Comparative study method for macaca animal eye axis development by lighting sources

Abstract

The invention relates to a comparative study method for macaca animal eye axis development by lighting sources. The method includes the steps: selecting a plurality of macaca animals with visual indexscreening detection values meeting requirements as experimental animals, and randomly distributing the macaca animals into N rearing cages with different lighting sources; detecting eye visual indexinitial detection values of the experimental animals one week after rearing, eliminating the experimental animals with obvious difference among the initial detection values and screening detection values, averaging the initial detection values and the screening detection values of the rest experimental animals to serve as basic detection values, and continuing rearing; detecting final visual indexdetection values of the experimental animals 6-24 months after rearing; performing comparative analysis according to the basic detection values and the final detection values to obtain analysis dataof the influence of the different lighting sources on vision development of the experimental animals. The experimental process is harmless to the animals, so that the comparative study method is a research method much closer to natural myopia development state.

Description

technical field [0001] The invention relates to a method for detecting the influence of different lighting on the natural development of the eye axis of young rhesus monkeys in a non-artificial interference state, and belongs to the fields of photobiological safety and photobiological effects. Background technique [0002] 1. Excessive growth of the eye axis is the most important physiological manifestation of the occurrence of myopia. When the length of the eye axis is greater than the normal value, in a relaxed state, the parallel light rays cannot be focused on the retina after being refracted by the refractive system of the eyeball, but converge in front of the retina, resulting in unclear distant scenery, thus produce myopia. This kind of myopia is also called axial myopia, which is the main type of myopia suffered by primary and middle school students. It is generally believed that the development of eye axis is affected by many factors, among which the relationship ...

Problems solved by technology

This design is suitable for although the myopia of rabbits, cats and dogs can be quickly induced through the lens, but this is different from the development process of myopia in the natural state

In addition, the patent does not measure and correct the light deflected and blurred by the lens, which will interfere with the explanation of the possible mechanism of myopia
