consumption and its entry via facilitated diffusion [5] . An increase in both the glucose gradient (as in hyperglycemia) and/or its diffusion facility can increase its aqueous concentration. Almost all the patients of the abovementioned paper were treated with insulin. As we know, insulin is a hormone which facilitates glucose uptake and consumption in the body. Although it has not been proved ...

purpose : to present conductive keratoplasty (ck) as a new procedure to correct residual hyperopia and astigmatism after phacoemulsification surgery and to evaluate its predictability, safety and stability methods : fifteen eyes of 13 patients with preoperative hyperopia +0.75 to +3.00 d and or astigmatism -0.75 to -3.00 d were enrolled into the study and underwent ck treatment. at the 1st and ...

Purpose The aim of the study was a systematic review of refractive errors across the world according to the WHO regions. Methods To extract articles on the prevalence of refractive errors for this meta-analysis, international databases were searched from 1990 to 2016. The results of the retrieved studies were merged using a random effect model and reported as estimated pool prevalence (EPP) w...

BACKGROUND Vision screening addresses the visual impairments that impact on child development. Tests of long-sightedness are not found in most school screening programmes. The evidence linking mild-moderate hyperopia and lack of progress in school is insufficient, although strengthened by recent findings of developmental problems in infants. AIMS To report on the relation between hyperopia an...

PURPOSE To evaluate laser in situ keratomileusis (LASIK) for induced hyperopia after radial keratotomy. METHODS Twenty eyes had LASEK for induced hyperopia after radial keratotomy. All eyes were treated using the Nidek excimer laser (EC-5000) and the Hansatome microkeratome with a 905-mm ring and 180-mm plate. Hyperopic correction was done using a 5.5 to 7.5-mm ablation zone. RESULTS Mean p...

BACKGROUND The PlusOptix photoscreeners (PlusOptix GmbH, Nuremberg, Germany) is used in many vision screening programs. The purpose of the present study was to further explore the accuracy of the PlusOptix A09 photoscreener in children with ametropia (myopia or hyperopia). METHODS A total of 70 eyes (35 children) were prospectively included. Before administration with the cycloplegia treatmen...

Game-theoretic models of network formation typically assume that people create relations so as to maximize their own outcome in the network. Recent experiments on network formation suggest that the assumption of self-interest might be unwarranted and that social preferences, such as altruism and inequality aversion, play a role in the formation of social networks. We developed an experiment to ...

OBJECTIVE To summarize relevant evidence investigating the associations between refractive error and age-related macular degeneration (AMD). DESIGN Systematic review and meta-analysis. METHODS We searched Medline, Web of Science, and Cochrane databases as well as the reference lists of retrieved articles to identify studies that met the inclusion criteria. Extracted data were combined using...
