      Retinal thickness measured with optical coherence tomography and risk of disability worsening in multiple sclerosis: a cohort study
      Background Most patients with multiple sclerosis without previous optic neuritis have thinner retinal layers than healthy controls. We assessed the role of peripapillary retinal nerve fibre layer (pRNFL) thickness and macular volume in eyes with no history of optic neuritis as a biomarker of disability worsening in a cohort of patients with multiple sclerosis who had at least one eye without optic neuritis available. Methods In this multicentre, cohort study ...

      Voxel based morphometry in optical coherence tomography: validation and core findings
      Optical coherence tomography (OCT) of the human retina is now becoming established as an important modality for the detection and tracking of various ocular diseases. Voxel based morphometry (VBM) is a long standing neuroimaging analysis technique that allows for the exploration of the regional differences in the brain. There has been limited work done in developing registration based methods for OCT, which has hampered the advancement of VBM analyses in ...

      Simultaneous segmentation of retinal surfaces and microcystic macular edema in SDOCT volumes
      Optical coherence tomography (OCT) is a noninvasive imaging modality that has begun to find widespread use in retinal imaging for the detection of a variety of ocular diseases. In addition to structural changes in the form of altered retinal layer thicknesses, pathological conditions may also cause the formation of edema within the retina. In multiple sclerosis, for instance, the nerve fiber and ganglion cell layers are known to thin. Additionally ...

      Combined registration and motion correction of longitudinal retinal OCT data
      Optical coherence tomography (OCT) has become an important modality for examination of the eye. To measure layer thicknesses in the retina, automated segmentation algorithms are often used, producing accurate and reliable measurements. However, subtle changes over time are difficult to detect since the magnitude of the change can be very small. Thus, tracking disease progression over short periods of time is difficult. Additionally, unstable eye position and motion alter the ...

      Optical Coherence Tomography in Neurologic Disease (Textbook)
      Shortly after the invention of the first two-dimensional optical coherence tomography (OCT) scans by James Fujimoto and colleagues at the Massachusetts Institute of Technology in 1991, ophthalmologists recognized the extraordinary potential for OCT to facilitate quantitative assessment of the neuroretina. OCT rapidly became a commonplace tool in ophthalmologic practice to identify both inflammatory and degenerative conditions affecting the optic nerve and retina. The utility of OCT to detect and quantify ...

      Microcystic macular edema (MME) is a term used to describe pseudocystic spaces in the inner nuclear layer (INL) of the human retina. It has been noted in multiple sclerosis (MS) as well as a variety of other diseases. The processes that lead to MME formation and their change over time have yet to be explained sufficiently. The low rate at which MME occurs within such diverse patient groups makes the ...

  6. Quotes

    1. The eye is the window into the brain and by measuring how healthy the eye is, we can determine how healthy the rest of the brain is...Eye scans are not that expensive, are really safe, and are widely used in ophthalmology, and now that we have evidence of their predictive value in MS, we think they are ready for prime time. We should be using this new quantitative tool to learn more about disease progression, including nerve damage and brain atrophy.
