Why is blurred vision related to stroke?
According to Dr. Thuy, blurred vision can warn of the risk of stroke for the following reasons:
- Due to blockage of blood vessels in the brain
One of the common causes of stroke is when the blood vessels supplying blood to the brain are blocked, leading to a lack of oxygen and nutrients in the brain. If the blockage occurs in areas of the brain related to visual function, it can cause blurred vision or partial vision loss.
- Hemorrhagic stroke
When a blood vessel in the brain ruptures, blood flows into surrounding areas, which can increase pressure on brain tissue and affect vision. This condition can also lead to blurred vision or vision loss.
- Affects brain areas related to vision
Areas of the brain that control vision (such as the visual cortex at the back of the brain) can be damaged by stroke. This can cause the patient to feel blurred vision in one or both eyes.
4 factors that increase the risk of stroke related to blurred vision
- High blood pressure (hypertension): This is one of the important risk factors leading to stroke. High blood pressure can increase the risk of blood vessels in the brain rupturing or forming blood clots.
- Cardiovascular disease: Heart problems, such as arrhythmia (heart rhythm disorder), can create blood clots that travel to the brain, causing blockage of blood vessels in the brain.
- Diabetes: People with diabetes are at high risk of problems related to blood vessels and increase the risk of stroke.
- S,mo,king and drinking a.lco.hol: These unhealthy habits increase the risk of blood vessel blockage, contributing to the increased possibility of stroke.
How to prevent stroke when there are signs of blurred vision
According to ThS. BS. Pham Thi Thuy, not everyone understands stroke and its signs. Some people think that stroke only occurs in the elderly or people with underlying diseases, so they do not think that they can get it.
In fact, many people when experiencing signs of blurred vision subjectively think that it is an eye problem such as nearsightedness, eye inflammation, or other problems, without realizing that it could be a sign of stroke.
Confusing blurred vision due to stroke with eye diseases is a common problem and subjectivity can lead to serious consequences that cause the patient to lose the opportunity for early treatment or leave severe sequelae.
Therefore, if you or a loved one has signs of sudden blurred vision, especially accompanied by symptoms such as muscle weakness, difficulty speaking, or loss of balance, go to the hospital immediately for timely emergency care.
