Background technique

The fundus is composed of the retina, fundus blood vessels, optic nerve head, optic nerve fibers, the macula on the retina, and the choroid behind the retina. The lesions in these parts are collectively referred to as fundus diseases. The harm of fundus diseases to people is mainly to affect the visual ability. Can cause blindness. At present, traditional treatment methods for fundus diseases include drug therapy and physical therapy, but they are often ineffective.

Near-infrared light (wavelength between 600nm and 1000nm) can promote tissue healing. Through a series of animal experiments and clinical observations, it was found that near-infrared light has a certain effect on the functional recovery of retinal and optic nerve damage in acute methanol poisoning. By promoting mitochondrial function, it improves the aerobic metabolism of cells, thereby improving the viability of cells in hypoxic and toxic environments, and inhibiting gene variation and mutation. Therefore, we speculate that near-infrared light has similar effects on fundus diseases related to mitochondrial function attenuation, such as juvenile yolk sac-like macular degeneration. For this reason, after clinical observation and laboratory confirmation, with the increase of age, the function of mitochondria and cytochrome oxidase does exist in the macular area of the fundus. Since the changes in the macular area are more serious than those in the peripheral area, it is inferred that this may be related to photodamage.
