Warning: the “invisible killer” of high myopia — pathological myopia

Abstract: in a broad sense, myopia exceeding 600 degrees is regarded as high myopia, and pathological myopia is a special group of high myopia. It refers to myopia exceeding 600 degrees, the degree is increasing, and the vision is declining, accompanied by eye axis extension and multiple fundus lesions. It is a kind of blinding eye disease. Mobile phone computer is widely used in the field of myopia. The incidence rate of myopia is increasing year by year with the popularity and updating of mobile phones and computers.

is a big country with myopia. According to statistics, the incidence rate of high myopia in China is about 1-2%. In some small areas, the incidence of myopia is even higher than 6.9%, and myopia is more and more

.

In daily life, we think myopia is wearing glasses. As long as we wear glasses, we are just like normal people. In fact, this statement is not completely correct.

■ in Ophthalmology, in terms of the pathogenesis of myopia, myopia can be divided into simple myopia and pathological myopia. Simple myopia means that after teenagers mature, the degree of myopia basically tends to be stable and will not increase. Just like people’s height, when they grow up at the age of 18, their height is basically fixed and there will be no possibility of growing taller. However, if a person grows taller all the time, it shows that growth hormone disorder must be a problem with a certain function of the body. If there is a problem, you need to see a doctor in time.

and

■ there are also such special people in myopia. The degree of myopia continues to deepen with the growth of age, from hundreds to 1000 degrees, even to two or three thousand degrees. This kind of myopia is clinically known as “pathological myopia”, also known as “malignant myopia”.

recognize the harm of high myopia

■ patients with high myopia not only need to wear heavy glasses all year round, life is extremely inconvenient, the range of vision they see is becoming smaller and smaller, and objects are deformed. For example, normal people see the size of a duck egg, while patients with high myopia may see an egg. This pain is difficult for normal people to experience and feel.

■ although this is inconvenient, there are many misunderstandings in the cognition of many people and even patients with high myopia. Many patients don’t think so. They think it’s ordinary high myopia. It’s good to wear glasses. The big deal is that glasses are thicker and heavier. As long as they can see and see clearly, they’ll be fine. In fact, they’re not.

■ ophthalmologists have found in clinical and research that this pathological myopia does a lot of harm to patients, and can produce a variety of pathological changes, such as fundus diseases: including macular splitting, macular hole, macular atrophy, retinal detachment, concurrent cataract, secondary glaucoma, optic nerve atrophy, etc., which can lead to the decline of vision, Even blind.

is known for the incidence of “high myopia”, such as

and

. Since the incidence rate of high myopia is so high, the number of people is high and the harm is heavy. We need to know more about high myopia.

■ in a broad sense, myopia exceeding 600 degrees is regarded as high myopia, and pathological myopia is a special group of high myopia, which refers to myopia exceeding 600 degrees, the degree is increasing, and the vision is declining, accompanied by prolonged ocular axis and multiple fundus lesions. It is a kind of blinding eye disease. Pathological myopia accounts for 27% ~ 33% of the myopia population. There are ethnic differences and obvious genetic tendency.

is high myopia hereditary?

■ at present, it is recognized that the occurrence of myopia is the result of the joint action of genetic and environmental factors. In high myopia, genetic factors play an important role, and environmental factors regulate and modify genetic factors. High myopia is a genetic disease with various genetic modes.

■ in clinical medicine and research, it is found that when a man with high myopia combines with a woman with high myopia (more than 600 degrees), the chance of children’s disease will be more than 90%. In the high myopia clinic of the eye specialty hospital of Daping Hospital, there are often patients with familial inheritance of high myopia, and even several generations of a family are high myopia.

■ in the face of the patient’s entanglement and pain, experts suggest that this patient can have children. Although the children may be inherited, under the current medical technology, if they are found, examined and treated early, there is still a chance of cure.

and

experts remind: regularly check

and

■ in the high myopia clinic, many patients talk to doctors about their inconvenience and pain, and remind the majority of patients with high myopia: it is recommended to go to a regular ophthalmic hospital for ophthalmic examination every six months or at least one year, especially the detailed examination of fundus. For patients with family history, they should see a doctor as soon as possible, Patients diagnosed with “pathological myopia” should be treated with posterior scleral reinforcement as soon as possible to prevent the further development of fundus lesions and protect vision.
