The prevalence of refractive error and visual impairment caused by uncorrected refractive error in ChinaNg, Siu-chun, Danny., 吳兆駿. January 2010 (has links)
Purpose: WHO reports 46% of world vision impairment from refractive error (RE)
among children occurs in China. We estimated RE prevalence and associated vision
impairment (VI) among Chinese children and adults.
Methods: Data from population-based studies were stratified by gender in age intervals
of 3 years (ages 3-17 y) or 10 years (ages >= 30 y): counts of persons with myopia
(worse eye spherical equivalent <= -1.0D, <= -2.0D, <= -6.0D) and prevalence of low
vision (< 6/12 in the better-seeing eye for children and < 6/18 for adults) and blindness
(<=6/60) attributable to RE. Figures for VI included persons with habitual vision below
the cutoff improving to above the cutoff with refraction, and those with myopic
retinopathy. Estimates for ages 18-29 y were obtained from regression models derived
from the pooled estimates. Prevalence of myopia and VI attributable to RE in each
age/gender category was calculated by applying modeled rates to 2000 China census
figures and projections for 2020. Association with VI attributable to RE was tested for:
gender, urban versus rural residence, and residence in provinces with per capita GDP in
the upper versus lower 50% for China.
Results: Data were obtained from 5 cohorts for children and 14 for adults. There were
291 million and 21.4 million persons with myopia <= -1.0D and <= -6.0D respectively in
2000, expected to rise to 306 million and 36.9 million by 2020. Of these, 18.4 million
were blind and 116 million had low vision in 2000, with figures of 25.3 million and 123
million in 2020. Children accounted for the following proportion of RE disease burden in
China in 2000: myopia <= -1.0D: 19.0%; RE-associated low vision: 56.1%; blindness:
14.1%. Refractive error was responsible for 82.3% of blindness and 90.5% of low vision
among children, and 11.6% and 64.4% of blindness and low vision among adults. Urban
residence (OR 1.85, P = 0.004) and higher GDP (OR 10.6, P < 0.001) were associated
with refractive blindness among children. For adults, lower GDP was associated with
refractive blindness (OR 1.47, P = 0.01). Gender was un-associated with refractive
blindness among children or adults.
Conclusions: Both children and adults suffer a heavy burden of VI associated with RE in
China. Income may affect risk for such VI differently among children and adults. / published_or_final_version / Public Health / Master / Master of Public Health

Relationship between reading loss and visual disability for one hundred fifth and sixth grade pupils in Modesto, CaliforniaIsaac, Lincoln Emil 01 January 1959 (has links)
The purpose of this study was to discover if there is a relationship between reading loss and visual disability and to assay the reading losso that is characteristic for individuals with a visual disability. The intent was not to diagnose that all reading loss can be attributed to a visual disability or define visual defects, for the latter requires a careful examination by an eye specialist, but rather to determine if the child’s reading may be affected by a blurred visual image or by eye-muscle fatigue.
