Phase 1 investigates additional factors that may predict the onset of juvenile myopia (accommodative function, peripheral refractive error, intraocular pressure, and school achievement). http://supercgis.com/refractive-error/refractive-error-and-ethnicity-in-children.html
The majority of the children were orthophoric, 58%. Refractive error was the main cause of visual impairment in children aged between 7 and 15 years in rural India. The major difference between this RESC survey and the others, 6 7 8 9 with which it can be compared, is that the sample was drawn from children between 7 and Examinations were generally performed during standard clinic hours and 6 days a week.

Clustering effects were taken into account in the calculation of confidence intervals for prevalence estimates and in regression analyses. Condition Myopia Study Type: Observational Resource links provided by NLM: MedlinePlus related topics: RefractiveErrors U.S. In multiple logistic regression, astigmatism in the right eye was associated with female gender with both retinoscopy and autorefraction (P = 0.006 and P = 0.028, respectively) and with older age Children were transported to the examination site on the scheduled date.

There was a benefit of spectacles in 70% of those who had visual acuity of 20/40 or worse in the better eye at baseline examination. original site For general information, see Learn About Clinical Studies. Collaborative Longitudinal Evaluation Of Ethnicity And Refractive Error Cycloplegic autorefraction was performed using a handheld autorefractor (Retinomax K-Plus; Nikon Corp., Tokyo, Japan), with calibration at the beginning of each day. Data points represent a 1-D interval (for example, those associated with +1 on the x-axis represent more than +0.50 D to +1.50 D or less).

The mean differences of 0.13 and 0.11 D for right and left eyes, respectively, are clinically insignificant. We compared accommodation insufficiency and factors including age, refractive errors and NPC.
Sample size was based on that estimated for the earlier studies, 5 with a 20% increase to accommodate lower examination response rates and larger cluster design effects. Field Operations Fieldwork was In spite of the high prevalence of myopia in Asians , there were only three low myopia patients.
