Abstract: Amblyopia only occurs in young children. Binocular amblyopia generally develops gradually from birth to the age of 9. In this development period, amblyopia can be caused by strabismus or loss of form perception. Amblyopia will not occur after the age of 9 even if there are the above reasons.
amblyopia and myopia are not a disease at all. These two diseases are essentially different.
myopia is an eye disease caused by the lengthening of the eye axis caused by excessive tension of the eye regulating muscle ciliary muscle or heredity. Most of the corrected visual acuity can return to normal after wearing glasses, while amblyopia is a kind of visual function retardation and disorder, often accompanied by strabismus and high refractive error, and the visual acuity can not be corrected to normal after wearing glasses.
1. Amblyopia only occurs in monocular patients. If two eyes are used alternately, amblyopia will not occur.
2. Amblyopia only occurs in young children. Binocular amblyopia generally develops gradually from birth to the age of 9. In this development period, amblyopia can be caused by strabismus or loss of form perception. Amblyopia will not occur after the age of 9 even if there are the above reasons.
3. Abnormal vision and refraction. The visual acuity boundary between amblyopia and normal eyes is not very clear. Some patients complain of decreased visual acuity, but the objective examination shows that the visual acuity is still 1.0 or 1.2. This may be that the patient feels vision loss compared with his previous vision. In addition, there may be some obstacles in the visual cells of the central fossa or the subsequent conduction system, with very small central dark spots, conscious visual impairment, which can not be found objectively.
4. Reading difficulty or congestion. When visual acuity is checked with the same visual markers, illumination and distance, the measured values are different with different intervals of visual markers. Dyslexia is a characteristic of amblyopia. Reading difficulty is that amblyopic eyes have better ability to recognize individual visual targets than collective or dense visual targets.
symptoms of myopia
myopia is a refractive state in which the focus falls in front of the retina after the parallel light passes through the refractive system of the eye without adjustment. So myopia can’t see the distant target.
amblyopia is a kind of problem that the eye bottom cells do not develop well without effective light and clear image stimulation. The treatment of amblyopia in children needs time and patience. The treatment effect of amblyopia is related to age and fixation. It is better after 3 ~ 6 years old and worse after 8 years old; Central fixation was better, and paracentral fixation was worse.
“Compared with myopia, amblyopia is more harmful. It not only has low vision and can not be corrected, but also causes strabismus, which affects the beauty and children’s physical and mental development. More importantly, amblyopia children often have no stereo vision. If they are not treated in time, they will not be competent for driving, mapping and fine work when they grow up, which will seriously affect children’s quality of life, self-confidence and work future 。”
