Differences Between Protocol And Review: 2013 update: •We decided to remove the RCT filter from the electronic searches in order to identify as many potentially relevant studies as possible. We also specified that reading speed had to be measured at ordinary print size because this is the outcome most relevant to patients in terms of performance using a specific low-vision aid. We also specified that MNREAD definitions of maximum reading speed and reading acuity were adopted in our review and the consequences of this choice are discussed in the revised version. •We used raw reading acuity (words per minute) rather than its log transformation, as done in the original version using individual values, because results are more interpretable on this scale, despite mild skewness. •We also adapted the 'Risk of bias' assessment following new guidance. We reconsidered the scoring of 'within-subject' or crossover-like studies, leading to adapted criteria to score the quality of randomisation and allocation concealment.

“…Although NEDs have been used as electronic vision enhancement displays for the visually impaired, the number of studies on the use of NEDs for reading tasks or as accessories for enhancement for small-sized displays is limited [62,63,55,36]. Sheedy and Bergstom [55] found a small increase in task performance speed when tasks were performed on near-eye displays compared to flat panel displays and hard copies.…”

Reading e-books on a near-to-eye display: Comparison between a small-sized multimedia display and a hard copy

Eighty-seven participants read an e-book either from a near-to-eye display, a small-size display or a hard copy. Eyestrain, visually induced motion sickness, changes in visual functioning, user experience, and the essential optical parameters of the reading equipment were evaluated. The results indicate that reading from a hard copy was the most comfortable experience. All near-to-eye displays induced eyestrain and sickness symptoms, but the magnitude of these symptoms varied according to the device. The adverse symptoms were related to problems with the display optics and design, text layout, headset fit, use context, and individual differences. Keywords: near-to-eye display, small-sized display, eyestrain, discomfort, readingReading text is a complex and highly automated process during which readers extract visual information from the page and comprehend the text's meaning [1,2]. Depending on a reader's motivations, the text type, the media format, and the context, the process of reading varies between and within readers [3]. For example, reading a printed book may be an engrossing, effortless, and relaxing experience that lasts for hours, whereas reading the same text in electronic format may be a consciously demanding process because of poor text legibility and technology-related limitations [3,4,5,2,74,75]. As a result, the reader may experience frustration, fatigue, eyestrain or visual discomfort, which could affect reading-related practices [6,7].

cien. tecnol. salud. vis. ocul. / vol. 10, no. 2 / julio-diciembre del 2012 / pp. 93-102 / issn: 1692-8415 RESUMEN El macroadenoma hipofisiario es un tumor de diámetro superior a 10 mm ubicado en la hipófisis, con una prevalencia del 0,20 % en población viva no seleccionada. Las manifestaciones clínicas incluyen alteraciones visuales tales como defectos en el campo visual (CV) debidos al desplazamiento del quiasma óptico de su posición inicial. La prevalencia de los defectos del CV varía del 32 % al 96 % y generalmente se encuentra hemianopsia bitemporal. Estos pacientes raramente se manejan de manera itegral y son considerados como pacientes con baja visión según la OMS. De aquí la importancia del conocimiento del manejo optpmétrico integral en estos casos Manejo optométrico de baja visión asociada a macroadenoma hipofisiarioOptometric management of low vision associated to pituitary macroadenoma Diana Gutiérrez Melgarejo* *Optómetra, MSc. Ciencias de la Visión, Universidad de La Salle.Palabras clave: adenoma hipofisiario, hemianopsia bitemporal, baja visión. ABSTRACTPituitary adenoma is a tumor with a diameter greater than 10 mm located in the pituitary gland, with a prevalence of 0.20 % in unselected living population. Clinical manifestations include visual disturbances such as visual field defects due to displacement of the optic chiasm from its normal position. The prevalence of visual field defects varies from 32% to 96%, and bitemporal hemianopsia is typically found. These lesions rarely have a full recovery, and so these patients are categorized as low vision patients according to the World Health Organization; hence the importance of knowing what the optometrist intervention and management are in such cases.
