The discrepancy between the length of the eye axis and the degree of myopia is usually caused by an abnormality in the refractive system of the patient’s eye as well.
Under normal circumstances, the length of a person’s eye axis is about 24 millimeters, and studies have found that for every 1 millimeter increase in the length of a patient’s eye axis, the degree of myopia can increase by about 300 degrees. However, myopia is not only determined by the length of the eye axis, but also has a relationship with the refractive power of the refractive system of the eye, and the two work in conjunction with each other to finalize the patient’s myopia.
If the patient’s eye axis length is long, but the refractive power of the refractive system of the eye is weak, it is possible that the patient will not show myopia or will have low myopia. If the patient’s eye axis length is normal, but the refractive power of the eye is strong, the patient may have high myopia.
Patients with myopia are advised to visit a hospital to evaluate their condition and follow the doctor’s instructions for treatment.
