Myopia: structural and functional correlates
Ocular dimensions are widely recognised as key variants of refractive error. Previously, accurate depiction of eye shape in vivo was largely restricted by limitations in the imaging techniques available. This thesis describes unique applications of the recently introduced 3-dimensional magnetic …

Structural and functional aspects of myopia in young adults. An investigation of nearwork-induced transient myopia and accommodation in relation to refractive stability.
… has investigated nearwork-induced transient myopia and accommodation responses in relation to refractive stability, multichromatic stimuli and orthokeratology. Five individual studies have been carried out. Initially an investigation into the temporal and dioptric aspects of nearwork-induced …

The association of myopia progression with family history of myopia, nearwork, and other risk factors among Singapore schoolchildren: A 2 year follow-up study
Purpose: To investigate the progression rate of myopia and the possible risk factors among Singapore schoolchildren. Methods: A 2-year follow-up study was carried out among 642 myopic (SER at least - 0.5 D) schoolchildren aged 7-9 years at baseline. Results: The 2-year cumulative progression rate …

Myopia management leadership and modern orthokeratology self-learning in troubleshooting
Nguyen, Liberty Hai Ho Advanced myopia is rising, with 2.56 billion myopic-affected people worldwide (World Health Organization, 2020). Myopia Management Leadership & Self-learning in Orthokeratology is an instructional design textbook focusing on the Ortho-K learners' perspective in …

Digital Darwinism: Temporal Myopia and the Transformation of Institutional Logics
… such costly failure rates is primarily temporal myopia. The author observed such a dynamic as a practitioner first-hand, and this was supported through the literature, where it was cited as pervasive in established organisations.<br/><br/>The author contends that such practitioner-based myopia is …

Assessing Behavioral Factors in Myopia: Development of a Visual Activity Survey
… To conduct a systematic review on near work and myopia and to develop and provide scoring guidelines for the University of Houston Near Work, Environment, Activity, and Refractive Error (UH NEAR) Survey, a comprehensive visual activity survey to aid researchers and clinicians in identifying and …

Peripheral Refractive Error and its Association with Myopia Development and Progression. An examination of the role that peripheral retinal defocus may play in the origin and progression of myopia
Purpose: Currently there are attempts to slow myopia progression by manipulating peripheral refractive error. This study proposed to establish the distribution of peripheral refractive errors in hyperopic, emmetropic and myopic children and to test the hypothesis that relative peripheral hyperopia …

Prevalence and risk factors of myopia among Grade 8 learners in Vhembe District
Myopia is not a simple refractive error but an eyesight-threatening disorder. The disorder has a great impact on public health and the socio-economic well-being of people, particularly children. The aim of this study was to investigate the prevalence of myopia and the risk factors associated with …

Influence of ocular monochromatic aberrations in the development and/or progression of myopia
Aim: To determine an association if any, between ‘on’ and ‘off-axis’ ocular aberrations and a myopic change in refractive error using the data obtained longitudinally. Methods: On and off-axis aberrations of cyclopleged eyes (5 mm pupil diameter) of 646 children were measured during 2004-2005 (age, …

A Convenient Myopia: SEEK, Shaughnessy, and the Rise of High-Stakes Testing at CUNY
<p>A great struggle for racial justice was fought at City College and CUNY from 1964 to 1978. In this archival history, supplemented with thirteen oral histories of students and teachers, and grounded in the larger context of racial segregation and exclusion within American public education and …

The Labrador Retriever as a Model of Naturally Occurring Myopia: Genetic and Environmental Contributions
… dog as an animal model of naturally occurring myopia by identifying genetic and environmental factors which are associated with myopia development in the Labrador Retriever. Methods: A large pedigree of Labrador Retrievers was phenotyped for refractive error. Using statistical (familial …

Physiological responses of human retina and choroid to retinal image defocus: Implications for myopia
… 24 hours after administration of one drop of the myopia-inhibiting agent atropine 0.1%. Signals reflecting outer (direct component, DC) and inner (induced component, IC) retinal activity were analysed in central 6° and peripheral (6° to 24°) retinal zones. Experiment (2): Twenty healthy young …

Lamina Cribrosa and Optic Nerve Head Geometry as a Function of Myopia in Older Normal Eyes
Purpose: Increased age and levels of myopia are potential risk factors for the development of glaucoma. However, their impact on optic nerve head (ONH) structure in normal eyes has not been fully described. We examined whether differences exist in ONH and lamina cribrosa structure with myopia in …

Refractive error, ocular biometry and oculomotor function: The prevalence of myopia and its potential risk factors in the Middle East, with an investigation of dynamic accommodation responses and axial length fluctuations in young myopic adults.
… in young myopic adults. The prevalence of myopia in 3000 Middle Eastern adults (age range 17-40 years) was similar to previously reported levels of myopia in the West. Myopia was associated with a higher level of education, occupations with a high nearwork demand and positive family history …

The Governance of Long-Term Investing in Knowledge Creation - Novel Control Mechanisms for Reducing Managerial Myopia and Increasing Growth in Organizations
… and short-term investments. Such managerial myopia can be induced by excessive reliance on the short-term financial control of management that is based on the comparison of actual income relative to annual or shorter-term targets. Previous research on corporate governance and corporate …

Refractive Outcome in Eyes of Preterm Infants
… factors influencing the occurrence and degree of myopia in premature infants. Patients and METHODS: Refractive errors in 86 premature infants (a gestational age <37 weeks) born between september 1994 and June 2004 were examined. They were subdivided into two groups according to treatment for …
