Zhao, J. et al. The progression of refractive error in school-age children: Shunyi district, China.
PURPOSE: To assess the progression of refractive error and the incidence of myopia in school-age children in the Shunyi District of Beijing, China.
In addition, several studies have reported on the longitudinal progression of refractive error.
The columns in Table 2 corresponding to "Bg≤BgBlst", "End>EdBlst", "PhsBlst" and "Bg&Phs" show the progression of the error.
The mean progression of refractive error in the myopic direction was significantly lower in the intervention group than in the control group (-0.10 ± 0.65 D/year vs. -0.27 ± 0.52 D/year, P = 0.005).
Thus, the primary aim of the study was to investigate the progression of the refractive error, and ocular aberrations, over a period of nine months.
Both the SRRG and OK groups slowed progression of the refractive error by about 43% and 67%, respectively, and they slowed the ocular growth by about 27%and38%8%, respectively.
It will provide estimates on the incidence of blindness and visual impairment, the incidence and progression of: cataract, refractive error, glaucoma, ARMD and DR as well other retinal conditions.
The child's age, baseline refractive error, any evidence of recent progression, and refractive error of parents may help to predict the likelihood of progression.
A steady (non-significant) progression of impairment on WCST perseverative errors (PE) was demonstrated from basic symptom at-risk (BS), ultra high-risk (UHR) and first-episode (FE) groups (BS: z=−0.74; UHR: z=−0.88; FE: z=−0.97).
