Retina Blood Vessel Disorders

Fluorescence angiography can help determine the extent of the damage and plan treatment. To destroy abnormal blood vessels that can be used laser.

DEFINITION

Abnormalities of blood vessels leading to the eyes may be bleeding, an inadequate supply of blood and blood vessel blockage. Serious consequence is damage to the retina, which sometimes persist and cause impairment of vision and even blindness.

Retinopathy ARTERIOSKLEROTIK

In this situation, the small arteries that carry blood to the eye had a partial blockage due to thick walls.

By using the ophthalmoscope, can be seen the thickened blood vessels and other instructions from the declining supply of blood to the retina.

Thickening of the blood vessel itself usually does not interfere with vision, but it is an indication that the blood vessels in the eyes and other body parts do not need to be healthy so that preventive measures and treatment.

Hypertensive retinopathy

Hypertensive retinopathy is damage to the retina caused by high blood pressure (hypertension). This disease occurs when blood pressure is very high (eg in malignant hypertension and toxemia gravidarum).

Hypertension can cause damage to blood vessels inside the eye. The higher and longer hypertension progresses, the more severe the damage.

Severity of retinal damage (retinopathy) is described by the scale of I to IV. On the degree I normally can not find the symptoms. On the degree of optic nerve swelling IV (called papilledema) and macular (central vision in the retina), which can cause vision impairment.

In later stages, blood can seep into the retina. Patches of retina damage from lack of blood supply and eventually the fat will accumulate in the retina.

In addition to visual impairment, the patient can feel a headache.

By using the ophthalmoscope, we can see the narrowing of blood vessels and excess fluid oozing from blood vessels. Other tests are usually performed fluorescence angiography.

The only treatment for hypertensive retinopathy is to control blood pressure.

Retinal artery blockage

Retinal arteries are major blood vessels that carry blood to the retina. If the retinal artery is blocked, there will be sudden blindness without pain.

This blockage can be caused by atherosclerosis, blood clots or fatty deposits (fat usually comes from a broken bone marrow and enter the blood stream as an embolus). Other causes are inflammation of blood vessels in the head (temporal arteritis).

Dilation of retinal arteries can be done by inhaling a mixture of carbon dioxide and oxygen. In this way the blockage will move down, thereby reducing the retinal area affected.

Can be given an anticoagulant to prevent clot formation or to prevent the further spread of blood clots (which can lead to stroke).

Retinal vein blockage

Retinal vein is the main blood vessel that carries blood from the retina. Blockage of the retinal vein causes the vein to swell and the smaller the winding. Surface veins become swollen and blood can seep into the retina.

Retinal vein blockage is especially true in the elderly who suffer from glaucoma, diabetes, high blood pressure or a condition where the blood becomes more viscous (ie, too many red blood cells).

Retinal vein blockage causes a decrease in vision fungi occurring more slowly than the retinal artery obstruction. Changes that occur in the form of the growth of abnormal new blood vessels in the retina and the onset of glaucoma.

Fluorescence angiography can help determine the extent of the damage and plan treatment. To destroy abnormal blood vessels that can be used laser.

Retinal vein dilation can be done by inhaling a mixture of carbon dioxide and oxygen. In this way the blockage will move down, thereby reducing the retinal area affected.
