Department of Ophthalmology, Tokyo Medical College, Shinjuku-ku, Japan.

Miscellaneous color vision tests were performed on 66 eyes in 46 acquired blue-yellow deficiency cases, in which the deficiency resembled congenital tritanopia. The confusion loci converged at a point on the short wavelength side of the spectrum in central chorioretinopathy, diabetic retinopathy, branch retinal vein occlusion, retinal pigmentary degeneration, and macular degeneration. However, the confusion loci of glaucoma differed from those of the other 5 diseases of the retina. They crossed the purple boundary, showing a unique tendency among the diseases exhibiting acquired blue-yellow deficiency. In these diseases, except in chorioretinopathy, no correlation was observed between visual acuity, visual field and color confusion.

D008297	Male		Males
D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D003117	Color Vision Defects	Defects of color vision are mainly hereditary traits but can be secondary to acquired or developmental abnormalities in the CONES (RETINA). Severity of hereditary defects of color vision depends on the degree of mutation of the ROD OPSINS genes (on X CHROMOSOME and CHROMOSOME 3) that code the photopigments for red, green and blue.

D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D000368	Aged	A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available.	Elderly
D014792	Visual Acuity	Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.	Acuities, Visual,Acuity, Visual,Visual Acuities
D014794	Visual Fields	The total area or space visible in a person's peripheral vision with the eye looking straightforward.	Field, Visual,Fields, Visual,Visual Field
