Treatment Scope > Ophthalmology > Myopia, Hyperopia and Amblyopia

A ray of light enter the eye is refracted by the cornea, and then, after passing through the aqueous humor, it is refracted by the crystalline lens. The anterior surface of the cornea is the major refractive surface of the eye. The cornea has a fixed focal length (focus), but the curvature of the lens changes in accommodation so that the human eye provides clear images of objects located both near and far from the eye. 

Accommodation: 

The zonule attaches at the equator of the lens to its anterior and posterior capsule and to the ciliary body between the ciliary processes. When the circular portion of the ciliary muscle is at rest it has a maximum diameter and exerts tension on the zonule to maintain the lens with a minimum curvature, thickness, and refactive power. The diameter of the ciliary muscle is smaller when it contracts, and the tension on the zonule is less. The relaxed zonule results in the inherent elasticity of the lens to become more spherical and thicker, thus increasing its refractive power. 

Myopia: 

Myopia is that optical condition in which rays of light entering the eye parallel to the visual axis come to a focus in front of the retina. The condition occurs(1) because the refractive power of the cornea and lens is too great for the length of the eye or (2) because the eye is too long for the refractive present. Myopia may be divided into three types(1)physiologic myopia;(2) pathologic or degenerative myopia and (3) lenticular myopia. Physiologic myopia, the most common type, occurs because of inadequate correlation of the refractive power of the cornea and lens with the length of the globe ,both of which are within their normal distribution curves. It has its onset usually between 5-10 years of age. It gradually increases until the eye is fully grown. 

Hyperopia: 

Hyperopia is that refraction condition of the eye in which, with accommodation suspended, parallel rays of light are intercepted by the retina before coming to focus. The condition occurs because the refractive power of the cornea and lens is inadequate for the length for the globe (refractive) or the globe is too short(axial) for the amount of refractive power present. Accommodation increases the refractive power of the lens and may compensate for hyperopia.

Amblyopia: 

Amblyopia is a condition in which a unilateral or bilateral decrease in form vision (visual acuity) occurs that is not fully attributable to organic ocular abnormalities. It is caused by deprivation of form vision, abnormal binocular interaction, or both, during visual immaturity (birth to 6 year old), it may be reversed in some individuals by therapeutic measures. 

Symptoms and signs of refractive error:

In myopia, vision is decrease for distance and is normal for near. In hyperopia, vision may be normal or slightly decreased for both near and far. Many symptoms are attributed to refractive errors. Eyestrain, visual fatigue, burning, itching, increased sensitivity to light of the eyes, headache, amblyopia, even bleeding of fundus, detached retina. 

Etiology and mechanism of Chinese medicine:

(1) Insufficiency of both congenital and acquired essence, dysfunction of internal organ. 

(2) Deficiency of liver blood and kidney essence, which can not provide the eyes with enough blood and essence. 

Treatment:

We provide treatment which can improve vision and relax muscle through the magnetic massage of the points. Practices have shown it can improve blood circulation of eyes, relief extraocular and ciliary muscles, regulate visual axis, nourish optic nerve and retina.

The treatment take 10 time, 30 minutes each time, and once a month for maintenance after seeing great improvement. The effectiveness is increased in children before 16 years old. 

This clinic research was reported in the ninth world optical meeting and was awarded the third rate medal of progress of science and technology by the world traditional medicine organization.
