Diabetic retinopathy: symptoms, causes, treatment


Diabetic retinopathy results from damage to blood vessels in the retina sensitive layer in the light of the eye on the back of the eye.The condition is a complication as TAA type 1 and type 2 , and can cause vision, from the lack of definition to the problems to see the colors and much more. If it is not treated, blindness can occur.

, which has poorly controlled glucose (sugar) levels in the blood is the main risk factor for this state, which is the most common cause of vision deterioration and blindness between Adults in the United States.

According to the Center for Disease Control and Prevention (CDC), more than 7 million Americans have diabetic retinopathy, which is expected to be doubled for 2050.

Diabetic retinopathy leads to damage to blood vessels on the retina.

Diabetic retinopathy stages

Diabetic retinopathy affects both eyes, it generally progresses through four different phases.All are distinguished by the degree and type of damage of the retina.

Symptoms of diabetic retinopathy

In the early stages, diabetic retinopathy can produce several symptoms, where appropriate.As you progress, problems with vision will arise and get worse if the condition is not treated.They may include: / P>


Diabetic retinopathy occurs when the blood glucose level is not properly controlled.

High levels of blood sugar ( hyperglycemia ) Weaken blood vessels, which causes fluid leakage in the retina and vitreous, and new cause, weak blood vessels for growing up.

Retas depend on the rich delivery of blood vessels. We can not work, because they should absorb light and send signals through the optic nerve into the brain, which will be interpreted.

The longer a person has an uncontrollable diabetes,More likely, they have to develop the recidivism of diabetic retinopathy

women with diabetes who are pregnant or who are developing gestational diabetes are increasing risk, as well as Latin, indigenous and African-Americans.Smoking also increases the risk of diabetic retinopathy.

Some complications of diabetes are associated with the development of diabetic retinopathy as aborpically, high blood pressure (hypertension) and high levels of cholesterol.

Method for diagnosing diabetic retinopathy -This is a complete test .According to the National Eye Institute, from several standard tests performed during the ocular examination, those that will help achieve diagnosis of diabetic retinopathy:

  • Visual acuity , ,What determines how well a person can see at different distances using the eye card
  • tonometry , pressure measurement inside teeye
  • Review Retina , ,In which the eye drops are placed to cause the expansion of students, which allows a clear-looking health care provider to retinal.They will be able to see changes or leaks of blood vessels, warning signs of leaking blood vessels (such as fatty sediments), swelling of the cubic meter, changes in eye lens and damage to nervous tissues.

Other tests, sometimes they are performed if diabetic retinopathy is suspected or diagnosed,Includes:

  • coherence optical tomography (October) of non-invasive image technology used to obtain high resolution cross-resistant writing Retina images
  • Fluorescein angiogram , , in which the fluorescent dye is injected into the bloodstream (usually through a vein in your hand) travels to the vessels In the retina.The retina can receive and use to zero in certain problem areas.


How to process diabetic removal, it depends to a large extent on what stage it has reached.

At first, the treatment is not needed, in addition to the aware monitoring of eye health and takes steps to improve how well it is controlled by diabetes well.Improving blood sugar control can often decrease progression of the damage of the retina. However, if diabetic retinopathy reaches an advanced stage, but any number of surgical procedures may be necessary immediately.

These include: / P>

  • Photocogpulation: Also known as laser laser focal The treatment lasers are used to stop or slowly the leaks of abnormal blood vessels.This treatment conducted at the health office or at the health office or in the eye clinic, which is likely to return blurred vision to normal, but will help prevent deterioration.
  • paneutinal photokagulation: This is Another procedure that uses lasers to compress the abnormal blood vessels.Sometimes it is called dispersion laser processing, it can also be performed in the office professional or at the ocular clinic. This can lead to the loss of some peripheral devices or night vision.
  • Vitrectomy: The small incision is made in the eye to eliminate the blood from a vitreous, as well as a scar cloth that can pull the retina.A takes place at a surgical center or hospital using local or general anesthesia.
  • Therapy Anti-VEGF: This procedure includes an injection of medications called vascular growth factor inhibitors (VEGF), on vitreous to help stop the growth of new blood vessels.VEGF inhibitors work, blocking the effect of growth signals, the body sends to generate new blood vessels. Sometimes, anti-vegf therapy is used together with the pagan photocoon.While studies of anti-VEGF therapy in the treatment of diabetic retinopathy, this approach is not yet considered the standard.

The word of obtaining medications

As with many complications of diabetes it is very possible to send diabetic retinopathy and other problems with the eyes associated with theDisease, as soon as such measures are required, provided measures are required.

The most effective thing you can do is control diabetes according to the instructions of your medical care.This includes the hechepes with the use of with an emphasis on products that are lower, low on cards and calories and nutrient-rich; be physically active; kicking the habit if smoking; regularly control blood sugar levels;and take insulin or any medication that is prescribed exactly as your doctor is indicated.

You should also be active for your eyes: Get regular exams and, if you notice any change in the view, consult the doctor immediately .
