Types of Acquired Color-Vision Defects

Archives of Ophthalmology, 1957
Physical light stimuli, if absorbed by the photosensitive substance or substances in the cones, generate impulses in the photoreceptors. These impulses pass through the centripetal bipolar cells and are transmitted to the ganglion cells, along whose axis cylinders they are finally conveyed to the brain. It is possible that pathological changes in this

COLOR VISION DEFECTS AFTER CENTRAL SEROUS CHORIORETINOPATHY

Retina, 2000
To reexamine patients diagnosed with central serous chorioretinopathy (CSC) during the 10-year period from 1987 to 1996 to identify remaining color vision defects in the eyes with normal visual acuity (VA).Thirty-nine patients were found with normal VA of 20/20 (logMAR 0) or better 8 to 166 months (mean +/- SD, 58.8 +/- 41.2) after active CSC.

Color Vision Defects in Alcoholism–II

British Journal of Addiction to Alcohol & Other Drugs, 1971
SummaryRecent data from Santiago, Chile, in which alcoholics and their female relatives showed higher incidences of overall color blindness and of blue‐yellow color blindness than was seen in controls has been interpreted to support a genetic association between alcoholism and color blindness.In this study, Farnsworth‐Munsell 100‐Hue Color Vision Tests

Acquired Color Vision Defects in Retrobulbar Neuritis

American Journal of Ophthalmology, 1978
We used the Farnsworth-Munsell 100 Hue Test to study the incidence of acquired color vision defects in 16 patients with unilateral and and seven patients with bilateral retrobulbar optic neuritis whose visual acuity had recovered to 6/12 (20/40) or better. We recorded the visual-evoked response to a pattern stimulus on the same day.

Acquired Color Vision Defects

1972
Acquired defects of color vision are common. Their frequency, however, is not generally appreciated. Like all functions of the eye, color vision is influenced by many diseases, congenital abnormalities and even physiological processes such as aging.

Color Vision Defects in Sickle Cell Anemia

Archives of Ophthalmology, 1987
The Farnsworth-Munsell 100-hue test was used to compare color vision in patients with sickle cell anemia, 20/20 visual acuity, and mild to severe peripheral retinopathy, but without posterior retinal vessel involvement, with matched normal controls. Patients with sickle cell anemia had significantly more blue-yellow and mixed color vision defects and ...
