Spatial contrast sensitivity of 19 diabetics with different degrees of visual impairment was studied. It was found that contrast sensitivity at intermediate and low spatial frequencies may decrease without corresponding loss of visual acuity. In advanced cases of diabetes the opposite may be true: contrast sensitivity was better than expected on the basis of visual acuity. Thus both visual acuity and contrast sensitivity measurements are useful in the evaluation of the nature of visual impairment due to diabetic eye disease.
对19名不同程度视力损害的糖尿病患者的空间对比敏感度进行了研究。发现中低空间频率下的对比敏感度可能会下降，而视力并无相应损失。在糖尿病晚期病例中情况可能相反：对比敏感度优于基于视力预期的情况。因此，视力和对比敏感度测量在评估糖尿病眼病所致视力损害的性质方面均有用处。
