Myopia is a refractive error, and there are two main types of relationship between myopia and amblyopia: 1. Refractive amblyopia, mostly binocular, occurs in children or adults with high myopia, myopia and astigmatism who do not wear corrective glasses, most of whom have myopia above 600 degrees, hyperopia above 500 degrees, and astigmatism ≥200 degrees or both. The visual acuity of both eyes is equal or similar, and there is no dysfunction of binocular image fusion, so it does not cause functional inhibition of macula, and if appropriate glasses are worn in time, the visual acuity can be gradually improved. 2, refractive parallax amblyopia, because the two eyes do not see the same, the two eyes retinal imaging size and clarity is different, the higher refractive power of one macula imaging large and blurred, causing the two eyes fusion reflex stimulation is insufficient, can not form binocular monovision, thus producing passive inhibition, two eyes refractive and more than 300 degrees, refractive power of the higher often form amblyopia and strabismus. In cases where both passive and active inhibition exist simultaneously. The depth of amblyopia is not necessarily related to the degree of refractive error, but to the nature of the gaze, and the degree of amblyopia is deeper in paracentral gaze, which is similar in nature to strabismic amblyopia and is functional and reversible. This type of amblyopia is similar in nature to strabismic amblyopia and is functional and reversible. It is sometimes not easy to distinguish clinically whether the amblyopia is primary to refractive aberration or secondary to strabismus, which can be prevented by early detection and timely prescription of glasses. The symptoms of amblyopia due to myopia are 1. Abnormalities in visual acuity and refraction. The line between amblyopia and normal eye vision is not very clear, some patients complain of decreased vision, but the objective examination, vision is still 1.0 or 1.2. This may be the patient compared with their previous vision and feel the loss of vision. In addition, there may be some disorder in the optic cells of the central fossa or the subsequent conduction system, with a very small central dark spot, which is self-perceived as having visual impairment but cannot be detected objectively. 2. Difficulty in divided reading or crowding phenomenon. When checking visual acuity with the same sight marker, illumination and distance, the values measured by different intervals of sight markers are different. The difficulty in reading is a characteristic of amblyopia. Difficulty in reading is the ability of the amblyopic eye to recognize individual visual standards better than a set or dense visual standard. This means that the ability to discriminate between single open fonts on the visual acuity chart (e.g., the letter E) is better than for lines of words. Can myopia caused by amblyopia can take the driver’s license test Driver’s license test requires corrected visual acuity to reach certain standards, please consult your local driving school for related issues, combined with the corrected visual acuity of the amblyopic eye. How to treat amblyopia caused by myopia The first is for amblyopia in order to promote good vision development in both eyes, amblyopia treatment methods include: wearing glasses, wearing eye patch cover, orthoptic vision training. The effect of the amblyopia treatment device on the amblyopia caused by myopia amblyopia training device is a very good treatment of amblyopia a physical method, the effect varies with the age of the child and the degree of compliance with medical advice.
