Chronic active hepatitis and mesopic vision in aged and non aged patients.
The time of macular functional-recuperation after dazzling has been evaluated in 46 patients of both sexes with ages between 26 and 65, with chronic active hepatitis (CAH). Knowing that the macular recuperation time, even under physiological conditions, increases after the age of 40, we divided these subjects in two groups: under 40 years old (20 cases) and over 40 years old (26 cases). Patients with CAH show a noticeably increased frequency of pathological times especially in those over 40 years old. In this group the pathological cases are 96,15% compared to 60% found among those under 40. The reason for this behavior is only hypothetic. However, the importance of the results must be underlined, as during biological and clinical remission of chronic liver disease patients of working age hold jobs where weakness of mesopic vision could cause serious accidents of legal-medical interest.
