|To distinguish between true and false myopia|
| Once the child is suffering from myopia, parents will be very anxious, and often consult "myopia with rule it?" "My child is true or false myopia myopia?" This is genuine need to know myopia.
The so-called pseudo myopia is a true myopia fatigue before, if this state can not be mitigated, eyes organic changes have taken place to form a true myopia. Dilation needs to be done to determine genuine myopia optometry. Cycloplegic refraction to mention the parents would tense up, "dilated eye harmful?" Dilated eyes of the purpose is to relieve fatigue, tension adjustment so that the muscles relax, so that the refraction is found to be accurate. If the dilation can be achieved after the uncorrected visual acuity of 1.0, that is "pseudo-myopia" can be cured in the short term, such as medicine, acupuncture, ear acupuncture and physiotherapy equipment buried use, can relax tense muscles, relieve fatigue, vision returned to normal. If not treated, as long as the eye looks into the distance, pay attention to rest, vision may also be restored.
If uncorrected visual acuity after dilation less than 0.8, is the "true myopia" of the. Once the formation of true myopia is irreversible, it is organic changes occurred in the eye, the eye longer front and rear axle, the outside world through the eyes of the refractive system images imaging of the retina before, there is no clear images of the retina, of course, there will be no good vision of the. This organic change in addition to surgery, any method can not be reduced to the eye, refractive error change, which is difficult to cure the causes of myopia.
Present a variety of refractive eye surgery is the only cure myopia, reduce the refraction method. For example, the excimer laser keratectomy (referred to as PRK), laser in situ keratomileusis stroma surgery (referred to as LASIK), are under computer control, using a laser to corneal stromal layer elastic layer and a part of tissue decomposition, the formation of small volatile fragments, flattening the cornea curvature, in order to achieve the purpose of correction of myopia. However, these operations must wait until after the age of 20, before the eye stops growing. Since these operations only in the cornea to make some physical changes, so the degradation of pathological myopia fundus can do nothing, because post-operative pathological myopia myopia continued to deepen, but also a period of time to re-wear glasses.
