The therapeutic efficiency of the Ginkgo biloba extract was estimated in a double-blind trial, during a 6 months period, in 29 diabetic subjects with an early diabetic retinopathy evidenced by angiography, and associated with a blue-yellow dyschromatopsia. The functional criterion was the color vision evolution, studied by the Desaturated Panel D-15 and the 100-Hue Farnsworth test at the beginning of the trial and 6 months later. An improvement tendency was evidenced in subjects treated by Ginkgo biloba extract, and an aggravation in subjects with placebo, this improvement being statistically significative with the Desaturated Panel D-15 among subjects without retinal ischemia. These clinical results on visual function corroborate the pharmacological actions of Ginkgo biloba extract on diabetic retina.
在一项双盲试验中，对29名患有早期糖尿病视网膜病变（经血管造影证实）且伴有蓝黄色色盲的糖尿病患者进行了为期6个月的研究，以评估银杏叶提取物的治疗效果。功能标准是色觉变化，在试验开始时和6个月后通过不饱和D-15色盘和100色调法恩斯沃思测试进行研究。服用银杏叶提取物的受试者有改善趋势，服用安慰剂的受试者病情加重，在没有视网膜缺血的受试者中，使用不饱和D-15色盘时这种改善具有统计学意义。这些关于视觉功能的临床结果证实了银杏叶提取物对糖尿病视网膜的药理作用。
