1. In order to find the ability to read Braille teach in diabetes with vision-impaired, the following studies have performed : (1) effect of reading Braille on study on sensibility and contact force in Diabetic, (2) effect of reading Braille on sensibility and bloodstream in diabetic, (3) study on the elasticity of the finger pulp in diabetic, (4) development of sensibility evaluation program for diabetic neuropathy.2. Diabetics with vision-impaired have sensory disturbances and their sensory receptors and nerve fibers have high fatigability to repetitive stimulation. Also their bloodstream and elasticity of the finger pulp is decreasing. As reading Braille, diabetics have the tendency to their finger press harder on Braille. These cause decreasing bloodstream and sensibility and then, cause a chain reaction. Finally they have difficulty to read Braille.3. Proposals for education of Braille reading in diabetics with vision-impaired : (1) to read Braille, use most sensitive finger, (2) Reduce force and sustain adequate contact force with Braille, (3) not to maintain reading Braille more than 8 mints and take a rest, (4) certain exercises for making fist and relax help bloodstream, (5) before teaching them, their sensibility of finger pulp must be evaluate.

1.为了发现糖尿病视力受损患者阅读盲文教学的能力，进行了以下研究：（1）阅读盲文对糖尿病患者感觉和接触力研究的影响;（2）阅读盲文对糖尿病患者感觉和血流的影响;（3）糖尿病患者指腹弹性的研究;（4）糖尿病神经病变感觉评估程序的开发.糖尿病视力障碍患者存在感觉障碍，其感觉感受器和神经纤维对重复刺激具有高疲劳性。而且他们的血流和指腹的弹性正在下降。在阅读盲文时，糖尿病患者有手指在盲文上用力按压的倾向。这些会导致血流和敏感性下降，然后引起连锁反应。最后，他们有困难阅读盲文。糖尿病视力障碍患者盲文阅读教育建议：（1）阅读盲文，使用最敏感的手指;（2）减少力量，并保持与盲文的足够接触力;（3）保持阅读盲文不超过8分钟，并休息;（4）一定的握拳和放松练习有助于血液循环;（5）在教他们之前，应评价其指腹敏感性。
