Color vision was examined by the Farnsworth 100 hue test in 48 eyes with ocular hypertension (OHT). Thirteen eyes had a general loss of color discrimination and 8 had a blue-yellow axis. Spatial contrast sensitivity was tested in 31 eyes with OHT by the Mentor B-VAT and was reduced in 8 of them. Temporal contrast sensitivity was explored in 40 eyes with OHT by the Flickersyst&m and showed abnormal responses in 11 eyes. According to the lack of specificity of the responses and the overlapping of the results of normal eyes and OHT eyes, those tests are not useful for classifying an individual patient. Such investigations however have the interest to show that macular mediated functions may be impaired early in glaucoma.
采用法恩斯沃思100色觉试验对48只高眼压（OHT）眼进行色觉检查。13只眼存在色觉辨别能力普遍丧失，8只眼存在蓝黄轴异常。采用Mentor B-VAT对31只高眼压眼进行空间对比敏感度测试，其中8只眼的空间对比敏感度降低。采用Flickersyst&m对40只高眼压眼进行时间对比敏感度检测，11只眼显示异常反应。由于这些反应缺乏特异性，且正常眼和高眼压眼的结果存在重叠，这些测试对个体患者的分类并无帮助。然而，此类研究表明青光眼早期黄斑介导的功能可能受损，这一点很有意义。
