    1. Optical coherence tomography reflects brain atrophy in multiple sclerosis: A four-year study

      Optical coherence tomography reflects brain atrophy in multiple sclerosis: A four-year study

      Objective The aim of this work was to determine whether atrophy of specific retinal layers and brain substructures are associated over time, in order to further validate the utility of optical coherence tomography (OCT) as an indicator of neuronal tissue damage in patients with multiple sclerosis (MS). Methods Cirrus high-definition OCT (including automated macular segmentation) was performed in 107 MS patients biannually (median follow-up: 46 months). Three-Tesla magnetic resonance imaging brain scans (including brain-substructure volumetrics) were performed annually. Individual-specific rates of change in retinal and brain measures (estimated with linear regression) were correlated, adjusting for age, sex, disease duration, and ...

      Optical coherence tomography reflects brain atrophy in MS: A four year study

      Objective : To determine whether atrophy of specific retinal layers and brain substructures are associated over time, in order to further validate the utility of optical coherence tomography (OCT) as an indicator of neuronal tissue damage in patients with multiple sclerosis (MS). Methods : Cirrus high definition OCT (including automated macular segmentation) was performed in 107 MS patients biannually (median follow-up: 46-months). Three-tesla magnetic resonance imaging brain scans (including brain-substructure volumetrics) were performed annually. Individual-specific rates of change in retinal and brain measures (estimated with linear regression) were correlated, adjusting for age, sex, disease duration, and optic neuritis (ON) history. Results : Rates ...

    3. In Vivo Demonstration of Homonymous Hemimacular Loss of Retinal Ganglion Cells Due to a Thalamic Lesion Using Optical Coherence Tomography

      In Vivo Demonstration of Homonymous Hemimacular Loss of Retinal Ganglion Cells Due to a Thalamic Lesion Using Optical Coherence Tomography

      A previously healthy 40-year-old woman presented with subacute onset of a left homonymous hemianopia. Contrast-enhanced magnetic resonance imaging of the brain revealed a T2-hyperintense lesion in the right thalamus, with associated subtle gadolinium enhancement ( Figure 1 ), and a small periventricular lesion. Although her visual symptoms were improving, a new left-sided hemiparesis developed 3 weeks later. Additional magnetic resonance imaging of the brain showed extension of the original thalamic lesion into the right internal capsule, with persistent contrast enhancement. Her visual and motor symptoms gradually improved over 3 months.
