Beware stroke eyes, recognize the causes and treatment

Stroke not only occurs in the brain, but can also occur in the eye. Medically, eye stroke is known as retinal artery grafting. This condition occurs due to blockage of blood vessels in the retina. Learn more about the causes of eye stroke and its treatment.

Stroke in the eye occurs when blood vessels in the retina experience blockages caused by constriction or blood clotting. This makes the blood supply from the heart to the eye and vice versa to be reduced. In some cases, the blood vessels in the clogged eye will eventually rupture, causing blood to spill onto the retinal surface resulting in retinal swelling and blurred vision.

Causes of Eye Stroke

Eye strokes can be caused by blood clots that form in the retina, or from other organs that are drained into the retina. In addition, this blockage can also occur when plaque clogs the retinal vessels.

Certain diseases, such as diabetes, high blood pressure, high cholesterol, heart disease, glaucoma, cardiovascular disease and blood disorders, can increase your risk of having an eye stroke. Not only that, there are other factors that can also increase your risk of eye stroke, including:




  • Being over 40 years old.
  • Active smoker.
  • Using hormonal contraceptives, such as birth control pills.
  • Ever had an eye injury.
  • Suffering from kidney disease.
  • Has a blood clotting disorder, such as sickle cell anemia.
  • Narrowing of the blood vessels of the neck (carotid).
  • Heart rhythm disturbance.
  • Vasculitis, the inflammation of the walls of blood vessels.

Eye Stroke Symptoms

Generally eye stroke occurs only in one eye only. Symptoms of this disease can appear slowly within a few hours, a few days, or it could happen suddenly. Here are some of the symptoms that can arise in an eye stroke:

  • Typical symptoms of this disease is a vision disorder that is not accompanied by pain complaints on the eyes. But sometimes the pain in the eyes can appear.
  • Floaters, views like dizzy or the appearance of white spots on the eyesight.
  • Blurred vision that continues to deteriorate in part or all of your vision.
  • Total loss of vision can occur slowly or suddenly.

 

If you experience any of these symptoms, consult your ophthalmologist immediately. Without rapid and precise treatment, eye strokes can cause a variety of eye complications, including:

  • Macular swelling, which is inflammation of the macula or the central part of the retina.
  • Neovascularization, ie the appearance of abnormal blood vessels in the retina.
  • Neovascular glaucoma, the painful pressure from the formation of new blood vessels.
  • Loss of permanent vision or blindness.

Diagnosing Eye Stroke

Whatever the cause, symptoms of visual disturbance that appear sudden and disrupt daily activities are conditions that need to get examination and treatment from the doctor as soon as possible. At the beginning of the examination, the doctor will ask for a medical history that may be the cause of eye stroke, then perform physical examination of the eyes with a special tool called ophthalmoscope, and perform pressure checks in the eyeball. In addition, there are several further examinations to be performed to diagnose eye stroke, including:

  • Field test

Examination used to test eye vision or eye view.

  • Eye angiography

Medical procedures use contrast substances injected into the bloodstream. Eye angiography is performed to determine which blood vessels are blocked.

  • Optical coherence tomography (OCT)

An imaging test used to detect abnormalities occurring within the retina.

  • Slit-lamp

Retinal examination using a special microscope, to find out various complaints or abnormalities in the retina.

 

Generally eye strokes are caused by other diseases, so doctors will suggest you undergo some additional checks, such as blood pressure measurement, blood sugar levels, cholesterol levels, and heart examination.

Treatment for Eye Stroke

Treatment of an eye stroke depends on the underlying disease. Some medications that are generally given by an ophthalmologist within a few hours after the eye stroke symptoms begin to arise, namely:

  • Massage the area around the eyes to widen the blood vessels in the retina.
  • Provide medicines, such as blood clot breakers, corticosteroids for the eyes, and medications to lower the pressure inside the eyeball.
  • Inhale a mixture of carbon dioxide and oxygen to make the blood vessels of the retina widen.
  • Throw some of the searches out of the eye so that the blood flow to the retina returns to normal.
  • Laser therapy.
  • Provide high-pressure or hyperbaric oxygen therapy.

 

In addition, other conditions that cause the onset of blood clots should also be treated. The faster the treatment is given, the more chance you will save your vision.

Eye Stroke Prevention

Although eye stroke can not be completely prevented, but you can do several things to reduce the risk of eye stroke. Some precautions you can take:

  • Quit smoking.
  • Controlling blood sugar levels, if you are at risk or suffering from diabetes.
  • Make sure your blood pressure is always within normal limits.
  • Routine check your cholesterol levels. If too high do diet, exercise regularly, and take medication to help lower cholesterol.
  • Maintain ideal weight.

 

In addition, regular medical check up and eye examination to the doctor is one of the first steps to avoid the appearance of eye stroke. Medical check-ups need to be done to detect early risks of eye-stroke diseases, so they can be treated immediately before complications arise in the eye.
