What are the early signs of optic nerve atrophy? What are the symptoms of optic nerve atrophy?

Hello! Song Yanmin, chief physician of the Department of Ophthalmology of Xi'an Grade 3A Traditional Chinese Medicine Hospital, said: "What are the early symptoms of optic nerve atrophy?

There are many diseases that cause optic nerve atrophy, optic nerve atrophy may not be found without professional examination, patients will find that the optic nerve conduction or optic disc boundary is pale, in fact, it is an early lesion of optic nerve atrophy, and there are other eye lesions such as glaucoma, uveitis, retinitis pigmentosa, diabetic oligomendral lesions, etc. Because after the late stage of optic nerve atrophy, the effect is poor and expensive. Yang Yang, deputy chief physician of the Department of Ophthalmology of Ma'anshan Sanjia People's Hospital, put forward his own views on optic nerve atrophy.

One is the drug**. Optic nerve atrophy can be carried out with vasodilating drugs**, which can effectively improve the symptoms, and restore some damaged optic nerves and vision by dilating the surrounding blood vessels; The second is surgery**. If the effect of the drug is not good, it can be carried out by surgery, which can also effectively improve the symptoms, and you must have a good attitude during this time.

I wish you all the best and a happy family.

Once the clinical symptoms of optic nerve atrophy occur, it is still very obvious, there are often very obvious visual field defects, there are some areas above or below that are invisible, or there will be some black screen obstruction when looking, at this time, you must go to the hospital as soon as possible, dilate the pupils to check the fundus, and at the same time improve the examination of the optic disc OCT and the examination of the computer visual field, you must see the degree of optic nerve atrophy and the scope of visual field defects.

Nowadays, many diseases may cause optic nerve atrophy, such as glaucoma, optic nerve damage caused by trauma or optic disc vasculitis, which may cause permanent atrophy of the optic nerve, so we must pay attention to protect the optic nerve, pay attention to the health of the eyes, and go to the hospital regularly to check the fundus situation.

If the lesion is found, it must be carried out as soon as possible**, if it can be detected and diagnosed early, the early ** effect is still good.

The main symptoms of optic nerve atrophy are as follows:

Clause. 1. Vision loss. This is one of the most prominent symptoms, many patients actually do not know that they are a patient with optic nerve atrophy before the examination or conclusion, he just thinks that his vision may be more obvious during this time, and it is getting worse day by day.

Clause. Second, we will find that in some patients, his vision is changing. The so-called visual field is simply the range of vision that we humans can see, and the visual field of patients with optic nerve atrophy is gradually decreasing.

Therefore, some patients will feel that they cannot see anything in the peripheral part of the eye, but can only see a piece of the area in front of them, which means that your field of vision has undergone irreversible changes.

Clause. Third, it is the change of visual function. Sometimes our patients with optic nerve atrophy have a prominent symptom that the color of their eyes has changed, and they are not color blind or color deficiency patients.

However, with the progress of optic nerve atrophy, it has the ability to see things and distinguish colors, or the recognition of colors decreases, and it cannot be clearly distinguished, so these points are the most prominent and obvious symptoms of optic nerve atrophy.

Expert tip: symptoms of optic nerve atrophy, loss of vision in the first, changes in the visual field in the second, changes in visual function in the third. The above points are the most prominent and obvious symptoms of optic nerve atrophy.

Everyone may have heard of the symptoms of optic nerve atrophy, but do you know what the symptoms of this disease are? Optic nerve atrophy can cause people's eyes to protrude, or their vision is affected somewhat, so it is a very serious eye disease. And in severe cases, it is likely to lead to permanent blindness or permanent vision loss, so it is important to pay attention to prevention.

Everyone has heard of the symptoms of optic nerve atrophy, but do you know what symptoms this symptom causes, I believe many people don't know this, in order to let you better understand this disease, let's give you a detailed introduction to the three symptoms that this symptom will cause.

First of all, let's talk about this disease, this symptom, which is a condition in which the retinal cells are damaged due to certain diseases or some reasons, resulting in changes in the shape of the retina.

And it can cause nerve fibers to change or disappear, which will lead to changes in the visual field, vision loss, and loss of vision. And it can have a serious impact on the patient's life.

This disease is so serious, in order to allow everyone to better prevent and carry out it earlier, so I will explain to you the three symptoms that this symptom will bring.

The first is vision loss, if the patient has retinal atrophy, the first symptom will be vision loss, because this disease directly affects the retina, so it is normal and the most common phenomenon to have this symptom.

The second type is scotomas in the visual field, because this condition directly causes changes in the retinal nerves or directly causes symptoms of retinal neuropathy, so it is likely to cause some scotomas in the things that the patient's eyes come into contact with, usually cyan.

The third point is that there will be some changes in the appearance of the eyes, because there are lesions in the retina, and this disease directly acts on the eyes, and the eyes may also be affected by this, and there will be some changes in shape.

What are the manifestations of optic nerve atrophy? What are the manifestations of optic nerve atrophy? There are many people who feel that their eyes are particularly uncomfortable recently, and their vision is getting worse and worse, sometimes their vision is blurry, their eyes are red, and there is blood in their eyes, which is actually the most obvious symptom of optic nerve atrophy.

First of all, optic neuroatrophy is mainly manifested by vision loss, and the eyes appear grayish or pale.

The main manifestations are changes in visual acuity and color vision, as well as visual field defects.

What are the common symptoms?

There are varying degrees of vision loss, and in severe cases, permanent visual impairment may occur.

Acquired color vision disorder, especially red-green color blindness.

Visual field defects in which the patient's visual field becomes smaller.

Optic atrophy is characterized by vision loss, with grayish-white or pale eyes.

Muscular dystrophy**:

It is a hereditary disease. According to the genetic mode, pseudohypertrophic muscular dystrophy, Becker guanidine dystrophy, and Emery-Drcifuss muscular dystrophy were X-linked recessive inheritance, while facioscapulohumeral muscular dystrophy and myotonic muscular dystrophy were autosomal dominant inheritance. Limb-girdle muscular dystrophy is inherited in an autosomal recessive manner.

At present, the most in-depth research on the pathogenesis and pathogenesis of pseudohypertrophy and muscular dystrophy is the most in-depth, and the lesion gene is located in, and the DMD gene has been successfully cloned, its size is, cDNA is 14kb, encoding a protein with a molecular weight of 427kda, that is, dystrophin, which accounts for the total muscle protein, is a cell scaffold protein, located on the inner side of the muscle membrane, the amino end binds to actin, and the carboxyl end combines with glycoprotein to form a complex, whereby the cytoskeletal membrane is connected to the extracellular glycoprotein, When dystrophin is deficient, the interaction between the normal muscle membrane and the extracellular matrix is impaired, resulting in an increase in the osmotic fragility of muscle fibers, the escape of intracellular components such as creatine kinase (CK), and a large amount of Ca2+ and Na+ influx, resulting in muscle degeneration and necrosis.

In patients with dystrophin absent or less than 3% of normal, 90% of patients with muscular dystrophy present with typical pseudohypertrophic muscular dystrophy, whereas Becker-type muscular dystrophy occurs only when the amount of dystrophin is reduced or the molecular structure is abnormal.

Although the clinical manifestations are different, the pathological changes are basically the same, the early manifestations of muscular dystrophy are the expansion of the sarcoplasmic reticulum, irregular arrangement, homogeneous degeneration of muscle fibers, with the progression of the disease, the necrosis and regeneration of myofibroblasts, followed by a decrease in the number of myocytes, obvious proliferation of endomysium, and finally manifested as the enlargement, bifurcation, hyalidity, and atrophy of muscle fibers, and muscle tissue is filled with a large number of connective tissue and adipose tissue, which can produce pseudohypertrophy. Cardiomyocytes may degenerate due to fatty infiltration and fibrosis.

Through muscle biopsy and immunohistochemistry, different protein defects can be found in the specimens.

Muscular dystrophy with mental retardation may be accompanied by developmental abnormalities of the cerebral cortex, such as macroencephaly, cortical ectopia, or other cortical dysplasia.

Vision loss caused by optic nerve atrophy is the biggest harm of optic nerve atrophy. If not active**, optic nerve atrophy leads to retinal detachment, resulting in blindness; Some optic nerve atrophy is hereditary.

1. Vision loss.

This is the most common and most injurious form of optic nerve atrophy. Patients will see blurred and unable to see clearly due to optic nerve atrophy, which will have a serious impact on normal life and work.

2. Blindness. After the optic nerve is atrophied, it cannot be active**, which leads to the continuous development of the disease, not only vision loss, but also vision loss, and eventually blindness, and inability to take care of oneself.

3. Hereditary.

Optic nerve atrophy caused by certain factors is hereditary, and if you have this disease, you need to pay attention to the situation of the next generation.

The main manifestation is vision loss, and the eyes appear grayish or pale.

: The main manifestations are vision loss and grayish-white or pale optic discs.
