Swinging Flashlight Test

The swinging flashlight test (SFT) is widely used to diagnose any lesion in the afferent visual pathway which causes an asymmetric pupillary reaction in response to light, known as a relative afferent pupillary defect (RAPD). Due to the high subjectivity associated with traditional SFT, we propose an Arduino-based automated RAPD detection system.

In order to eliminate the limitations of traditional swinging flashlight test and introduce objectivity, we propose a novel approach to the swinging flashlight exam, VR-SFT, by making use of virtual reality (VR).
