Retinal degeneration

Retinal degeneration's disease overview

What is

What is retinal degeneration?

Retinal degeneration is the term to refer to the lesions of the retinal cell layer in the eyes, in which the macular degeneration is the most dangerous disease of degeneration. Retinal retinal . Causes of retinal degeneration are common are systemic diseases such as diabetes or hypertension. Diabetes is the most common cause of retinal degeneration in the US in 2008.

Is retinal degeneration dangerous?

Although retinal degeneration, despite not being fatal, it causes impairment of vision, eventually leading to blindness, adversely affecting the psychology of patients and family members. Degeneration of diabetes due to diabetes is the leading cause of blindness in the group of people in working age. Retinal degeneration is found in 5% of the causes of blindness worldwide and is considered by the World Health Organization as a top priority eye disease.

Early detection and retinal degeneration treatment promptly help improve the disease prognosis, slow the progression of the disease and preserve the vision of the patient.

Causes of Retinal degeneration's disease

The retina is provided by small blood vessels from the central retinal artery. The factors that damage these blood vessels affect the blood supply to the retinal cell layer are considered The cause of retinal degeneration . Can be divided into two causes of the disease as follows:

Retinal degeneration does not increase birth:

Blood flow comes to raise abnormal retinal cells, caused by direct lesions or the result of the regeneration of blood vessels that nourish the retina. There are three main mechanisms of damage in non -hypertension: destroying blood vessels, direct retinal damage and blood vessel obstruction. Many causes of Retinal degeneration do not increase the proliferation including:

  • Hypertension: High pressure in the blood vessel system makes the artery wall thicken, including retinal feeding arteries, reducing blood flow efficiency to the retina. This decrease in tissue ischemia leads to retinal damage, causing hypertension.

    • Atherosclerosis: also causes artery narrowing and reducing blood flow to the retina.

    Premature birth: The retinal cells are directly damaged from birth, called retinopathy due to premature birth. radioactive: radiation causes direct damage to retinal cells. Ray retinopathy can be a complication of cases of radiation therapy for tumors in the neck.

  • Sickle blood cell disease: The body responds to sickle cells by increasing blood cells to increase blood levels. From there, the flow rate slows down, especially in small arteries such as retinal arteries, eventually reducing blood flow to the retina. In this case, blood clots are also easier to form, preventing blood flow to the retina, causing cell death.
    • Hydrophometical degeneration disease

    This is a case related to the abnormal growth of blood vessels. Typically, vascular proliferation is the natural process of development and tissue formation. When the rate of high vascular proliferation increases, the blood vessels overgrow are called the new vessels. These excessive blood vessels are often fragile, weak and ineffective for retinal tissue. This makes the degenerative retinopathy with worse prognosis because of the higher risk of vascular bleeding often leads to loss of vision and blindness.

    Many causes mentioned in retinal degenerative disease can also cause increased retinal degeneration in the later stage. Diabetes, causing diabetic retinopathy, is the most common cause of hypermenet retinal disease in the world.

    Other reasons
  • genetic mutations are rare causes of retinal degeneration. Genetic mutations are often associated with X chromosomes, including the NDP gene, causing Norrie, Fevr and Coats. Injury, especially at the head and some diseases can also cause retinal degeneration. In older patients, the aging process along with external impacts such as dust is also the cause of Degeneration of retinal retinal age .
  • The process of aging due to high age and the impact of environmental pollution of dust, the diet is not guaranteed, causing the yellow carotenoids to degenerate and hurt. Causing the function of the gold spot, greatly affecting the eyesight of the eye.

    • Symptoms of Retinal degeneration's disease

    Many people have a disease but do not show any symptoms, so they often come to the examination very late, limiting the effectiveness of treatment. Patients need to identify the following signs of retinal degeneration

  • Reduce vision, blurred vision. If vision loss only occurs in one eye, the patient is often difficult to notice because the healing eye can see clearly
  • Hemorrhage lens
  • Appears blind spots in the immediate future
  • The naked eye does not hurt.

    • Diseases often manifest symptoms when in the late stage, difficult to treat. So when encountering any abnormal symptoms, patients need to see eye specialists for examination, consultation and treatment.

    Transmission route of Retinal degeneration's diseaseRetinal degeneration

    Pathology Retinal degeneration is not transmitted from patients to healthy people.

    People at risk for Retinal degeneration's disease

    Those who carry the following characteristics are at higher risk of retinal degeneration:

  • Having eye refractive defects like nearsightedness
  • Smoking
  • Poor nutrition

    • obesity

  • Family history of people with retinal degeneration

    • Diabetes

    Hypertension

    Women are at higher risk than men, especially in degeneration.

    Prevention of Retinal degeneration's disease

    Measures to prevent retinal degeneration:

  • Eat nutritious, green and fruit
  • Healthy lifestyle, maintaining weight at a balanced level
  • No smoking

    • Good control of chronic medical diseases such as diabetes, hypertension, atherosclerosis by adhering to good treatment and re -examination according to appointments.

    Diagnostic measures for Retinal degeneration's disease

    diagnosis of retinal degeneration is performed by eye specialists, through measures:

  • Measurement of vision
  • Soi bottom: is a measure to help diagnose retinal degeneration. Small doctor of pupils then retinal cell layer.

    • Retinal degeneration's disease treatments

    Refrigence of retinal degeneration includes treatment of the cause of the disease and the treatment of symptoms of the disease. Some treatments for disease:

  • Laser optical therapy: This is a standard treatment for many diseases retinal degeneration . Evidence shows that laser therapy is quite safe and improves visual symptoms in retinal degeneration related to sickle blood cells and diabetic retinopathy. >
  • Vascular Endothelial Growth Factor (VEGF): In recent years, blood vessel growth control or vascular proliferation is a new road is a new path promising. Using VEGF anti -VEGF drugs such as Bevacizumab or Pegaptanib shows a significant reduction in vascular proliferation. Research proves that VEGF anti -VEGF drugs when used in combination with laser therapy to treat retinopathy due to premature birth bring more efficiency.
  • Treatment with versatile stem cells: to replace the dead retinal cells that are unable to recover. This group of stem cells is usually taken from the patient's skin cells to ensure immunodeficiency and avoid the phenomenon of removing pieces. This is an advanced method, bringing a future to expect for patients retinal degeneration . Currently, this method is being studied in many countries and has made many advances in recent years.
