Abstract

Autonomic Neuropathy is one of the complications of diabetes because it causes damage to the nervous system and one way to access it is through the analysis of the pupillary reaction. This study aimed to perform dynamic pupillometry in patients with diabetes. A video acquisition system was developed to record pupil movement exposed to light stimuli, being applied to 45 volunteers at SEMPR-HC at UFPR. 90 pupillometry videos were obtained. CNNs YoloV2 and RetinaNet were applied to the images evaluating the detection of the iris and pupil. RetinaNet achieved better performance for IoU greater than 90%. The differences between the groups with and without neuropathy appeared in pupillary maximum dilation, plateau, and re-dilation velocity.
