Description

Stimulation screen structure of perimeter
Technical Field
The invention belongs to the technical field of visual electrophysiology, and particularly relates to a stimulation screen structure of a perimeter.
Background
Electrooculogram is a measurement of the electrostatic potential of the retina that exists between the retinal pigment epithelium and photoreceptor cells. According to the change of the resting potential of the retina under the conditions of light and dark adaptation, the photochemical reaction of photoreceptor cells and the functional condition of the outer retina can be reflected, and the physiological change of the eyeball position and the eyeball movement can also be measured. The electrical response of the retina comes from the complex neural network of the retina. The retinal photoreceptor epithelium has a positive potential, the pigment epithelium has a negative potential, and the potential difference between two layers can reach 60 mV. A positive potential may be passed forward to the cornea and a negative potential passed backward to the back of the sclera. When the eyeball turns to the medial canthus, the cornea of the positive pole is moved closer to the medial canthus and the posterior pole of the negative pole is moved closer to the outer canthus, whereas the opposite result is obtained by rotating the cornea to the outer canthus.
