Description
Technical Field
The invention relates to the technical field of medical biological measurement, in particular to a visual target testing system aiming at different dynamic visual stimuli of photoreceptor cells.
Background
The human retina mainly comprises three cellular structures, namely a photoreceptor cell layer, a bipolar cell layer and a ganglion cell layer. In the process of visual signal transmission, various external visual information firstly reaches the photoreceptor cell layer, is modulated into signals with different time frequencies and spatial frequencies in the photoreceptor cell layer, and further reaches the ganglion cell layer through the transmission of the bipolar cell layer to carry out signal integration. There are three main types of photoreceptor cells in humans, cone cells, rods and intrinsic photosensitive retinal ganglion cells (iprgcs). The rod outer segment contains rhodopsin, is sensitive to blue-green light, is mainly used for sensing scotopic vision, and is a photoreceptor highly sensitive to light. The cone cells mainly function in bright environments and can sense fine resolution, spatial resolution and color vision. IpRGC is a third type of photoreceptor cell that contains melanoidin, is most sensitive to light at a wavelength of around 465nm, and plays an important role in pupillary light reflex and rhythm regulation.
Dynamic vision refers to the perception process by which an observer distinguishes self-movement or external relative movement through visual signal input. The motion vision provides us with a great deal of information from the outside environment, which is relevant to our life, such as motion, driving, etc. The conduction of the moving visual signal is different from the conduction of the static visual signal. At the level of retinal ganglion cells, M ganglion cells mainly conduct signals with high temporal frequency and low spatial frequency, while P ganglion cells conduct signals with low temporal frequency and high spatial frequency, so that M ganglion cells have a large relationship with movement vision signal conduction. While different ganglion cells have some variability in their association with different photoreceptor cells. Previous studies show that rod cells project mainly to M ganglion cells and less to P ganglion cells, and cone cells have no selectivity in the projection of M and P cells, so that different photoreceptors may play different roles in the conduction of motor vision, and the design of a motor visual target and a test system for the stimulation of different photoreceptors is required to research the roles of different photoreceptors in the conduction of motor vision signals. However, no similar optotypes and test systems exist.
