In 14 eyes of 14 patients with diabetic retinopathy the light sensitivity of retinal cotton-wool spots was studied by computerised perimetry, and the visual field data were accurately correlated with the corresponding morphology as seen on fundus photographs and fluorescein angiograms. In 12 of the eyes the examinations were repeated within one year in order to follow changes in retinal light sensitivity during the evolution of the lesions. Retinal cotton-wool spots were in all eyes associated with localised non-arcuate scotomata in the visual field. In four eyes the cotton-wool spots disappeared within three months of the first examination, and in two of these cases the corresponding scotomata disappeared together with the morphological lesions. In eight eyes the cotton-wool spots (and the corresponding scotomata) had not resolved one year after the first examination. The mean blood pressure showed no significant difference between the patients in whom the lesions resolved within three months and the patients in whom the lesions persisted longer.
在14例糖尿病性视网膜病变患者的14只眼中，采用计算机视野计研究了视网膜棉絮斑的光敏感度，并将视野数据与眼底照片和荧光素血管造影所见的相应形态进行了精确关联。其中12只眼在1年内重复进行检查，以跟踪病变发展过程中视网膜光敏感度的变化。所有眼中的视网膜棉絮斑均与视野中的局限性非弓形暗点相关。4只眼中的棉絮斑在首次检查后3个月内消失，其中2例相应的暗点随形态学病变一同消失。8只眼中的棉絮斑（及相应的暗点）在首次检查1年后仍未消退。病变在3个月内消退的患者与病变持续时间较长的患者之间，平均血压无显著差异。
