Tear (Bong) retina

Tear (Bong) retina's disease overview

retina is a thin nerve layer on the inside of the eye. When the light enters the eyes, it penetrates the cornea and the lens and is converged in the retina, then transferred into neurological signals and sends the opposite information to the brain through the optic nerves. . The function of the retina is like a movie in a camera, which records the images and things outside, and then transmits it to the brain. So we can recognize the world around.

Retinal disease is the common name of some eye diseases caused by disorders in the retina (also known as the eye bottom). It is the second row, after cataracts in diseases that can lead to blindness for patients. The most common of which is the disease retinal peel and diabetes retinopathy.

Tears retinal retina is the condition of the retinal tissue layer from the normal position inside the eye. Initially, the cause may be due to a small tear on the retina, causing the fluid in the eye to overflow under the retina, gradually separating the retina from the original position. At that time, the retina will not be nurtured, resulting in a mighty vision (partial vision loss) or completely blind if not diagnosed and treated promptly. This is an emergency medical eye. Patients may suffer permanent vision loss if not treated within 24 to 72 hours. 

In most cases, patients with retinal peeling often have very clear warning symptoms, as long as patients are not subjective, they can easily detect abnormal signs of the disease, Early detection and treatment will help improve vision for patients.

Causes of Tear (Bong) retina's disease

  • Retinal retina occurs when there is one or more tears on the retina. At that time, the glass fluid inside the eye will flow through the hole and overflow down the retina, gradually separate the retina from the nourishing tissue layer below.
  • The tear is formed from retinal degeneration, especially Chu Bien retinal degeneration. People with a history of eye injury, severe nearsightedness, hemorrhage of retinal glass, diabetic retinopathy ... are those who are at higher risk of retinal peeling than normal people.
  • Chu Bien retinal degeneration can be encountered in all subjects but often encountered in people with severe nearsightedness.
  • Cases of Chu Bien retinal tear can occur when the phenomenon of post -glass peeling occurs, or encountered at the age of 60-70 years old.

    • Eye injury can cause retinal tear due to shock or chu border retinal necrosis.

    Retinating retinal football class

    Clinically divides the retinal pockeries into 2 types:

  • Nguyen Phat retinal retina: due to one or more holes or tears in the sensitive nerve. Therefore, it is also known as the retinal peeling with tear.  
  • Secondary retinal detachment: is a condition of liquid deposits in the lower retina but not due to the tears or holes of the sensitive nervous layer but secondary after a process Pathology of retinopathy, glass or eve.

    • There are two secondary retinal football groups:

  • One is the retinal detachment: the abnormal newly sticky organization on the inside of the sensitive nerve of the retina is shrinking and separating. This type often occurs in patients with diabetes and the progression of the disease is quite silent and not too fast.
    • two is the retinal retina: The fluid leaks into the area under the retina, but without any scratches or tears on the retina. This type is usually caused by retinopathy diseases, including inflammatory disorders or eye injuries. These diseases cause retinal blood barrier disorders or retina, thereby facilitating the glass fluid that can leak into the lower retina.

    Symptoms of Tear (Bong) retina's disease

    Clinical symptoms

    Retinal peeling does not cause pain but only visual disorders

    and vision loss:

  • Seeing the flashing light at the corner of the eye (blinking);
  • See many black dots (flying flies) or a black film that covers the eyes. In most cases, these symptoms do not indicate serious problems. In some cases, the unexpected appearance of streaks or light spots may be a sign of retinal peeling.
  • If there is a large patch of retinal peeling, the patient may feel like there is a dark patch that covers the eyes, gradually encroaching towards the center. When passing through the royal point, the patient will see a lot of blurred vision and fast.
  • If the retina is all, the patient sometimes only distinguishes darkness.
  • In some cases, the retina can progress silently until most of the retina is peeled off. Such special cases, patients may pay attention to the appearance of a shadow in some places in their vision.
  • Severe cases, retinal peeling will blur the central vision and lose significant vision in the eye.
  • Some cases of sudden occurrence and patients often lose total vision in one eye. The rapid vision loss may also be caused by bleeding into the glass fluid, which occurs when the retina is torn.
    • Subclinical symptoms
  • Soi bottom of the eye (need to be done by specialists): Can see a retinal, torn or pit pit. .

    • Eyeurgic ultrasound: Helps to survey the image of the retina and other internal structures. This test usually provides information that needs to be determined whether the retina separation.

    People at risk for Tear (Bong) retina's disease

    Retinal football is more common in people over 40 years old. However, the disease can also occur at any age. The disease affects more men than women.

    Subjects at risk of retinal peeling include:

  • Heavy myopia (> -6.00d).
  • Has had a retina on one eye.
  • Family history of people who have had retinal peeling.
  • Early eye surgery, for example: removing cataracts.
  • There are diseases or eye disorders, such as retinal separation, uveitis, pathogenic pathology or chu Bien retinal degeneration (Lattice deGeneration)

    • After trauma or wounds piercing the eyeball, the retina may be peeled, accompanied by a tear and other lesions of the eyeball, eyelids. Usually in this situation, the retina will be detected promptly when the person who is injured comes to examination at the eye specialist facilities

  • Children rarely have retinal peeling. If there is often due to the congenital defects of the retinal glass or the congenital myopia.

    • Prevention of Tear (Bong) retina's disease

  • Examining an eye specialist as soon as there are symptoms of flying flying or flashing or having a dark area in the vision.
  • Glasses when playing sports or using tools;
  • Control blood sugar and often see a doctor if you have diabetes;

    • Annual eye exams, especially if you are at risk of retinal detachment.

  • Patiently patients should have eye exams every 6 months.
  • When one eye has peeled the retina, you must check the other eye immediately to detect new lesions and use laser to treat.

    • Tear (Bong) retina's disease treatments

    If the retina is torn but the peeling has not occurred, the quick treatment can prevent the appearance of completely peeling. If the retina is peeled, it is necessary to be treated with surgery.

    There are many treatments for retinal football. Some methods that help treat small tears and holes, including:

  • Laser surgery - Small stains are performed around the torn hole to help "weld" the retina to the old position.

    • Cryopole (high intensity cooling) - Treatment by frozen can also treat tears or small holes. High intensity cooling in the areas around the hole and help attach the retina to the old position.

  • Gas Injection (GAS Injection) - In this method, the doctor will pump an air bubble into the eyes. The doctor may perform this method in combination with laser or cryopexy treatment. Air ball can help push the retina back into the eye during laser or cryopexy treatment that helps the retina to close to the old position, the air ball can disappear after a week.

    • Most cases of retinal detachment are treated with surgery, including:

  • Pidelopathy: Mountains to the retina into the bottom layers from the outside. This method is often used in young people with heavy nearsightedness, ripped retina not over the back of the extreme or without too many holes.
  • Cutting glass, intraocular laser and pumping air or inner long eye silicon, which causes retina from the inside.

    • After surgery, vision may increase or the same or decrease depending on the time of peeling and severe or mild peeling. If the retina has not been through the royal point, that is, the center of the patient is not affected, the vision results will be high. If peeling through the royal point, the recovery depends on the time of peeling and coordinated lesions. In some cases, due to serious illness, it is necessary to operate one or twice again and sometimes use special drugs pumped into the eyes to make the retina again again.
