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 test the hypothesis that relative peripheral hyperopia is a risk factor in the onset and progression of myopia. Methods: Refraction was measured under non-cycloplegic conditions, at 0°, 10° (superior, inferior, temporal and nasal retina) and 30° (temporal and nasal retina), at distance and …

Refractive Outcome in Eyes of Preterm Infants
… significant differences in the prevalence of hyperopia under the age of 4, and the degree of hyperopia was higher in premature infants born without threashold ROP than the others. The prevalence and the degree of astigmatism were similar among three groups. There were no significant …

School vision screening programmes: the benefits of including measurements of refractive error.
… to the role of detecting refractive error namely hyperopia thus far. The purpose of this thesis was to determine the benefits of including a refractive error assessment at vision screening. The value of including a refraction was investigated by retrospectively analysing those children who had …

Heme Oxygenase-2 as a novel target to treat inflammation and chronic neuropathic pain associated with corneal injury and surgery
… the shape of the cornea correlated with myopia, hyperopia and astigmatism. More than 12 million patients have undergone refractive surgery since it was approved (see http://www. laser-eye-surgery statistics.com/). Laser-assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) …

Clinician measurement of spectacle prescription changes and patient tolerance to them
Purpose. To investigate the subjective refraction techniques of UK optometrists and their influence on patient-reported problems with new spectacles. Methods. First, an investigation from optical practices’ perspective, with a study investigating the frequency and causes of patient complaints. …

The Effects of Low Intensity Ambient Lighting on Refractive Development in Rhesus Monkeys (Macacca mulatta)
PURPOSE: Elevated ambient lighting levels protected animals from certain forms of experimental myopia, suggesting that alterations in ambient lighting levels influence refractive development. The purpose of the studies reported in this dissertation was to evaluate the extent to which low ambient …
