AB  - PURPOSE: To evaluate the prevalence and causes of visual impairment in a group of 
      community people with type 2 diabetes mellitus (T2DM) in Northeast China. 
      METHODS: Population-based cross-sectional survey. Patients diagnosed with T2DM 
      residing in 15 communities in Fushun, Northeast China, were enrolled between July 
      2012 and May 2013. All participants underwent an extensive and standardized eye 
      examination (visual acuity testing, slit-lamp, and fundus examination). Low 
      vision was defined as presenting VA of better-seeing eye <20/60 and >/=20/400, and 
      blindness was defined as VA <20/400, according to the World Health Organization 
      (WHO) definitions. The primary causes of blindness and low vision were assessed 
      by senior ophthalmologists. RESULTS: Visual acuity measurements were available 
      for 1998 (89.8%) of 2224 subjects in the study. The prevalence of bilateral 
      blindness and low vision defined was 0.90% and 10.81%. Uncorrected refractive 
      error was the first leading cause of low vision (75.0%) and blindness (38.9%). 
      After correcting the refractive error, the first leading cause of low vision was 
      cataract (44.4%), followed by diabetic retinopathy (29.6%) and myopic maculopathy 
      (18.5%), while the first leading cause of blindness was proliferative DR (45.4%), 
      followed by cataract (36.4%) and myopic maculopathy (18.2%). CONCLUSIONS: This 
      study suggested a high prevalence of low vision and blindness in this study 
      cohort. Uncorrected refractive error and cataract remain the leading cause of 
      visual impairment, but the major challenge is the early diagnosis and 
      intervention of diabetic retinopathy to reduce diabetes-related blindness.
