For many years electroretlnography (ERG) has been used for obtaining information about the retinal physiological function. More recently, a new technique called optoretinography (ORG) has been developed. In one form of this technique, the physiological response of retinal photoreceptors to visible light, resulting in a nanometric photoreceptor length change, is measured by phase-sensitive optical coherence tomography (OCT). In our work, we focus on the development of ORG that can measure a response to a flicker stimulus. During the seminar l will show that we can detect the photoreceptor optical path length (OPL) modulation amplitude in response to different flicker frequencies in a repeatable fashion. I will also demonstrate the ability to spatially map a response to a flickering patterned stimulus
