Erythropsia and Chromatopsia: Case Study and Brief Review

Academic Article

Abstract

  • © 2020 Taylor & Francis Group, LLC. 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.
