Functional Retinography (FRG) is a technique to map the neural response in retina non-invasively with intrinsic signal imaging technique, for future application in clinical fields. We have successfully demonstrated stimulus-evoked response topography of Macaque retina, which reflects cone- and rod-induced photoreceptor function for the first time (Tsunoda, et al., IOVS, 2004, 45, 3820-6). With further technical development, FRG has a strong potential to be a new diagnostic tool for early detection of subtle (subclinical) retinal dysfunction.
This study has been conducted in corporation with National Institute of Sensory Organs.
