The retina is home to many small blood vessels and has a similar structure to the cerebral vascular system. Therefore, abnormal changes in retinal blood vessels can reflect the state of cerebral circulation.
Many studies show that:
- People with retinal microvascular damage are at higher risk of developing ischemic stroke.
- The presence of retinal hemorrhage, retinal stenosis, or retinal vascular occlusion is closely associated with the risk of cerebral infarction.
- Chronic diseases such as high blood pressure and diabetes often cause changes in the retina before complications appear in the brain.
- This means that, with just a regular eye exam, your doctor can spot early warning signs of a stroke.
2. Abnormal signs in retinal blood vessels
Some common symptoms when retinal blood vessels are damaged:
- Blurred vision, sudden or intermittent loss of vision.
- Black spots, flashes of light, or dark areas appear in your vision.
- Prolonged high blood pressure causes retinal blood vessels to constrict, easily leading to retinal damage.
- When examining the fundus, doctors can detect: retinal hemorrhage, optic papilledema, retinal artery stenosis.
- These signs not only affect vision but are also warning signs of a stroke that need to be noted.
3. Why is it necessary to check retinal blood vessels periodically?
Retinal examination not only helps protect vision but also brings many values in stroke prevention:
- Early detection of cerebrovascular risk: Small changes in the retina can signal high blood pressure or atherosclerosis.
- Assisting doctors in accurate diagnosis: When combined with carotid Doppler ultrasound, brain MRI or blood tests, retinal imaging helps comprehensively assess stroke risk.
- Monitor disease progression: People with diabetes and high blood pressure need regular eye exams to control vascular complications.
4. How to protect retinal vascular health
To maintain healthy retinal blood vessels, thereby reducing the risk of stroke, you should:
- Control blood pressure and blood sugar at stable levels.
- Eat healthy: limit saturated fat, increase green vegetables, fish and whole grains.
- Do not smoke and limit alcohol, because these are factors that directly damage blood vessels.
- Regular eye exams: especially for people over 40 years old, people with cardiovascular disease or family history of stroke.
5. The role of stroke screening through eye exams
Nowadays, many advanced medical facilities have included retinal vascular examination in the comprehensive stroke screening package. This is considered a simple, minimally invasive method but brings great value in diagnosis.
Screening helps:
- Early identification of high-risk subjects.
- Have a backup plan and timely treatment.
- Significantly reduces the rate of stroke and dangerous complications.
Conclude
Retinal vascular health is a “mirror” of cerebral circulation. Regular eye examinations not only protect vision but also help detect stroke risk early, thereby proactively preventing it effectively.
