To estimate global and regional trends from 1990 to 2010 of the prevalence and number of persons visually impaired specifically by diabetic retinopathy (DR), as a complication of the precipitous trends in global diabetes, is fundamental for health planning purposes.
The meta-analysis of published population studies from 1990 to 2012 for the Global Burden of Disease Study 2010 (GBD) yielded estimated global regional trends in DR among other causes of moderate and severe vision impairment (MSVI; presenting visual acuity <6/18, ≥3/60) and blindness (presenting visual acuity <3/60).
Globally in 2010, out of overall 32.4 million blind and 191 million visually impaired people, 0.8 million were blind and 3.7 million were visually impaired because of DR, with an alarming increase of 27% and 64%, respectively, spanning the two decades from 1990 to 2010. DR accounted for 2.6% of all blindness in 2010 and 1.9% of all MSVI worldwide, increasing from 2.1% and 1.3%, respectively, in 1990. These figures were lower in regions with younger populations (<2% in East and Southeast Asia and Oceania) than in high-income regions (North America, Western Europe, and Australasia) with relatively aging populations (>4%).
The number of persons with visual impairment due to DR worldwide is rising and represents an increasing proportion of all blindness/MSVI causes. Age-standardized prevalence of DR-related blindness/MSVI was higher in sub-Saharan Africa and South Asia. One out of 39 blind people had blindness due to DR, and 1 out of 52 visually impaired people had visual impairment due to DR.
由于糖尿病的急剧流行，糖尿病性视网膜病变（DR）作为其主要并发症，导致全球视力受损患者数量增加。评估 1990 年至 2010 年全球及各区域因 DR 导致的视力受损患病率和人数的变化趋势，对于卫生规划具有重要意义。
对 2010 年全球疾病负担研究（GBD）中发表于 1990 年至 2012 年的人群研究进行 meta 分析，以评估其他原因导致的中度和重度视力损伤（MSVI；最佳矫正视力<6/18，≥3/60）和失明（最佳矫正视力<3/60）中 DR 的全球和区域趋势。
2010 年，全球有 3240 万盲人及 1.91 亿视力受损者，其中 0.8 万盲人及 370 万视力受损者是由 DR 导致的，在这二十年中，DR 的患病率分别增加了 27%和 64%。2010 年，DR 占所有失明的 2.6%，占全球所有 MSVI 的 1.9%，相较于 1990 年，分别升高了 2.1%和 1.3%。在人口较年轻的地区（东亚和东南亚及大洋洲<2%），DR 导致的失明人数比例低于人口老龄化地区（北美、西欧和澳大拉西亚>4%）。
全球范围内，因 DR 导致视力受损的人数正在上升，且在所有失明/MSVI 病因中的占比逐渐增加。DR 相关性失明/MSVI 的年龄标准化患病率在撒哈拉以南非洲和南亚更高。每 39 名盲人中有 1 人因 DR 而失明，每 52 名视力受损者中有 1 人因 DR 而视力受损。
