"At least 10% of students have called refractive errors - nearsightedness, astigmatism and farsightedness."
On July 10, is the World Day of Ocular Health, date established by the World Health Organization (WHO) and recognized by the Brazilian government, through the Ministry of Health, so that people reflect a little about the importance of good vision and on how to stay healthy this is one of the most important ways from the beginning of life.
WHO estimates that, worldwide, about eight million school children have some form of visual impairment, and only 25% of them have symptoms. In Brazil, about one fifth of children in this age group also already have some ophthalmologic change - data is the Brazilian Council of Ophthalmology (CBO).
As the vision grows to five years of age, a time when children are starting their school life, parents should be alert to potential problems. At least 10% of students have called refractive errors - myopia, astigmatism and hyperopia.
"About 80% of cases of loss of vision could be avoided if diagnosed early".
The habit to consult with an ophthalmologist who is the doctor who specializes in eye health, should start as soon as possible. Many eye problems have no symptoms or only present at later stages, when the visual damage is irreversible. About 80% of cases of loss of vision could be avoided if diagnosed early.
The little eye test is the first assessment to be carried out even in newborns. It diagnoses, among other diseases, cataract and congenital glaucoma. The child should also routinely perform an ophthalmologic consultation in preschool. The frequency of further consultation is guided by the physician according to the case. Parents should also be alert to changes in the color of the eyes, excessive tearing, eye discharge, deviations in the position of the eyes and deficiencies in school learning, which can be the first signs of serious problems.
Compared to adults, the recommended is visiting the eye doctor once a year. The clinical examination and other tests can diagnose early various diseases if not treated can lead to blindness.
In addition to regular ophthalmic examinations, simple steps can help keep your healthy vision. Wear caps, hats and sunglasses with UV protection to protect your eyes in the summer period when the sunlight is strongly reflected. Never wear contact lenses without prescription and medical supervision. Mid-term computer use with breaks to prevent drying of the ocular surface are simple measures that help preserve your vision.
Learn a little about the most common diseases
Myopia - A so-called refractive errors. The anteroposterior diameter of the eye is higher than normal and the image is formed before the retina. The view is good for objects that are close but becomes insufficient to clearly see those who are at a greater distance. The correction of myopia can be made with use of glasses, contact lenses and also surgeries, depending on each case.
Hyperopia - Who has hyperopia has the opposite visual sensation who has myopia. The eye is usually lower than normal and the image is formed after the retina. The patient uses convergent lenses, also known as positive by glasses or contact lenses.
Astigmatism - is a refractive error caused by an irregularity of the cornea that causes distortion of the image. Depending on the type of astigmatism, it can cause eyestrain, photophobia, and prevent clear vision for far and near.
Glaucoma - is the general name of a group of diseases that cause atrophy of the optic nerve. The main reason is the increase of intraocular pressure. It is also related to old age, family history and ethnicity (in Brazil is more common in African descent). Causes progressive and irreversible visual loss if not controlled. Hence the importance of early diagnosis. The treatment is done with medications (eye drops to lower eye pressure) and by laser or surgery, depending on the case.
Cataracts - consists of the partial or total opacity of the lens or its capsule. Trauma, advanced age, diabetes and drug use are among the factors that can trigger the disease. The symptoms are described as a progressive blurring of vision. Congenital Cataracts are a leading cause of childhood blindness and can be hereditary or be linked to infections acquired by the mother during pregnancy. Prenatal examination in this second case is the way to prevent the disease in children.
Strabismus - is an ocular disorder in which the eyes are misaligned. It is more common among children, but can also occur in adults. When the shift occurs in the first five years of life and is not treated properly can compromise irreversibly the development of vision in the affected eye. the cause should be investigated, which may include neurological disorders, brain tumors, trauma, thyroid problems, among others. Surgery is indicated in some cases.
