    • 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 ...
    • Binocular Adaptation to +2 D Lenses in Myopic and Emmetropic Children: 

      Sreenivasan, Vidhyapriya; Irving, Elizabeth; Bobier, William (Wolters Kluwer, 2009-06)
      Purpose. To compare vergence adaptation to +2 D addition lenses in myopic and emmetropic children and to evaluate the influence of the accommodative-vergence crosslink (AC/A ratio) on this adaptation. Methods. Nine ...
    • Binocular adaptation to near addition lenses in emmetropic adults 

      Sreenivasan, Vidhyapriya; Irving, Elizabeth; Bobier, William (Elsevier, 2008-05)
      Near addition lenses are prescribed to pre-presbyopic individuals for treatment of binocular motor problems such as convergence excess and to control the progression of myopia. To date, no investigation has looked at the ...
    • Binocular treatment of amblyopia using videogames (BRAVO): study protocol for a randomised controlled trial 

      Guo, Cindy X.; Thompson, Benjamin; Babu, Raiju Jacob; Black, Joanna M.; Bobier, William; Lam, Carly S.Y.; Dai, Shaun; Gao, Tina Y.; Hess, Robert F.; Jenkins, Michelle; Jiang, Yannan; Kowal, Lionel; Parag, Varsha; South, Jayshree; Staffieri, Sandra Elfride; Walker, Natalie; Wadham, Angela (BioMed Central, 2016-10-18)
      Amblyopia is a common neurodevelopmental disorder of vision that is characterised by visual impairment in one eye and compromised binocular visual function. Existing evidence-based treatments for children include patching ...
    • Can current models of accommodation and vergence predict accommodative behavior in myopic children? 

      Sreenivasan, Vidhyapriya; Irving, Elizabeth; Bobier, William (Elsevier, 2014-08)
      Investigations into the progression of myopia in children have long considered the role of accommodation as a cause and solution. Myopic children show high levels of accommodative adaptation, coupled with accommodative lag ...
    • Comparison of super-resolution algorithms applied to retinal images 

      Thapa, Damber; Raahemifar, Kaamran; Bobier, William; Lakshminarayanan, Vasudevan (Society of Photo Optical Instrumentation Engineers, 2014-05-01)
      A critical challenge in biomedical imaging is to optimally balance the trade-off among image resolution, signal-to-noise ratio, and acquisition time. Acquiring a high-resolution image is possible; however, it is either ...
    • The correction of static and dynamic aniseikonia with spectacles and contact lenses 

      McNeill, Suzanne; Bobier, William (Wiley, 2017-02-16)
      We describe a case of where significant anisometropic astigmatism was accompanied with considerable asthenopic symptoms. Symptoms were not alleviated by the prescribing of a partial spectacle correction. Subsequent treatment ...
    • Effect of heterophoria type and myopia on accommodative and vergence responses during sustained near activity in children 

      Sreenivasan, Vidhyapriya; Irving, Elizabeth; Bobier, William (Elsevier, 2012-03-15)
      The influence of phoria-type and myopia on changes to vergence and accommodation during prolonged near-task was examined in 53 children. Participants were classified into phoria and refractive categories based on near ...
    • Effect of near adds on the variability of accommodative response in myopic children 

      Sreenivasan, Vidhyapriya; Irving, Elizabeth; Bobier, William (Wiley, 2011-03)
      Purpose: Higher variability of accommodative response (VAR) has been reported in myopes and speculated to be a possible risk factor for the progression of myopia. We investigated whether near adds of +2D and −2D were capable ...
    • The Regional Extent of Suppression: Strabismics Versus Nonstrabismics 

      Babu, Raiju Jacob; Clavagnier, Simon R.; Bobier, William; Thompson, Benjamin; Hess, Robert F. (Association of Research in Vision and Ophthalmology, 2013-10)
      Purpose.: Evidence is accumulating that suppression may be the cause of amblyopia rather than a secondary consequence of mismatched retinal images. For example, treatment interventions that target suppression may lead to ...
    • Time Course of Dichoptic Masking in Normals and Suppression in Amblyopes 

      Zhou, Jiawei; McNeill, Suzanne; Babu, Raiju Jacob; Baker, Daniel H.; Bobier, William; Hess, Robert F. (Association of Research in Vision and Ophthalmology, 2014-07)
      Purpose.: To better understand the relationship between dichoptic masking in normal vision and suppression in amblyopia we address three questions: First, what is the time course of dichoptic masking in normals and amblyopes? ...
    • 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 ...
