Colour vision of 60 diabetic patients (60 eyes) was studied after photocoagulation treatment in 1986-87. For the follow-up study 5 years later in 1991-92, 32 of the patients were available. The ages of the patients in the follow-up study varied from 28 to 64 years, the duration of diabetes from 19 to 35 years, the amount of laser spots from 200 to 3174, and the visual acuity from 0.4 to 1.0. As colour vision tests, the Standard Pseudo-isochromatic Plates part 2, Lanthony Tritan Album, Farnsworth Panel D 15, and box III of the Farnsworth-Munsell 100 hue test were used. Of the 32 eyes, 22 (68.8%) had the same results in the colour vision tests, 4 (12.5%) had better results, and 6 (18.8%) had worse results than 5 years earlier. Between Group 1 (colour vision the same or better than 5 years earlier, 26 eyes) and Group 2 (colour vision worse than earlier, 6 eyes) there was a significant difference in the age and in the level of the visual acuity of the patients. The changes in the lens, fundus or visual acuity during 5 years did not seem to have an effect in colour vision.
1986 - 1987年对60例糖尿病患者（60只眼）进行了光凝治疗后的色觉研究。在1991 - 1992年进行5年后的随访研究时，有32例患者可供研究。随访研究中的患者年龄在28至64岁之间，糖尿病病程在19至35年之间，激光光斑数量在200至3174个之间，视力在0.4至1.0之间。作为色觉测试，使用了标准假同色图第2部分、兰托尼三色视标、法恩斯沃思D - 15色盘以及法恩斯沃思 - 芒塞尔100色调测试的III号盒。在这32只眼中，22只（68.8%）色觉测试结果与5年前相同，4只（12.5%）结果更好，6只（18.8%）结果比5年前更差。在第1组（色觉与5年前相同或更好，26只眼）和第2组（色觉比之前更差，6只眼）之间，患者年龄和视力水平存在显著差异。5年间晶状体、眼底或视力的变化似乎对色觉没有影响。
