Color Vision Defects in Non‐Alcoholic Relatives of Alcoholic Patients

Relationship of Color Blindness to Alcoholic Liver Damage

“…[10|. It seems clear that the blue-yellow disturbance found prevalent among alcoholics both in this study and in the previous one by Varela et al [10] is mild and cannot be classified with the specific HRR test plates, but nevertheless il appears to be useful as a genetic marker.…”

“…In order to know whether or not our material is comparable to that employed in previous works, we have summarized in table I the distribution of color vision defects in the total of our sample and tile distribution found by Varela et al [10] among alcoholics and controls. The tests reported in the present work are performed by the same person as those of Varela et al (L. Rivera).…”

“…The cap erro r of the FM test w as com puted according to the F a rn sw o rth M anual. Red-green and blue-yellow zones were delim ited according to previous w ork [10).…”

“…[10] studied a group of 65 alcoholics, 41 non alcoholic relatives of them and 97 non alcoholics controls with the FM 100 test, which enables to explore the whole visible spectrum. The re sults of this study showed that color vision defect in alcoholics was mainly localized in the blue-yellow confusion lines, which correspond to Tritan and the controversial Tetartan [11].…”

Alcoholism: A Genetic Disorder?

“…Varela et al 1969, Cruz-Coke et a1 1973 claiming that male patients with alcoholic cirrhosis and alcoholism have abnormalities of colour vision suggesting an X-linked gene, partly responsible for these disorders. Unfortunately workers in other countries using more refined techniques for the testing of colour vision have not been able to confirm these findings (Fialkow et al 1966, Thuline 1967.…”
