Tool for detecting vision of experimental animal

Abstract

The invention relates to a tool for detecting the vision of an experimental animal, wherein a vision tester barrate is in a drum shape, the inner wall of the vision tester barrate is provided with bargrating sighting marks uniformly spaced along a circumferential wall, and the vision tester barrate is placed on a base; a motor is arranged below the vision tester barrate and controls the axial clockwise / anticlockwise rotation of the vision tester barrate; an illuminating light source is positioned right above the center of the vision tester barrate and is fixed on a fixing frame; the fixing frame is placed at one side of the vision tester barrate, a CCD and a computer are both placed at the other side of the vision tester barrate, and the CCD is connected with the computer through a data wire. The stepping type motor drives the vision tester barrate, the motion of the bar grating sighting marks positioned on the inner wall of the vision tester barrate leads to the regular and stable optokinetic response of the experimental animal, special software synchronously records response tracks, then corresponding analysis software analyzes data, and experimental operation and data analysisare realized in two steps, thus experimental time is shortened.

Description

technical field [0001] The invention relates to a visual inspection tool for experimental animals. Background technique [0002] In the study of myopia, in order to understand the mechanism of myopia, all experiments are carried out through animal models, and chickens, tree rats, monkeys, guinea pigs, etc. are generally used as models. However, in the process of experimental intervention, some animals of the same species are sensitive to the experimental intervention, while others are not, resulting in great variation in the experimental results. For the experimental intervention of the myopia model mediated by the clarity of the retinal image, the visual acuity of the experimental animals has a significant impact on the experimental intervention. Experimental results play an important role, such as: 1. Is the vision of experimental animals that are not induced by the same experimental intervention lower than that of experimental animals that are easily induced by myopia? G...

However, in the process of experimental intervention, some animals of the same species are sensitive to the experimental intervention, while others are not, resulting in great variation in the experimental results. For the experimental intervention of the myopia model mediated by the clarity of the retinal image, the visual acuity of the experimental animals has a significant impact on the experimental intervention. Experimental results play an important role, such as: 1. Is the vision of experimental animals that are not induced by the same experimental intervention lower than that of experimental animals that are easily induced by myopia? Generally, about 20% of animals that undergo form deprivation to induce myopia fail to induce myopia
