[Several functions of the visual analyzer in chronic alcoholic patients].

The authors examined 615 patients with chronic alcoholism. The study demonstrated an increased number of individuals with myopia, presbyopia, amblyopia, angiomas and angiosclerosis among them as compared to that of the general population. The frequency of optical nerve atrophies in the patients was not high (0.32%). In 205 cases the function of colour sensory and darkness adaptation was determined. The highest frequency of colour sensory was in the group of patients with the withdrawal syndrome. Eventually this function had a tendency towards restitution. The velocity of darkness adaptation was drastically changed in patients with chronic alcoholism but it was also reversible.
