deuteranopia [doo″ter-ah-no´pe-ah] defective color vision, with confusion of greens and reds, and retention of the sensory mechanism for only the hues of blue and yellow. adj., adj deuteranop´ic.deu·ter·an·o·pi·a (dū'tĕr-ă-nō'pē-ă), A congenital abnormality of the retina in which there are two rather than three retinal cone pigments (dichromatism) and complete insensitivity to middle wavelengths (green). [G. deuteros, second, + anopia] deuteranopia (do͞o′tər-ə-nō′pē-ə, dyo͞o′-)n. A form of colorblindness characterized by insensitivity to green.

See Color blindness. deu·ter·an·o·pi·a , deuteranopsia (dū'tĕr-ă-nō'pē-ă, -opsē-ă) A congenital abnormality of the retina in which there are two rather than three retinal cone pigments (dichromatism) and complete insensitivity to middle wavelengths (green). [G. deuteros, second, + anopia]deuteranopia A form of colour blindness (colour perception defect) causing a tendency to confuse blues and greens, and greens and reds and with a reduced sensitivity to green.deuteranopiaType of dichromatism in which red and green are confused, although their relative spectral luminosities are practically the same as in normals. In the spectrum, the deuteranope only sees two primary colours, the long wavelength portion of the spectrum (yellow, orange or red) appears yellowish and the short wavelength portion (blue or violet) appears bluish. There is, in between, a neutral point which appears whitish or colourless, at about 498 nm. It occurs in slightly over 1% of the male population and only rarely in females. Syn. green blindness (although this term is incorrect as green lights appear to a deuteranope as bright as to a normal observer). See defective colour vision; dichro-matism.deuteranopia
