A 65-year-old woman presented with erythropsia (red-tinged vision) in the right eye from a subfoveal macula dehaemoglobinised intraretinal haemorrhage. Erythropsia is a type of chromatopsia, a condition in which objects appear to be abnormally coloured or tinged with colour. This manuscript provides a brief review of colour vision abnormalities including chromatopsia, and additionally we discuss dyschromatopsia and achromatopsia defined as deficiency and absence of colour vision respectively, both of which may be congenital or acquired. We theorise that the mechanism of the chromatopsia may be selective damage of ganglion cells involved in colour opponency.
一名65岁女性因黄斑中心凹下视网膜内出血血红蛋白化而出现右眼红视（视物呈红色）。红视是色觉异常的一种，即物体看起来颜色异常或带有颜色。本文简要回顾了包括红视在内的色觉异常，此外，我们还讨论了分别定义为色觉缺陷和色觉缺失的色觉障碍和全色盲，这两种情况都可能是先天性或后天性的。我们推测，红视的机制可能是参与颜色拮抗的神经节细胞受到选择性损伤。
