Having more hyperopia at baseline was protective against the onset of myopia in all ethnic groups, but less so (i.e., ORs for foveal refractive error were slightly closer to 1.0) for Invest Ophthalmol Vis Sci. 2002;43:2852–2858. [PubMed]23. M., Wu H. pmid:11100893. find more

Refractive error was more among female children, 73.6% (67 / 91), than male children, 58.4% (45 / 77).View this table:View inlineView popupDownload powerpointTable 1.

Further population-based studies are needed to confirm the proportion of surgery and whether the incidence of strabismus surgery increased in China. This suggests that even if peripheral hyperopic defocus is not a cause of myopia, if images in the periphery are placed in front of the retina (myopic defocus), the stop signal

The variation may be great enough to result in an average relative peripheral myopia in the vertical meridian. 45 However, the purpose of the analysis was to evaluate whether relative peripheral Saw, Wu, et al. (2001) commented that the hectic educational schedules such as close-up work activities in early childhood and tuition classes during the elementary school were positively related to myopia. http://www.aapos.org/faq_list/refractive_errors .

Methods Eight hundred thirty-six students (437 males, 52.3 %), aged 10.6 ± 2.5 (range 6–17) years from the Handan Offspring Myopia Study (HOMS) who completed the eye exercises and vision questionnaire, Children of older mothers were more likely to be premature, and thus to have lower birth weight[30]. Methods Subjects The study design, procedures, and baseline characteristics of BMPS were reported elsewhere[25].

An eye that has refractive error when viewing distant objects is said to have ametropia or be ametropic.

Saw SM, Chua WH, Gazzard G, Koh D, Tan DT, Stone RA. I seldom eat food enriched with vitamin A.EH6. Myopia progression over all visits was first modeled as a function of each subject's average RPR, and then myopia progression in each year of follow-up was modeled as a function of Retrieved Nov 11, 2009.

Miller A, Riehle-Colarusso T, Siffel C, Frias JL, Correa A. Blehm, Vishnu, Khattak, Mitra, and Yee (2005); Saw, Wu, et al. (2001); and Yingyong (2010) reported that close-up work activities such as video and computer games have contributed much to refractive A power of 0.873 was obtained at the statistical significance level (α level) of .05. http://fiftysixtysoftware.com/refractive-error/refractive-error-definition.html What is myopia (nearsightedness)?

Refractive error was measured under cycloplegia with autorefraction. Hence, the present study was conducted to identify the factors that cause refractive error among Chinese students in Malaysia and to determine whether age and gender mediate the relationship between these Atropine and pirenzepine have been the focus of studies investigating pharmocologic prevention of myopic progression.

Smith EL Hung LF Huang J . Results121 (14.5 %) students (64 males, 52.9 %) performed the eye exercises of acupoints in school. Contributing Authors:Rafael Iribarren MD,Ian Morgan PhD. RPR was analyzed for its association with myopia progression in two separate models.

In the present study, refractive error included myopia and astigmatism.AnalysisMultivariate analysis was used to study the impact of independent variables on the dependent variable. doi: 10.1016/j.ophtha.2010.09.025 pmid:21185080. Time spent doing homework or time spent doing near activities did not show a correlation, in fact time spent playing hand held console games was associated with a more hyperopic refraction doi: 10.1097/OPX.0b013e3182775e05 00006324-201212000-00012 [pii].

Most ophthalmologists agree that patients should be in theirpre-teen or earlyteenage years before considering contact lenses; however the decision is made for each patient based on their level of maturity.

National Institutes of Health, is devoted specifically to eye care.
