CAN READING THE BLOOD VESSELS OF THE EYES DETECT ANY ILLNESS?
Yes, reading the blood vessels of the eyes
(also known as ocular vascular examination) can help detect various
health conditions. The blood vessels in the eyes—especially in the retina—are
closely connected to overall cardiovascular and systemic health. Eye exams can
reveal early signs of illnesses, sometimes even before symptoms appear.
What Illnesses Can Be
Detected?
1.
Hypertension (High Blood Pressure)
- Signs in the eyes: Narrowing
of retinal arteries, hemorrhages, or swelling of the optic nerve.
- Why it matters:
Prolonged hypertension can lead to vision loss or stroke.
2. Diabetes
(Diabetic Retinopathy)
- Signs in the eyes: Leaky
or damaged blood vessels in the retina, microaneurysms, or retinal
swelling.
- Why it matters:
Diabetic retinopathy is a leading cause of blindness if untreated.
3. High
Cholesterol
- Signs in the eyes:
Cholesterol deposits in the cornea (arcus senilis) or retinal artery
blockages.
- Why it matters: This
can indicate an increased risk of heart disease or stroke.
4. Stroke
Risk
- Signs in the eyes:
Retinal artery occlusion or signs of blood clots in retinal vessels.
- Why it matters:
Retinal changes can indicate a high risk of future stroke.
5.
Autoimmune Diseases
- Signs in the eyes:
Inflammation of blood vessels in the eye (vasculitis) or optic neuritis.
- Examples: Lupus, rheumatoid arthritis, or multiple
sclerosis.
6. Liver
Disease
- Signs in the eyes:
Yellowing of the whites of the eyes (jaundice), which indicates
elevated bilirubin levels.
7. Anemia
- Signs in the eyes: Pale
or white appearance in the conjunctiva (the inner part of the lower
eyelid).
How Are Eye Blood Vessels
Examined?
- Fundoscopy (Retinal Exam): A
doctor uses a special instrument to examine the retina.
- Optical Coherence Tomography (OCT): Provides high-resolution images of the retina.
- Slit-Lamp Examination:
Detects abnormalities in the front part of the eye.
