Blackness in front of the eyes of the elderly may be a precursor to cerebral infarction. Cerebral infarction has a high disability rate, high mortality rate, and high recurrence rate, so it must be taken seriously!

Blackness in front of the eyes of the elderly may be a precursor to cerebral infarction. Cerebral infarction has a high disability rate, high mortality rate, and high recurrence rate, so it must be taken seriously!

Transient blackouts usually occur as sudden blacking out of the eyes and blurred vision, but they recover on their own within a few minutes.

The elderly are prone to arteriosclerosis, and atherosclerotic plaques can cause carotid artery stenosis and occlusion. The debris left after the plaque falls off may also block smaller blood vessels with the blood flow, causing cerebral artery occlusion.

When the carotid artery is narrowed or blocked, the body's blood pressure regulation function is impaired. Therefore, patients with carotid artery narrowing or blockage are prone to "blackouts". This blackout is often a precursor to cerebral infarction.

Why does problems with the eyes lead to problems with the brain?
The brain and eyes are both supplied with blood by the carotid artery. Once the carotid artery is narrowed or blocked, the brain and eyes will be deprived of blood. The human body is more sensitive to deprivation of blood to the eyes.
The ophthalmic artery branches off from the carotid artery and is most sensitive to carotid sclerosis, stenosis, and ischemia. Therefore, blacking out in front of the eyes (especially on one side) is often the earliest or even the only "alarm" of carotid stenosis.
Studies have shown that cerebral infarction is closely related to carotid artery stenosis. If you start treatment actively when you experience black vision, you can effectively prevent cerebral infarction.
Unfortunately, many people do not understand the relationship between blacking out of vision and cerebral infarction. They think that it will be fine in a while and there is no need to go to the hospital. As a result, they miss the best time for diagnosis and treatment.

If people with the following 7 risk factors often experience black spots in front of their eyes, it is recommended that they seek medical attention as soon as possible to check for the risk of cerebral infarction.
1. Old age
2. Smoking
3. Hypertension
4. Hyperlipidemia
5. Diabetes
6. Heart disease
7. For sleep apnea syndrome, it is recommended to see a neurology doctor as soon as possible. Use cranial CT or MRI to check whether cerebral infarction has occurred, so as not to delay the best time for diagnosis and treatment. If cerebral infarction is ruled out, it is necessary to continue to investigate the cause of amaurosis so as to take targeted preventive measures. It is recommended to use carotid artery ultrasound to rule out carotid artery stenosis.
