An investigation of the relationship between the structure and function of the myopic eye. Correlating the optical, functional and structural aspects of ametropia in young adult humans.
… firstly the effect of instrument alignment on peripheral refraction measurements and revealed that the corneal vertex was an acceptable alignment position of the Shin-Nippon NVision-K 5001 autorefractor, allowing consistent alignment with other instruments used in this research. Secondly, …

Myopia: structural and functional correlates
… contour values derived from transformation of peripheral refraction data were made with MRI; flatter retinal curvature values were noted when using the MRI technique. A distinctive feature of this work is the evaluation of the relationship between ocular structure and visual function. Multiple …

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
… 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 is a risk factor in the onset …

Following Ocular Changes in United States Optometry Students (FOCUS): Protocol Development and Baseline Data
… Measurements included cycloplegic autorefraction (Grand Seiko), biometry (LenStar), optical coherence tomography (OCT) and OCT angiography (OCTA, Spectralis), and ocular aberrations (COAS HD). Participants were classified into refractive error groups. OCT scans were analyzed for retinal …

Influence of ocular monochromatic aberrations in the development and/or progression of myopia
… [C(4,0)] and a hyperopic shift in relative peripheral refractive error (RPRE), whereas eyes with ‘no change’ had an increase in on-axis C(4,0) and no difference in RPRE. Eyes with Type III and Type IV skiagram at baseline showed the most (61%) and the least (17%) myopic change respectively. …
