    2. Projection OCT fundus imaging for visualising outer retinal pathology in non-exudative age-related macular degeneration

      Aims: To demonstrate ultrahigh-resolution, three-dimensional optical coherence tomography (3D-OCT) and projection OCT fundus imaging for enhanced visualisation of outer retinal pathology in non-exudative age-related macular degeneration (AMD). Methods: A high-speed, 3.5 µm resolution OCT prototype instrument was developed for the ophthalmic clinic. Eighty-three patients with non-exudative AMD were imaged. Projection OCT fundus images were generated from 3D-OCT data by selectively summing different retinal depth levels. Results were compared with ...

    7. Three-Dimensional Optical Coherence Tomography (3D-OCT) Image Enhancement with Segmentation-Free Contour Modeling C-Mode

      PURPOSE. To develop a semiautomated method to visualize structures of interest (SoIs) along their contour within three-dimensional, spectral domain optical coherence tomography (3D SD-OCT) data, without the need for segmentation. METHODS. With the use of two SD-OCT devices, the authors obtained 3D SD-OCT data within 6 x 6 x 1.4-mm and 6 x 6 x 2-mm volumes, respectively, centered on the fovea in healthy eyes and in eyes with ...

    8. Spectral domain optical coherence tomography in patients with nystagmus

      Purpose: To evaluate the feasibility of spectral domain optical coherence tomography (SD-OCT) macular scanning in nystagmus patients and to introduce this technology as a means of simultaneously studying the afferent and efferent visual system of this unique population. Methods: Prospective analysis of nystagmus patients who underwent complete clinical and electrophysiological evaluation was performed in this single-center, noncomparative study. Three macular three-dimensional cube scans per eye (200 × 200 × 1024 samplings in ...

    9. Imaging of the retinal nerve fibre layer for glaucoma

      Background: Glaucoma is a group of diseases characterised by retinal ganglion cell dysfunction and death. Detection of glaucoma and its progression are based on identification of abnormalities or changes in the optic nerve head (ONH) or the retinal nerve fibre layer (RNFL), either functional or structural. This review will focus on the identification of structural abnormalities in the RNFL associated with glaucoma. Discussion: A variety of new techniques have been ...

    10. Retinal vessel segmentation on SLO image

      A scanning laser ophthalmoscopy (SLO) image, taken from optical coherence tomography (OCT), usually has lower global/local contrast and more noise compared to the traditional retinal photograph, which makes the vessel segmentation challenging work. A hybrid algorithm is proposed to efficiently solve these problems by fusing several designed methods, taking the advantages of each method and reducing the error measurements. The algorithm has several steps consisting of image preprocessing, thresholding ...

    11. Diagnostic Tools for Glaucoma Detection and Management

      Early diagnosis of glaucoma is critical to prevent permanent structural damage and irreversible vision loss. Detection of glaucoma typically relies on examination of structural damage to the optic nerve combined with measurements of visual function. To aid the clinician in evaluation of visual function and structure, computer-based devices such as confocal scanning laser ophthalmoscopy, scanning laser polarimetry, and optical coherence tomography provide quantitative assessments of structural damage, and visual function ...

    1. It's the most rapidly adopted ophthalmic technology in history.
      In How OCT innovations changing glaucoma care
    2. OCT will be able to detect glaucomatous abnormalities prior to our current functional measurement technology being able to detect them, and the earlier in the disease that you can detect damage or progression, the more likely it is you are able to prevent further progression with less intensive intervention.
      In Emerging technologies open new horizons in glaucoma structural evaluation, management
    3. I’m delighted by the Champalimaud Foundation’s recognition of our efforts...We continue to work on improving OCT and in the next decade, it could be as portable and easy to use as a standard ophthalmoscope.
      In Joel S. Schuman, M.D., Part of Team Receiving António Champalimaud Vision Award
    4. That gives the promise to better track progression to detect change over time, and that is really a big advance in terms of changes from time-domain OCT.
      In OCT devices increasingly finding use outside retinal practice
    5. You can look for characteristic nerve fiber layer abnormalities that are seen in glaucoma and these will show up as arcuate abnormalities — deviations from normal — on the deviation map of the spectral-domain OCT.
      In OCT devices increasingly finding use outside retinal practice
    6. With imaging we have much younger technology. The progression assessments with these technologies seem to be more sensitive than functional assessment, but they don't necessarily overlap with functional assessment or even with each other.
      In Better Glaucoma Progression Tracking
    7. I think that in future iterations we will be able to have focal assessment of change, looking at the overall trend as in regression, but also looking at event analysis, analogous to the GPA on visual field.
