Recent Submissions

  • Are high lags of accommodation in myopic children due to motor deficits? 

    Labhishetty, Vivek; Bobier, William (Elsevier, 2017-01)
    Children with a progressing myopia exhibit an abnormal pattern of high accommodative lags coupled with high accommodative convergence (AC/A) and high accommodative adaptation. This is not predicted by the current models ...
  • Unmasking the linear behaviour of slow motor adaptation to prolonged convergence 

    Erkelens, Ian; Thompson, Benjamin; Bobier, William; Munoz, Doug (Wiley, 2016-06)
    Adaptation to changing environmental demands is central to maintaining optimal motor system function. Current theories suggest that adaptation in both the skeletal-motor and oculomotor systems involves a combination of ...
  • Development of an Arabic Continuous Text Near Acuity Chart 

    Alabdulkader, Balsam (University of Waterloo, 2017-04-24)
    Purpose: Near visual acuity is an essential measurement during an oculo-visual assessment. Continuous text near visual acuity charts measure reading acuity and other aspects of reading performance. Arabic is ranked as the ...
  • Retinal perfusion changes in radiation retinopathy-post brachytherapy for choroidal melanoma

  • The Development of an Antibody-Drug Conjugate to Specifically Target and Soften the Crystalline Lens in vivo 

    Won, Gah-Jone (University of Waterloo, 2017-04-04)
    Helmholtz’s classical theory of accommodation states that, within the eye, contraction of the annular ciliary muscle releases the passive tension of zonules that hold the lens in a flattened state. As a result, the surface ...
  • Neonatal Glycemia and Neurodevelopmental Outcomes at 2 Years

Geoffrey; Gamble, Gregory D.; Harris, Deborah L.; Jacobs, Robert J.; Jiang, Yannan; Paudel, Nabin; Signal, Matthew; Thompson, Benjamin; Wouldes, Trecia A.; Yu, Tzu-Ying; Harding, Jane E. (Massachusetts Medical Society, 2015-10-15)
    Neonatal hypoglycemia is a common and readily treatable risk factor for neurologic impairment in children. Although associations between prolonged symptomatic neonatal hypoglycemia and brain injury are well established,1 ...
  • Multisensory attention training for treatment of tinnitus

    Tinnitus is the conscious perception of sound with no physical sound source. Some models of tinnitus pathophysiology suggest that networks associated with attention, memory, distress and multisensory experience are involved ...
  • Fatigue related impairments in oculomotor control are prevented by caffeine 

    Connell, Charlotte J. W.; Thompson, Benjamin; Kuhn, Gustav; Claffey, Michael P.; Duncan, Shelley; Gant, Nicholas (Nature, 2016-05-25)
    Strenuous exercise can result in an inability of the central nervous system to drive skeletal muscle effectively, a phenomenon known as central fatigue. The impact of central fatigue on the oculomotor system is currently ...
  • MRI guided brain stimulation without the use of a neuro-navigation system. 

    Vaghefi, Ehsan; Cai, Peng; Fang, Fang; Byblow, Winston D.; Stinear, Cathy M.; Thompson, Benjamin (Hindawi Publishing, 2015-01-01)
    A key issue in the field of noninvasive brain stimulation (NIBS) is the accurate localization of scalp positions that correspond to targeted cortical areas. The current gold standard is to combine structural and functional ...
  • Fine Motor Skills of Children With Amblyopia Improve Following Binocular Treatment 

    Webber, Ann L.; Wood, Joanne M.; Thompson, Benjamin (Association for Research in Vision and Ophthalmology, 2016-09-08)
    Purpose: The purpose of this study was to determine whether reduced fine motor skills in children with amblyopia improve after binocular treatment and whether improvements are sustained once treatment has ceased. Methods: ...
  • Fluoxetine Does Not Enhance Visual Perceptual Learning and Triazolam Specifically Impairs Learning Transfer 

    Lagas, Alice K.; Black, Joanna M.; Byblow, Winston D.; Fleming, Melanie K.; Goodman, Lucy K.; Kydd, Robert R.; Russell, Bruce R.; Stinear, Cathy M.; Thompson, Benjamin (Frontiers Media, 2016-10-19)
    The selective serotonin reuptake inhibitor fluoxetine significantly enhances adult visual cortex plasticity within the rat. This effect is related to decreased gamma-aminobutyric acid (GABA) mediated inhibition and identifies ...
  • Exercise-Induced Fatigue and Caffeine Supplementation Affect Psychomotor Performance but Not Covert Visuo-Spatial Attention 

    Connell, Charlotte J. W.; Thompson, Benjamin; Kuhn, Gustav; Gant, Nicholas (Public Library of Science, 2016-10-21)
    Fatigue resulting from strenuous exercise can impair cognition and oculomotor control. These impairments can be prevented by administering psychostimulants such as caffeine. This study used two experiments to explore the ...
  • The Effects of tDCS Across the Spatial Frequencies and Orientations that Comprise the Contrast Sensitivity Function 

    Richard, Bruno; Johnson, Aaron P.; Thompson, Benjamin; Hansen, Bruce C. (Frontiers Media, 2015-11-27)
