    2. Artifacts on the Optic Nerve Head Analysis of the Optical Coherence Tomography in Glaucomatous and Nonglaucomatous Eyes

      Purpose: To determine the frequency and type of imaging artifacts in the optic nerve head (ONH) analysis protocol of the optical coherence tomograph (Stratus OCT) in healthy and glaucomatous eyes. Design: Retrospective study. Methods: Two experienced operators reviewed imaging obtained in 264 eyes from 264 participants (146 controls, 118 glaucoma patients). Each participant had a minimum of 3 scans using fast ONH protocol. Only scans with good quality were included ...

    3. Optical coherence tomography: a window into the mechanisms of multiple sclerosis

      Optical coherence tomography: a window into the mechanisms of multiple sclerosis
      The pathophysiology of multiple sclerosis (MS) is characterized by demyelination, which culminates in a reduction in axonal transmission. Axonal and neuronal degeneration seem to be concomitant features of MS and are probably the pathological processes responsible for permanent disability in this disease. The retina is unique within the CNS in that it contains axons and glia but no myelin, and it is, therefore, an ideal structure within which to visualize ...

    4. Adaptive Optics Scanning Laser Ophthalmoscopy Images Demonstrate Abnormal Cone Structure in a Family with the Mitochondrial DNA T8993C Mutation

      Purpose: To study the effect of mitochondrial DNA (mtDNA) mutation T8993C on cone structure in a family expressing neurogenic muscle weakness, ataxia, retinitis pigmentosa (NARP) syndrome. Methods: Five family members were studied, using clinical examination, nerve conduction studies, perimetry, optical coherence tomography (OCT) measures of central retinal thickness and electroretinography. High-resolution images of cone structure using adaptive optics scanning laser ophthalmoscopy (AOSLO) were obtained in 4 subjects with stable fixation ...

    5. Reproducibility of Optical Coherence Tomography in Multiple Sclerosis

      Background  Optical coherence tomography (OCT) is a promising new method of quantifying axon thickness in the retinal nerve fiber layer (RNFL) that has been used predominantly by ophthalmologists to monitor glaucoma. Optical coherence tomography is being considered as a potential outcome measure in multiple sclerosis (MS) clinical trials, but no data exist on the reproducibility of this technique in MS centers.Objective  To determine the reproducibility of OCT measurement of ...

    6. Retinal Imaging by Laser Polarimetry and Optical Coherence Tomography Evidence of Axonal Degeneration in Multiple Sclerosis

      Background Optical coherence tomography (OCT) and scanning laser polarimetry with variable corneal compensation (GDx) are similar yet provide information on different aspects of retinal nerve fiber layer (RNFL) structure (thickness values similar to histology for OCT vs birefringence of microtubules for GDx). Objectives To compare the ability of OCT and GDx to distinguish eyes of patients with multiple sclerosis (MS) from eyes of disease-free controls and thus identify RNFL abnormalities ...

    7. Optical coherence tomography and disease subtype in multiple sclerosis.

      OBJECTIVE: To examine retinal nerve fiber layer (RNFL) thickness, macular volumes (MV), and visual acuity in multiple sclerosis (MS) eyes, with and without history of acute optic neuritis (ON). METHODS: RNFL thickness was measured in 326 MS and 94 control eyes using optical coherence tomography (OCT). MV and vision testing were done in a subset of the cohort. MS subtype was classified as relapsing-remitting (RRMS, n = 135), primary progressive (PPMS ...

  2. About University of Alabama

    University of Alabama

    The University of Alabama (also known as Alabama, UA, or colloquially as 'Bama) is a public coeducational university located in Tuscaloosa, Alabama, USA. Founded in 1831, UA is the flagship school of the University of Alabama System. Within Alabama, it is often called the Capstone. UA is the senior and the largest in terms of enrollment of the state's major research universities, the others being academic and athletic rival Auburn University and fellow UA System institutions the University of Alabama in Huntsville (UAH) and the University of Alabama at Birmingham (UAB). Outside the state, it is well known for the fact that its athletic teams are nicknamed the "Crimson Tide" (crimson being one of the school colors).   The University of Alabama offers programs of study in 12 academic divisions leading to bachelor's, master's, Education Specialist, and doctoral degrees. The only publicly-supported law school in Alabama is at UA. Other academic programs unavailable elsewhere in Alabama include doctoral programs in anthropology, library and information studies, metallurgical and material engineering, music, Romance languages, and social work.  As of fall 2007, Alabama has an enrollment of 25,580 students and its president is Dr. Robert Witt. The University of Alabama has the highest ranking in the 2008 edition of the US News and World Report: America's Best Colleges of any university in the state of Alabama."
