title: [Pupillary diameter and pupillary reactions in heroin dependent patients and in patients participating in a methadone and morphine replacement program].
abstract: The computer-assisted static and dynamic light evoked pupillometry (TV-pupillometer 1050, Whittaker Corp.) had been proved to be a sensitive procedure for assessment of the effect of psychoactive drugs. Therefore, this method was used in 26 heroin dependent patients (mean age 24.42 years), 20 methadone substituted patients (mean age 29.75), and 20 morphine-substituted patients (mean age 30.65 years) to answer the question whether there were no differences within the patient groups but significant differences between the patients and healthy normals. Indeed, pupillary diameter (vegetative activation) as well as relative change (pupillary reagibility) showed no significant differences between the heroin dependents, the methadone substitution group and the morphine substitution group. However concerning pupillary diameter and relative change the patient groups differed significantly from the healthy controls. Onset latency revealed no differences within the patient groups and between patient groups and healthy controls respectively. Thus the variable pupillary diameter and relative change could be used to assess the additional application of opiates in patients participating in a substitution program.
