| 1932 S. Duke-Elder Text-bk. Ophthalm. I. xxv. 975 There may be a relative failure in the appreciation of red or of green, the cases being respectively called partial protanopia (protanomaly or ‘green-sightedness’) and partial deuteranopia (deuteranomaly or ‘red-sightedness’). 1946, etc. [see protanomaly n.]. 1956 Brit. Jrnl. Ophthalm. XL. 463 Weale's subject J. G. was a compound heterozygote for protanomaly and deuteranomaly. 1968 Vision Res. VIII. 469 (heading) A pedigree showing variability in deuteranomaly. 1984 Ophthalmic Res.
