Color vision tests were performed on 211 German ophthalmologists during their annual meeting at Essen. The subjects also answered detailed questionnaires about their use of lasers and operating microscopes, and their ocular and general health. It was found that 33% of doctors who use lasers or operating microscopes have decreased color discrimination for colors in a tritan color-confusion axis (greater than 2 standard deviations above normal). There is a relationship between number of patients treated and the degree of threshold elevation. Thirty hours of using the operating microscope produces an increase in tritan threshold equivalent to one panretinal photocoagulation.
在埃森举行的年会上，对211名德国眼科医生进行了色觉测试。这些受试者还回答了关于他们使用激光和手术显微镜的详细问卷，以及他们的眼部和整体健康状况。结果发现，使用激光或手术显微镜的医生中有33%在蓝黄色觉混淆轴上对颜色的辨别能力下降（高于正常水平2个标准差以上）。治疗患者的数量与阈值升高程度之间存在关联。使用手术显微镜30小时会使蓝黄色阈值升高，相当于一次全视网膜光凝。
