Prevalence and causes of visual impairment among the elderly in Nantong, China

Rapid assessment of avoidable blindness in three counties, Jiangxi Province, China

“…However, our estimates were similar to those obtained from surveys in Shunyi, Beijing, China in 1996 (aged ≥50 years, blindness prevalence=2.8%),10 Nantong, Jiangsu Province (≥60 years, 1.4%),12 Harbin (≥50 years, 1.9%)13 and Chongqing (≥50 years, 1.8%) 8. The estimates from the current RAABs are therefore consistent with previous studies and have been used in planning by the Jiangxi Provincial Health Bureau.…”

Prevalence and causes of visual impairment in a rural North‐east China adult population: a population‐based survey in Bin County, Harbin

“…To facilitate comparison, Table 7 summarizes the prevalence of blindness and its cause reported in different regions of China. The present prevalence of blindness tended to be higher than those reported in Hong Kong (Michon et al 2002), Tibet (Dunzhu et al 2003), Taiwan (Hsu et al 2004), Beijing (Xu et al 2006), Handan (Liang et al 2008) or Nantong (Li et al 2008a), although a direct comparison with these results may be difficult because of differences in the age distribution or definitions of visual impairment. Although the two surveys from Tibet and Handan were performed on a rural population, the same as the present, a younger population in Tibet (All) and Handan ( ‡30) surveys may be the reason for the relative high prevalence in the present study.…”
