Recognize the Types of Strokes That Attack the Eye

Many people think that a stroke only occurs in the brain. In fact, a stroke can also attack the eye. One of the causes of eye strokes is the blockage of blood vessels leading to the retina. There are several types of strokes that commonly attack the eye, and one of them is central retinal occlusion. Just like a stroke in general, eye strokes are caused by a blockage or rupture of blood vessels leading to the eye. These conditions make the blood supply to the retina reduced, thereby causing interference with vision, even blindness.

Getting to know the common types of strokes attacking the eye

Based on the location of the blocked blood vessels, eye strokes can be divided into several types, namely:

Central retinal occlusion

This type of eye stroke occurs due to a blockage in the main blood vessels leading to the eye nerve. These conditions cause the eye nerves to not get blood supply. Most cases of eye strokes due to central retinal occlusion occur unnoticed because they do not cause any symptoms before, and can directly cause vision loss. When central retinal occlusion occurs, complaints and problems with vision will occur in the form of:
  • Decreased ability to see suddenly in one eye.
  • Vision becomes blurred in one eye suddenly.
  • Decreased visual ability, for several weeks.
In eye strokes due to central retinal occlusion, care must be taken immediately. This aims to prevent permanent nerve damage that will lead to blindness.

Retinal branch occlusion

This type of eye stroke occurs when the blockage is only in one branch of the blood vessels leading to the retina. The blockage causes some of the retina to lack blood and oxygen, resulting in sudden visual disturbances. Visual disturbances that occur during a stroke in the eyes of the retinal occlusion branch can be:
  • A foggy view (floaters).
  • Loss of some ability to see.
  • The ability to see can be lost completely or only at the edges.
Generally, treatment for retinal occlusion eye strokes aims to maintain the ability of vision does not disappear permanently. Therefore, doctors can provide treatment in the form of drug therapy or laser surgery.

Giant cell arteritis (GCA)

Other eye strokes are caused by giant cell arteritis (GCA). Giant cell arteritis is a condition in which the lining of the arteries becomes inflamed and swollen, thereby reducing blood supply throughout the body. Although it can occur in arteries in any part of the body, this condition is more common in the arteries in the temples. In the eyes, this condition can cause complaints in the form of blurred vision or even permanent blindness in one eye. Because it can attack other arteries in the body, GCA can also cause general complaints in the form of fever, dizziness, fatigue, joint stiffness, muscle aches, jaw pain when chewing or talking, and sudden weight loss. Giant cell arteritis must get treatment immediately. If not, the condition can cause permanent blindness. The three types of strokes that attack the eye above need to be aware of. Especially if you suffer from diabetes, high cholesterol, hypertension, heart disease, and glaucoma. Immediately consult an eye doctor if you experience the symptoms described above, so that treatment can be given as soon as possible.
