方法：纳入8 316名常住人口，开展盲与低视力流行病学调查。先将T2DM患者纳为观察组、将其它受检对象纳为对照组，对比两组盲与低视力患病率及发病原因； 随后仅分析观察组数据。

结果：观察组盲与低视力出现率明显更高； 白内障及视网膜病变出现率明显更高。随年龄增加，观察组盲与低视力出现率明显提升； 女性致低视力率明显更高； 初中及以上学历者盲与低视力出现率明显更高。上述分析均有统计学意义(P<0.05)。

结论：我区T2DM患者盲与低视力患病率明显高于未合并T2DM者； T2DM患者盲与低视力出现与年龄、性别、学历有一定关系。

METHODS: A total of 8 316 permanent residents, to carry out epidemiological survey of blindness and low vision. Carolina First T2DM patients were in the observation group, the other subjects admitted to the control group. Prevalence and etiology of blind and low vision were compared. Then the data only in the observation group were analyzed.

RESULTS:The rate of blindness and low vision appeared significantly higher, cataracts and retinopathy appeared significantly higher. With the increases of age, prevalence of blindness and low vision appeared significantly increased in the observation group. The rate of low vision was higher in women. Blind and low vision appeared significantly higher in junior high school educations. The above analysis was statistically significant(P<0.05).

CONCLUSION: The prevalence of blindness and low vision of T2DM patients in our region were significantly higher than the unconsolidated. Blind and low vision in T2DM patients has a certain relationship with age, sex, education.
