      Three-dimensional spectral domain optical coherence tomography was performed in a 26-year-old man with chronic exposure to welding arc. Advanced macular visualisation provided significant findings of inner segment-ellipsoid zone disruption with the presence of cystoid changes and hyper-reflective material in the area of disruption. The external limiting membrane was intact in both the eyes. C-scan retinal pigment epithelium fit map of the left eye revealed a well-delineated defect whereas the right ...

      Three-dimensional spectral domain optical coherence tomography in X linked foveal retinoschisis
      Spectral domain optical coherence tomography (SD-OCT) was performed in two cases of bilateral X linked foveal retinoschisis of different age groups. On fundus examination spoke wheel and honeycomb pattern of cysts were observed along with retinal nerve fibre layer (RNFL) defects. On SD-OCT, schisis was observed in the outer plexiform layer. External limiting membrane disruption was observed in the subfoveal area, along with disruption of outer nuclear layer (ONL) and ...
