OFTALMOLOGIA - MYOPIA
Myopia is a refractive error that is usually detected during childhood. Nearsighted children get very close to the object when they do close tasks, such as reading and writing.
From when it is detected up to 20 years of age, myopia can increase, sometimes so quickly that changes of glasses are needed very often. After 20 years, the variations are usually smaller and much slower. Reading a lot, poor lighting, nutritional factors or wearing contact lenses do not cause myopia or influence its evolution.
Nearsightedness of more than 6 diopters is considered "high" and needs periodic retinal checks, as retinal detachments may occur more frequently than in a normal eye.
THE MYOPIC EYE IS USUALLY LONGER THAN NORMAL
Under these conditions, the natural "lenses" of the eye (cornea and lens) cannot focus well enough on objects that are far away, which are focused in front of the retina.
Myopia may also be due to changes in the shape of the cornea or lens, although more rarely. In any case, the end result is the same: the objects are focused in front of the retina.
AT WHAT AGE CAN IT BE DETECTED?
It can be detected at any age. In young children especially when myopia is high. In school age in most cases. Myopia can appear when you grow up, especially when the cataract begins to progress.
It can cause, apart from the visual blurring from afar, headache, eye irritation, discomfort, strabismus and school delay.
IS IT ASSOCIATED WITH ANY DISEASE?
Mild and medium myopia has a greater risk than ametropia (not having diopters of any kind) to have retinal problems such as tears or detachments.
Elevated myopia is accompanied by more problems during the patient“s life such as cataract, glaucoma. Macula problems, etc.
