Pupillometric evaluation of patients suffering from age related macular degeneration (AMD): a comparative study with electrophysiological and optical methods

Materials and methods A total of ten subjects were included in this study: five patients with age-related macular degeneration (AMD) and five subjects with healthy eyes matching sex and age. Patients with AMD had stage 4 exudative AMD with presence of a choroidal neovascular membrane at the macular region. Mean and standard deviations of the pupil size, minimum/initial radius (%), final/initial radius (%) and maximum acceleration were calculated using the student's T-test for both control subjects and patients.
