Description

Macular fovea myopia therapeutic instrument

Technical Field

The utility model relates to a medical science field, concretely relates to foveal myopia therapeutic instrument of yellow spot center.

Background

The macula lutea is 0.35cm on the temporal side of the optic nerve disc of the fundus, is in the optical central area of the human eye, and is the projection point of the visual axis. The macular area is rich in lutein, which is darker than the color of the peripheral retina. The depression in the center of the macula, called the fovea, is where vision is most acute.

The ophthalmology medical community generally considers that too much near work and too little outdoor time are the main factors of myopia and eye fatigue. When a person gazes at one point with both eyes or one eye, the rod cells of the peripheral retina are in an inhibition state, the retina outside the macula lutea has great visual potential, and when the person gazes at one point with one eye or both eyes without movement, the function of the retina outside the macula lutea is trained and developed by using the equipment and the method to realize the effects of myopia inhibition and treatment, when the peripheral retina looks at objects with lower vision, the vision can be reduced, the effect of fog vision is achieved, and the adjustment force of ciliary muscles is further relaxed. The object image from a distance of a myope, whose focus is in the central retinal region, i.e. the macula, falls in front of the retina, and in the peripheral retinal region falls behind the retina, is called relative peripheral hyperopia. Conventional spectacles only correct the central retinal area so that the image focus moves backwards and falls on the macula, but do not correct the relative hyperopia of the peripheral retina. When light falls behind the retina, the eyeball tends to grow in length and size, allowing light to be focused on the retina, and thus myopia gets deeper.

Hyperopic defocus can promote the development of myopia, and many traditional myopia treatment devices and methods are available at present, but all have certain defects: if the curvature of the focal zone is flatter than the curvature of the retina, a portion of the focal zone may move behind the peripheral retina when treating foveal myopia, resulting in reduced image resolution at the periphery of the retina. The eye responds to peripheral defocus by elongating to cause the focal point of the off-axis rays to focus on or in front of the peripheral retina. While the peripheral retinal response may achieve the desired effect of moving the focus of the off-axis light to the front of the peripheral retina, it also results in the focus of the on-axis light being focused outside the fovea, thereby reducing visual acuity. In addition to the fovea, poor quality images of the retina periphery may play a major role in the development of myopia. When the peripheral retina does not experience sharp focus over time, the eye will elongate along the axis to focus off-axis light rays on or in front of the retina. In this regard, defocus of the peripheral retina has been shown to be the primary cause of the increased axial length signal. Ocular elongation increases the corneal to retinal distance, resulting in more on-axis rays being focused on or in front of the fovea. One adverse side effect of axial elongation is that the focal point of the axial light is displaced from the foveal recess, resulting in recurrence of previously treated foveal myopia.

Therefore, the utility model provides a simple structure, convenient operation, work efficiency is high, and accurate control through the mode of training the outer retina in macula lutea, prevents that hypermetropia nature out of focus from appearing, eliminates hypermetropia nature out of focus, lets the object image present on peripheral retina, promotes the macula lutea fovea myopia therapeutic instrument of peripheral retina rod cell function through the development to peripheral retina, has extensive market prospect.
